DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

INTRODUCTION

The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The

Command Line Interface (CLI) can be used to configure and manage the Switch via the serial port or Telnet interfaces.

The DGS-3400 Layer 2 stackable Gigabit Ethernet switch series are members of the D-Link xStack® family. Ranging from 10/100Mbps edge switches to core gigabit switches, the xStack® switch family has been future-proof designed to provide a stacking architecture with fault tolerance, flexibility, port density, robust security and maximum throughput with a user-friendly management interface for the networking professional.

This manual provides a reference for all of the commands contained in the CLI for the xStack® DGS-3426, DGS-3427,

DGS-3450 and DGS-3426P series of switches. Configuration and management of the Switch via the Web-based management agent is discussed in the User’s Guide.

NOTE: For the remainder of this manual, all versions of the DGS-3426, DGS-3427, DGS-3450, and

DGS-3426P switches will be referred to as simply the Switch or the DGS-3450.

Accessing the Switch via the Serial Port

The Switch’s serial port’s default settings are as follows:

•

115200 baud

• no parity

•

8 data bits

•

1 stop bit

A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above is then connected to the Switch’s serial port via an RS-232 DB-9 cable.

With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not appear, try pressing Ctrl+r o refresh the console screen.

Figure 1-1. Initial CLI screen

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor

3650:admin# . This is the command line where all commands are input.

Setting the Switch’s IP Address

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your networking address scheme.

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found on the initial boot console screen – shown below.

Device Discovery ........................................ -

Figure 1-2. Boot screen

The Switch’s MAC address can also be found in the Web management program on the Switch Information (Basic

Settings) window in the Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the

Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

1. Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy

. Where the x ’s represent the IP address to be assigned to the IP interface named System and the y ’s represent the corresponding subnet mask.

2. Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z . Where the x ’s represent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

DGS-3450:admin# config ipif System ipaddress 10.24.22.200/255.0.0.0

Command: config ipif System ipaddress 10.24.22.200/8

Success.

DGS-3450:admin#

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.24.22.200 with a subnet mask of 255.0.0.0. The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet, SNMP MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

U SING THE C ONSOLE CLI

The Switch supports a console management interface that allows the user to connect to the Switch’s management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the Switch to use SNMPbased network management software over the network.

This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation.

NOTE: Switch configuration settings are saved to non-volatile RAM using the save command. The current configuration will then be retained in the Switch’s NV-RAM, and reloaded when the Switch is rebooted. If the Switch is rebooted without using the save command, the last configuration saved to NV-RAM will be loaded.

Connecting to the Switch

The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C serial cable. Your terminal parameters will need to be set to:

•

VT-100 compatible

•

115200 baud

•

8 data bits

•

No parity

•

One stop bit

No flow control

Users can also access the same functions over a Telnet interface. Once an IP address has been set for the Switch, users can use a Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether accessed from the console port or from a Telnet interface.

After the Switch reboots and you have logged in, the console looks like this:

A CCESS A UTHENTICATION C ONTROL C OMMANDS

The TACACS / XTACACS / TACACS+ / RADIUS commands allow users to secure access to the Switch using the

TACACS / XTACACS / TACACS+ / RADIUS protocols. When a user logs in to the Switch or tries to access the administrator level privilege, he or she is prompted for a password. If TACACS / XTACACS / TACACS+ / RADIUS authentication is enabled on the Switch, it will contact a TACACS / XTACACS / TACACS+ / RADIUS server to verify the user. If the user is verified, he or she is granted access to the Switch.

There are currently three versions of the TACACS security protocol, each a separate entity. The Switch’s software supports the following versions of TACACS:

•

TACACS (Terminal Access Controller Access Control System) —Provides password checking and authentication, and notification of user actions for security purposes utilizing via one or more centralized TACACS servers, utilizing the UDP protocol for packet transmission.

•

Extended TACACS (XTACACS) — An extension of the TACACS protocol with the ability to provide more types of authentication requests and more types of response codes than TACACS. This protocol also uses UDP to transmit packets.

•

TACACS+ (Terminal Access Controller Access Control System plus) — Provides detailed access control for authentication for network devices. TACACS+ is facilitated through Authentication commands via one or more centralized servers. The TACACS+ protocol encrypts all traffic between the Switch and the TACACS+ daemon, using the TCP protocol to ensure reliable delivery.

The Switch also supports the RADIUS protocol for authentication using the Access Authentication Control commands.

RADIUS or Remote Authentication Dial In User Server also uses a remote server for authentication and can be responsible for receiving user connection requests, authenticating the user and returning all configuration information necessary for the client to deliver service through the user. RADIUS may be facilitated on this Switch using the commands listed in this section.

In order for the TACACS / XTACACS / TACACS+ / RADIUS security function to work properly, a TACACS / XTACACS /

TACACS+ / RADIUS server must be configured on a device other than the Switch, called a server host and it must include usernames and passwords for authentication. When the user is prompted by the Switch to enter usernames and passwords for authentication, the Switch contacts the TACACS / XTACACS / TACACS+ / RADIUS server to verify, and the server will respond with one of three messages: a. The server verifies the username and password, and the user is granted normal user privileges on the Switch. b. The server will not accept the username and password and the user is denied access to the Switch. c. The server doesn’t respond to the verification query. At this point, the Switch receives the timeout from the server and then moves to the next method of verification configured in the method list.

The Switch has four built-in server groups, one for each of the TACACS, XTACACS, TACACS+ and RADIUS protocols.

These built-in server groups are used to authenticate users trying to access the Switch. The users will set server hosts in a preferable order in the built-in server group and when a user tries to gain access to the Switch, the Switch will ask the first server host for authentication. If no authentication is made, the second server host in the list will be queried, and so on. The built-in server group can only have hosts that are running the specified protocol. For example, the TACACS server group can only have TACACS server hosts.

The administrator for the Switch may set up five different authentication techniques per user-defined method list

(TACACS / XTACACS / TACACS+ / RADIUS / local / none) for authentication. These techniques will be listed in an order preferable, and defined by the user for normal user authentication on the Switch, and may contain up to eight authentication techniques. When a user attempts to access the Switch, the Switch will select the first technique listed for authentication. If the first technique goes through its server hosts and no authentication is returned, the Switch will then go to the next technique listed in the server group for authentication, until the authentication has been verified or denied, or the list is exhausted.

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

Please note that user granted access to the Switch will be granted normal user privileges on the Switch. To gain access to admin level privileges, the user must enter the enable admin command and then enter a password, which was previously configured by the administrator of the Switch.

NOTE: TACACS, XTACACS and TACACS+ are separate entities and are not compatible. The Switch and the server must be configured exactly the same, using the same protocol. (For example, if the

Switch is set up for TACACS authentication, so must be the host server.)

The Access Authentication Control commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Restrictions

This command is used to configure user accounts. config account <username> {encrypt [plain_text | sha_1] <password>}

When the password information is not specified in the command, the system will prompt the user to input the password interactively. In this case, the user can only input a plain text password.

If the user specifies a password in the command, the user can select to input the password in plain text form or in encrypted form. The encryption algorithm is based on SHA-1.

<username> - Specify the name of the account. The account must already be defined. plain_text - Specify the password in plain text form. sha_1 - Specify the password in SHA-1 encrypted form. password - The password for the user account. The length of a password in plain-text form and encrypted form are different. For a plain-text form password, the password must be a minimum of 0 characters and a maximum of 15 characters. For an encrypted form password, the length is fixed to 35 bytes long. The password is case-sensitive.

Only Administrator can issue this command.

Restrictions

This command is used to enter the administrator level privilege enable admin

Promote the "user" privilege level to "admin" level. When the user enters this command, the authentication method tacacs, xtacacs, tacacs+, user-defined server groups, local_enable or none will be used to authenticate the user. Since TACACS, XTACACS and RADIUS do not support the "enable" function by their selves,, if the user wants to use either one of these three protocols to enable authentication, the user must create a special account on the server host first, which has a username of "enable", and then configure its password as the enable password to support the "enable" function.

This command can not be used when the authentication policy is disabled.

For switches with 3-levels of privilege, this command can be used by users with user level and operator level privileges to access the administrator privilege level.

Restrictions

This command is used to configure the local enable password of the administrator level privilege. config admin local_enable

Configure the local enable password for the enable command. When the user chooses the

“local_enable” method to promote the privilege level, the enable password of the local device is needed.

When the password information is not specified in the command, the system will prompt the user to input the password interactively. In this case, the user can only input a plain text password. If the password is present in the command, the user can select to input the password in plain text or encrypted form. The encryption algorithm is based on SHA-1.

None.

Only Administrator can issue this command.

<value 0-63> | drop] {counter [enable |disable]} violate [permit | replace_dscp <value 0-

63> | drop] {counter [enable |disable]} | delete]

This command is used to configure the flow-based metering function. The metering function support three modes, single rate two colors, single rate three color, and two rate three color.

The access rule must first be created before the parameters of this function can be applied.

For the single rate two color mode, users may set the preferred bandwidth for this rule, in

Kbps and once the bandwidth has been exceeded, overflow packets will be either dropped or be set to a drop precedence, depending on user configuration. The drop precedence will be used by RED. With RED, the packet with higher drop precedence will be dropped with higher probability.

For the single rate three color mode, users need to specify the committed rate in Kbps, the commited burst size and the excess burst size.

For the two rate three color mode, users need to specify the committed rate in Kbps, the commited burst size, the peak rate and the peak burst size.

There can be two cases to map the color of packet, color blind mode and color aware mode.

In the color-blind case, the determination for the color of packet is based on metering result.

In the color-aware case, the determination for the color of packet is based metering result and the ingress DSCP.

When the color blind or color aware is not specified, color blind is the default mode.

The green color packet will be treated the conforming action, the yellow color packet will be

ACL FLOW M ETERING C OMMANDS

Before configuring the ACL Flow Meter, here is a list of acronyms and terms users will need to know. trTCM – Two Rate Three Color Marker. This, along with the srTCM, are two methods available on the switch for metering and marking packet flow. The trTCM meters and IP flow and marks it as a color based on the flow’s surpassing of two rates, the CIR and the PIR.

•

CIR – Committed Information Rate. Common to both the trTCM and the srTCM, the CIR is measured in bytes of

IP packets. IP packet bytes are measured by taking the size of the IP header but not the link specific headers.

For the trTCM, the packet flow is marked green if it doesn’t exceed the CIR and yellow if it does. The configured rate of the CIR must not exceed that of the PIR. The CIR can also be configured for unexpected packet bursts using the CBS and PBS fields.

•

CBS – Committed Burst Size. Measured in bytes, the CBS is associated with the CIR and is used to identify packets that exceed the normal boundaries of packet size. The CBS should be configured to accept the biggest

IP packet that is expected in the IP flow.

•

PIR – Peak Information Rate. This rate is measured in bytes of IP packets. IP packet bytes are measured by taking the size of the IP header but not the link specific headers. If the packet flow exceeds the PIR, that packet flow is marked red. The PIR must be configured to be equal or more than that of the CIR.

•

PBS – Peak Burst Size. Measured in bytes, the PBS is associated with the PIR and is used to identify packets that exceed the normal boundaries of packet size. The PBS should be configured to accept the biggest IP packet that is expected in the IP flow. srTCM – Single Rate Three Color Marker. This, along with the trTCM, are two methods available on the switch for metering and marking packet flow. The srTCM marks its IP packet flow based on the configured CBS and EBS. A packet flow that does not reach the CBS is marked green, if it exceeds the CBS but not the EBS its marked yellow, and if it exceeds the EBS its marked red.

•

IP packet that is expected in the IP flow.

•

EBS – Excess Burst Size. Measured in bytes, the EBS is associated with the CIR and is used to identify packets that exceed the boundaries of the CBS packet size. The EBS is to be configured for an equal or larger rate than the CBS.

DSCP – Differentiated Services Code Point. The part of the packet header where the color will be added. Users may change the DSCP field of incoming packets.

The ACL Flow Meter function will allow users to color code IP packet flows based on the rate of incoming packets. Users have two types of Flow metering to choose from, trTCM and srTCM, as explained previously. When a packet flow is placed in a color code, the user can choose what to do with packets that have exceeded that color-coded rate.

Green – When an IP flow is in the green mode, its configurable parameters can be set in the Conform field, where the packets can have their DSCP field changed. This is an acceptable flow rate for the ACL Flow Meter function.

Yellow – When an IP flow is in the yellow mode, its configurable parameters can be set in the Exceed field. Users may choose to either Permit or Drop exceeded packets. Users may also choose to change the DSCP field of the packets.

Red – When an IP flow is in the red mode, its configurable parameters can be set in the Exceed field. Users may choose to either Permit or Drop exceeded packets. Users may also choose to change the DSCP field of the packets.

Users may also choose to count exceeded packets by clicking the Counter check box. If the counter is enabled, the counter setting in the access profile will be disabled.

BPDU A TTACK P ROTECTION C OMMANDS

Users at different sites connected across a service-provider network need to use various Layer 2 protocols to scale their topologies to include all remote sites, as well as the local sites. STP must run properly, and every VLAN should build a proper spanning tree that includes the local site and all remote sites across the service-provider network.

Layer 2 protocol tunneling is a feature designed for service providers who carry traffic of multiple customers across their networks and are required to maintain the Layer 2 protocol configurations of each customer without impacting the traffic of other customers.

The BPDU Attack Protection commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command config bpdu_protection ports

Parameters

[<portlist> | all ] {state [enable | disable] | mode [ drop | block | shutdown} (1) config bpdu_protection recovery_timer [<sec 60-1000000> | infinite] config bpdu_protection enable bpdu_protection

[trap | log ] [ none | attack_detected | attack_cleared | both ] disable bpdu_protection show bpdu_protection {ports {<portlist>}}

Each command is listed, in detail, in the following sections.

config bpdu_protection ports

Purpose

Syntax

Description

Parameters

Used to configure bpdu_protection state and mode. config bpdu_protection ports [<portlist> | all ] {state [enable | disable] | mode [ drop | block | shutdown} (1)

The config bpdu_protection ports command is used to configure the BPDP protection function for the ports on the switch. In generally, there are two states in BPDU protection function. One is normal state, and another is under attack state. The under attack state have three modes: drop, block, and shutdown. A BPDU protection enabled port will enter under attack state when it receives one STP BPDU packet. And it will take action based on the configuration. Thus, BPDU protection can only be enabled on STP disabled port.

BPDU protection has high priority than fbpdu setting configured by configure STP command in determination of BPDU handling. That is, when fbpbu is configured to forward STP BPDU but BPDU protection is enabled, then the port will not forward STP BPDU.

BPDU protection also has high priority than BPDU tunnel port setting in determination of

BPDU handling.

That is, when a port is configured as BPDU tunnel port for STP, it will forward STP BPDU.

But if the port is BPDU protection enabled. Then the port will not forward STP BPDU portlist - Specified a range of ports to be configured (port number). all - For set all ports in the system, you may use “all” parameter. state - Specified the bpdu_protection state. The default state is disable enable - Enable bpdu_protection disable - Disable bpdu_protection mode - Specified the bpdu_protection mode. The default mode is shutdown drop - Drop all received BPDU packets when the port enters under_attack state. block - Drop all packets (include BPDU and normal packets) when the port enters under _attack state. shutdown - Shut down the port when the port enters under_attack state.

When a port enters under attack state, it can be disabled or blocked based on the configuration. The state can be recovered manually or by the auto recovery mechanism. This command is used to configure the auto-recovery timer. To manually recover the port, the user needs to disable and re-enable the port. recovery_timer - Specified the bpdu_protection Auto-Recovery recovery_timer. The default value of recovery_timer is 60. infinite - The port will not be auto recovered.

<sec 60 –1000000> - The timer (in seconds) used by the Auto-Recovery mechanism to recover the port. The valid range is 60 to 1000000.

The command logging function is used to log the commands that have successfully been configured to the switch via the command line interface. The requirement is to log the command itself, along with information about the user account that entered the command into the system log and the informational severity level. Commands that do not cause a change in the switch configuration or operation (such as show) will not be logged. A save command will change the configuration file hence it will be logged. Information about saving or viewing the system log is described in the syslog functional specification and is out of the scope of this UIS.

The Command Logging commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

The user can use this command to configure authorization mode and authentication method on ports. portlist - Specify port(s) to configure. auth_mode - port_based - If one of the attached hosts passes the authentication, all hosts on the same port will be granted to access network. If the user fails to authorize, this port will keep trying the next authentication host_based - Every user can be authenticated individually. V2.01 and later, can authenticate client on specific authentication VLAN(s). vlanid - Specific authentication VLAN(s). enable - Assign the specified VID list as authentication VLAN(s). disable - Remove the specified VID list from authentication VLAN(s).

If "vlanid" is not specified, or all VLANs is disabled,means do not care whitch VLAN the client comes from,the client will be authenticated if the client's MAC(not care the VLAN) is not authenticated. After the client is authenticated,the client will not be re-authenticated when received from other VLANs.

All VLANs are disabled by default.

NOTE: When port’s authorization mode is changed to port based, previously authentication

VLAN(s) on this port will be clear. multi_authen_methods - Specifies the method for compound authentication. none - Compound authentication is not enabled,

For project that support single authentication mode, the authentication method is defined by individual authentication module.

For project that does not support single authentication mode, access authentication is disabled on the port. any - If any one of the authentication method (802.1X, MAC-AC, WAC and JWAC) passes, then pass. dot1x_impb - Dot1x will be verified first, and then IMPB will be verified.

DHCP S ERVER S CREENING C OMMANDS

The DHCP Server Screening Commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

The DHCP Server Screening commands allow you not only to restrict all DHCP Server packets but also to receive any specified DHCP server packets by any specified DHCP client, it is useful when one or more than one DHCP servers are present on the network and both provide DHCP services to different distinct groups of clients. Enabling the DHCP filter for the first time will create both an access profile and access rule per port, following this other access rules can be created.

These rules are used to block all DHCP server packets. Similarly, the addition of a permit DHCP entry will create one access profile and one access rule the first time the DHCP client MAC address is the client MAC address, and the Source

IP address is the same as the DHCP server’s IP address (UDP port number 67). These rules are used to permit the

DHCP server packets with specific fileds, which the user configures.

When the DHCP Server filter function is enabled, all DHCP Server packets will be filtered from a specific port. Also, you are allowed to create entries for specific port-based Server IP address and Client MAC address binding entries. Be aware that the DHCP Server filter function must be enabled first. Once all settings are complete, all DHCP Server packets will be filtered from a specific port except those that meet the Server IP Address and Client MAC Address binding.

Command Parameters config filter dhcp_server [add permit server_ip <ipaddr> {client_mac <macaddr>} ports [<portlist>|all] | delete permit server_ip <ipaddr> {client_mac <macaddr>} ports [<portlist>|all] | ports [<portlist>|all] state [enable|disable]] show filter dhcp_server config filter dhcp_server trap_log [enable | disable] config filter dhcp_server illegal_server_log_suppress_duration

[ 1min | 5min | 30min ]

Each command is listed in detail in the following sections.

config filter dhcp_server

Purpose

Syntax

Description

Parameters

DHCP server packets except those that have been IP/client MAC bound will be filtered. This command is used to configure the state of the function for filtering of DHCP server packet and to add/delete the DHCP server/client binding entry. config filter dhcp_server [add permit server_ip <ipaddr> {client_mac <macaddr>} ports

[<portlist>|all] | delete permit server_ip <ipaddr> {client_mac <macaddr>} ports

[<portlist>|all] | ports [<portlist>|all] state [enable|disable]]

This command has two purposes: to filter all DHCP server packets on the specified port(s) and to allow some DHCP server packets to be forwarded if they are on the pre-defined server

IP address/MAC address binding list. Thus the DHCP server can be restricted to service a specified DHCP client. This is useful when there are two or more DHCP servers present on a network. ipaddr – The IP address of the DHCP server to be filtered. macaddr – The MAC address of the DHCP client. state – To Enable/disable the filter DHCP server state. portlist – The port list of filter DHCP server.

DHCP S ERVER C OMMANDS

For this release, the Switch now has the capability to act as a DHCP server to devices within its locally attached network.

DHCP, or Dynamic Host Configuration Protocol, allows the switch to delegate IP addresses, subnet masks, default gateways and other IP parameters to devices that request this information. This occurs when a DHCP enabled device is booted on or attached to the locally attached network. This device is known as the DHCP client and when enabled, it will emit query messages on the network before any IP parameters are set. When the DHCP server receives this request, it returns a response to the client, containing the previously mentioned IP information that the DHCP client then utilizes and sets on its local configurations.

The user can configure many DHCP related parameters that it will utilize on its locally attached network, to control and limit the IP settings of clients desiring an automatic IP configuration, such as the lease time of the allotted IP address, the range of IP addresses that will be allowed in its DHCP pool, the ability to exclude various IP addresses within the pool as not to make identical entries on its network, or to assign the IP address of an important device (such as a DNS server or the IP address of the default route) to another device on the network.

Users also have the ability to bind IP addresses within the DHCP pool to specific MAC addresses in order to keep consistent the IP addresses of devices that may be important to the upkeep of the network that require a static IP address.

The DHCP Server Commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

The command is used to configure the DHCPv6 client state for one interface. ipif <ipif_name 12> - The name of the IP interface. ipaddress <network_address> - Configures a network on an IP interface. The address should specify a host address and length of network mask. Since an IP interface can have only one

IPv4 address, the newly configured address will overwrite the original one. vlan <vlan_name 32> - Name of the VLAN where the IPIF is operated. proxy_arp - Enable or disable the proxy ARP function. This is for the IPv4 function. Default:

Disabled. local - This setting controls whether the system provides the proxy reply for the ARP packets destined for an IP address located in the same interface as the received interface.

When proxy ARP is enabled for an interface, the system will do the proxy reply for the ARP packets destined for an IP address located in a different interface. For ARP packets destined for an IP address located in the same interface, the system will check this setting to determine whether to reply. Default: Disabled. state - Enable or disable the state of the IP interface. bootp - Use BOOTP to obtain the IPv4 address. dhcp - Use DHCP to obtain the IPv4 address. ipv6 ipv6address - IPv6 network address: The address should specify a host address and length of network prefix. There can be multiple V6 addresses defined on an interface. Thus, as a new address is defined, it is added on this IP interface. dhcpv6_client - See below: enable - Enable the DHCPv6 client state of the interface. disable - Disable the DHCPv6 client state of the interface.

Only Administrator and Operator-level users can issue this command.

D-L INK S INGLE IP M ANAGEMENT C OMMANDS

Simply put, D-Link Single IP Management is a concept that will stack switches together over Ethernet instead of using stacking ports or modules. Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following rules:

SIM is an optional feature on the Switch and can easily be enabled or disabled. SIM grouping has no effect on the normal operation of the Switch in the user’s network.

There are three classifications for switches using SIM. The Commander Switch(CS), which is the master switch of the group, Member Switch(MS), which is a switch that is recognized by the CS a member of a SIM group, and a Candidate

Switch (CaS), which is a switch that has a physical link to the SIM group but has not been recognized by the CS as a member of the SIM group.

A SIM group can only have one Commander Switch(CS). All switches in a particular SIM group must be in the same IP subnet (broadcast domain). Members of a SIM group cannot cross a router. A SIM group accepts up to 33 switches

(numbered 0-32), including the Commander Switch (numbered 0). There is no limit to the number of SIM groups in the same IP subnet (broadcast domain), however a single switch can only belong to one group. If multiple VLANs are configured, the SIM group will only utilize the management VLAN on any switch. SIM allows intermediate devices that do not support SIM. This enables the user to manage a switch that are more than one hop away from the CS.

The SIM group is a group of switches that are managed as a single entity. The DGS-3400 Series may take on three different roles:

1. Commander Switch (CS) – This is a switch that has been manually configured as the controlling device for a group, and takes on the following characteristics: a. It has an IP Address. b. It is not a Commander Switch or Member Switch of another Single IP group. c. It is connected to the Member Switches through its management VLAN.

2. Member Switch (MS) – This is a switch that has joined a single IP group and is accessible from the CS, and it takes on the following characteristics: a. It is not a CS or MS of another IP group. b. It is connected to the CS through the CS management VLAN.

3. Candidate Switch (CaS) – This is a switch that is ready to join a SIM group but is not yet a member of the SIM group. The Candidate Switch may join the SIM group through an automatic function of the DGS-3400, or by manually configuring it to be a MS of a SIM group. A switch configured as a CaS is not a member of a SIM group and will take on the following characteristics: a. It is not a CS or MS of another Single IP group. b. It is connected to the CS through the CS management VLAN.

The following rules also apply to the above roles:

1. Each device begins in the Candidate state.

2. CS’s must change their role to CaS and then to MS, to become a MS of a SIM group. Thus the CS cannot directly be converted to a MS.

3. The user can manually configure a CS to become a CaS.

4. A MS can become a CaS by: a. Being configured as a CaS through the CS. b. If report packets from the CS to the MS time out.

5. The user can manually configure a CaS to become a CS

6. The CaS can be configured through the CS to become a MS.

177

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

After configuring one switch to operate as the CS of a SIM group, additional xStack

DGS-3400 series switches may join the group by either an automatic method or by manually configuring the Switch to be a MS. The CS will then serve as the in band entry point for access to the MS. The CS’s IP address will become the path to all MS’s of the group and the CS’s

Administrator’s password, and/or authentication will control access to all MS’s of the SIM group.

With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets. The applications will decode the packet from the administrator, modify some data, then send it to the MS. After execution, the CS may receive a response packet from the MS, which it will encode and send back to the administrator.

When a CS becomes a MS, it automatically becomes a member of the first SNMP community (include read/write and read only) to which the CS belongs. However if a MS has its own IP address, it can belong to SNMP communities to which other switches in the group, including the CS, do not belong.

The Upgrade to v1.6

To better improve SIM management, the xStack

DGS-3400 Series switches have been upgraded to version 1.6 in this release. Many improvements have been made, including:

The Commander Switch (CS) now has the capability to automatically rediscover member switches that have left the SIM group, either through a reboot or web malfunction. This feature is accomplished through the use of Discover packets and

Maintain packets that previously set SIM members will emit after a reboot. Once a MS has had its MAC address and password saved to the CS’s database, if a reboot occurs in the MS, the CS will keep this MS information in its database and when a MS has been rediscovered, it will add the MS back into the SIM tree automatically. No configuration will be necessary to rediscover these switches. There are some instances where pre-saved MS switches cannot be rediscovered. For example, if the Switch is still powered down, if it has become the member of another group, or if it has been configured to be a Commander Switch, the rediscovery process cannot occur.

This version will support multiple switch upload and downloads for firmware, configuration files and log files, as follows:

•

Firmware – The switch now supports MS firmware downloads from a TFTP server.

•

Configuration Files – This switch now supports downloading and uploading of configuration files both to (for configuration restoration) and from (for configuration backup) MS’s, using a TFTP server..

•

Log – The switch now supports uploading MS log files to a TFTP server.

NOTE: For more details regarding improvements made in SIMv1.6, please refer to the Single

IP Management White Paper located on the D-Link website.

The SIM commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Parameters

Restrictions

Used to configure unidirectional link detection on port config duld ports [<portlist> | all ] {state [enable |disable] | mode [shutdown | normal] | discovery_time <sec 5-65535>}(1)

The command used to configure unidirectional link detection on ports.

Unidirectional link detection provides discovery mechanism based on 802.3ah to discovery its neighbor. If the OAM discovery can complete in configured discovery time, it concludes the link is bidirectional. Otherwise, it starts detecting task to detect the link status.

<portlist> - Specify a range of ports. state - Specifies these ports unidirectional link detection status. The default state is disabled. mode - See below: shutdown - If any unidirectional link is detected, disable the port and log an event. normal - Only log an event when a unidirectional link is detected. discovery_time - Specifies these ports neighbor discovery time. If the discovery is timeout, the unidirectional link detection will start. The default discovery time is 5 seconds.

Only Administrator and Operator-level users can issue this command.

Example usage:

To enable unidirectional link detection on port 1:

Parameters

Restrictions

Used to configure the DNS Resolver name server of the switch. config name_server [[add |delete ] <ipaddr> {primary} | timeout <second 1-60>]

The config name_server command is used to configure the DNS Resolver name server of the switch. Note that only when add a name server, the parameter “primary” will be resolved.

Other conditions won’t resolve the parameter “primary”. It means that when delete a name server, just check the IP address. If the IP address is the same to the name server’s, the name server will be deleted, don’t check the priority parameter.

When adding a name server, if one primary name server exists in the static name server table, then add a new primary name server, the existing primary name server will be changed to a normal name server. If the added primary name server’s IP address is the same to an existed normal name server’s IP address, the existing normal name server will be changed to a primary name server, but won’t add new name server. When no primary name server is specified, the first configured name server will auto change to primary name server.. If the deleted name server’s IP address equals to one of the existing name servers’ IP addresses, regardless whether a normal name server or primary name server, the name server will be deleted. add - Add DNS Resolver name server delete - Delete DNS Resolver name server ipaddr - The DNS Resolver name server IP address timeout - The maximum time waiting for a responce from a specified name server. primary - Specify the name server is a primary name server.

Only Administrator and Operator-level users can issue this command.

RPL port: Specifies one of the R-APS VLAN ring ports as the RPL port. To remove an RPL port from an R-APS VLAN, use the none designation for rpl_port.

RPL owner: Specifies the node as the RPL owner.

Note: The RPL port and RPL owner cannot be modified when ERPS is enabled; and the virtual channel cannot be configured as RPL. For example, if a ring port is configured on the virtual channel and the ring port is configured as an RPL port, an error message will be display and the configuration will fail. port - See below. west - Specifies the west ring port as the RPL port. east - Specifies the east ring port as the RPL port. none - No RPL port on this node. By default, the node has no RPL port. owner - See below. enable - Specifies the device as an RPL owner node. disable - This node is not an RPL owner. By default, the RPS owner is disabled.

Only Administrator and Operator-level users can issue this command.

config erps raps_vlan timer

Purpose

Syntax

Description

Used to configure the ERPS timers for a specific R-APS VLAN. config erps raps_vlan <vlanid> timer { holdoff_time <value 0-10000> | guard_time

<value 10-2000> | wtr_time <min 5-12>} (1)

This command is used to configure the protocol timers.

Holdoff timer: The Holdoff timer is used to filter out intermittent link faults when link failures occur during the protection switching process. When a ring node detects a link failure, it will start the holdoff timer and report the link failure event (R-APS BPDU with SF flag) after the link failure is confirmed within period of time specified.

Guard timer: Guard timer is used to prevent ring nodes from receiving outdated R-APS messages. This timer is used during the protection switching process after the link failure recovers. When the link node detects the recovery of the link, it will report the link failure recovery event (R-APS PDU with NR flag) and start the guard timer. Before the guard timer expires, all received R-APS messages are ignored by this ring node, except in the case where a burst of three R-APS event messages that indicates the topology of a sub-ring has changed and the node needs to flush FDB are received on the node. In this case the recovered link does not go into a blocking state. The Guard Timer should be greater than the maximum expected forwarding delay for which one R-APS message circles around the ring.

WTR timer: WTR timer is used to prevent frequent operation of the protection switch due to an intermittent defect. This timer is used during the protection switching process when a link failure recovers. It is only used by the RPL owner. When the RPL owner in protection state receives R-APS PDU with an NR flag, it will start the WTR timer. The RPL owner will block

IEEE 802.1Q

VLAN C OMMANDS

Along with normal VLAN configurations, this Switch now incorporate Double VLANs. Better known as Q-IN-Q VLANs,

Double VLANs allow network providers to expand their VLAN configurations to place VLANs within a larger inclusive

VLAN, which adds a new layer to the VLAN configuration. This basically lets large ISP's create L2 Virtual Private

Networks and also create transparent LANs for their customers, which will connect two or more customer LAN points without over complicating configurations on the client's side. Not only will over-complication be avoided, but now the administrator has over 4000 VLANs in which over 4000 VLANs can be placed, therefore greatly expanding the VLAN network.

Implementation of this feature adds a VLAN frame to an existing VLAN frame for the ISP VLAN recognition and classification. To ensure devices notice this added VLAN frame, an Ethernet encapsulation, here known as a tpid, is also added to the frame. The device recognizes this tpid and therefore checks the VLAN tagged packet to see if a provider

VLAN tag has been added. If so, the packet is then routed through this provider VLAN, which contains smaller VLANs with similar configurations to ensure speedy and guaranteed routing destination of the packet.

The IEEE 802.1Q VLAN commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command create vlan delete vlan config vlan config gvrp enable gvrp disable gvrp show vlan show gvrp enable double_vlan disable double_vlan create double_vlan config double_vlan

IGMP AND MLD S NOOPING C OMMANDS

The Internet Group Management Protocol (IGMP) is a Layer 4 protocol used to manage the membership of Internet

Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. IGMP snooping, as implied by the name, is a feature that allows a Layer 2 switch to "listen in" on the IGMP conversation between hosts and routers by processing the Layer 4 IGMP packets sent in a multicast network.

The Multicast Listener Discovery (MLD) is protocol used by an IPv6 router to discover the presence of multicast listeners

(that is, nodes wishing to receive multicast packets) on its directly attached links, and to discover specifically which multicast addresses are of interest to those neighboring nodes.

The IGMP and MLD Snooping commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Parameters

Restrictions

Used to configure IGMP snooping on the switch. config igmp_snooping [vlan <vlan_name 32> | all] {host_timeout <sec 1-16711450> | router_timeout <sec 1-16711450> | leave_timer <sec 1-16711450> | state

[enable|disable] | fast_leave [enable|disable] | report_suppression [enable | disable]}(1)

The config igmp_snooping command configures IGMP snooping on the switch.

Note: A fast leave enabled switch can not be attached to another report suppression enabled switch's downstream interface. That is, if switch A is attached to switch B's downstream interface, you can not enable the fast leave feature on switch A and enable report suppression on switch B simultaneously. vlan - Specify the name of the VLAN for which IGMP snooping is to be configured. All indicates all VLANs. host_timeout – Specify the host time-out value here. router_timeout – Specify the rouer time-out value here. leave_timer – Specify the leave timer value here. state - Enable or disable IGMP snooping for the chosen VLAN. fast_leave - Enable or disable the IGMP snooping fast leave function.

If enabled, the membership is immediately removed when the system receives the IGMP leave message. report_suppression - When IGMP report suppression is enabled (the default), the switch sends the first IGMP report from all hosts for a group to all the multicast routers. The switch does not send the remaining IGMP reports for the group to the multicast routers.

If the multicast router query includes requests only for IGMPv1 and IGMPv2 reports, the switch forwards only the first IGMPv1 or IGMPv2 report from all hosts for a group to all the multicast routers.

If the multicast router query also includes requests for IGMPv3 reports, the switch forwards all IGMPv3 reports for a group to the multicast devices.

Only Administrator and Operator-level users can issue this command.

Example usage:

To configure IGMP snooping:

config igmp_snooping querier

Purpose

Syntax

Description

Parameters

Used to configure the time in seconds between general query transmissions, the maximum time in seconds to wait for reports from members, and the permitted packet loss that guarantees IGMP snooping. config igmp_snooping querier [vlan <vlan_name 32> | all]{ query_interval <sec 1-

This command configures the IGMP snooping querier. vlan - Specify the name of the VLAN for which IGMP snooping querier is to be configured. query_interval - Specify the amount of time in seconds between general query transmissions.

The default setting is 125 seconds. max_reponse_time - Specify the maximum time in seconds to wait for reports from members.

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

config igmp_snooping querier

Restrictions

The default setting is 10 seconds. robustness_variable - Provides fine-tuning to allow for expected packet loss on a subnet. The value of the robustness variable is used in calculating the following IGMP message intervals:

•

Group member interval - Amount of time that must pass before a multicast router decides there are no more members of a group on a network. This interval is calculated as follows: (robustness variable x query interval) + (1 x query response interval).

•

Other querier present interval - Amount of time that must pass before a multicast router decides that there is no longer another multicast router that is the querier. This interval is calculated as follows: (robustness variable x query interval) + (0.5 x query response interval).

•

Last member query count - Number of group-specific queries sent before the router assumes there are no local members of a group. The default number is the value of the robustness variable.

•

By default , the robustness variable is set to 2. You might want to increase this value if you expect a subnet to be loosely. last_member_query_interval - Specify the maximum amount of time between group-specific query messages, including those sent in response to leave-group messages. You might lower this interval to reduce the amount of time it takes a router to detect the loss of the last member of a group.

On receiving a leave message, the router will assume there are no local members on the interface if there are no reports received after the response time (which is last member query interval * robustness variable) state - If the state is enabled, it allows the switch to be selected as an IGMP Querier (sends

IGMP query packets). It the state is disabled, then the switch cannot play the role as a querier.

Note: If the l3 router connected to the switch provide only the IGMP proxy function but does not provide the multicast routing function, then this state must be configured as disabled.

Otherwise, if the l3 router is not selected as the querier, it will not send the IGMP query packet. Since it will not send the multicast-routing protocol packet, the port will be timed out as a router port. version - Specify the version of IGMP packet that will be sent by this port. If an IGMP packet received by the interface has a version higher than the specified version, this packet will be dropped.

Only Administrator and Operator-level users can issue this command.

Example usage:

To configure the IGMP snooping querier:

DGS-3450:admin# config igmp_snooping querier vlan default query_interval 125 state enable

enable igmp_snooping

Purpose

Syntax

Description

Used to enable IGMP snooping on the switch. enable igmp_snooping {forward_mcrouter_only}

This command allows you to enable IGMP snooping on the switch. The forward mcrouter only function is disabled by default. The enable the IGMP snooping forward mcrouter only command will enable the IGMP snooping function and the forward multicast router only function.

If the forward multicast router only is enabled, the switch will forward all multicast traffic to the multicast router only. Otherwise, the switch forwards all multicast traffic to any IP router.

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

enable igmp_snooping

Parameters

Restrictions forward_mcrouter_only - If specified, the switch will learn the router port based on identification of the multicast routing protocol packet and IGMP control packet.

If not specified, the switch will learn the router port based on identification of the unicast routing protocol packet, the multicast routing protocol packet, and the IGMP control packet.

When the switch receives an IGMP report packet from a port, this port will be learned as a member port of the multicast group that the port is reported, and the router will be a default member of this multicast group. The multicast packet destined for this multicast group will be forwarded to all the members of this multicast group.

The identification of a router port will also affect the forwarding of the IGMP control packet.

When the switch receives the IGMP report packet from the client member, it will forward the packet to the router port. If the switch receives the IGMP query packet from the router port, it will forward the packet to the client member port. (If the switch itself is the querier, then it will issue the query packet to the client member port.)

Only Administrator and Operator-level users can issue this command.

Example usage:

To enable IGMP snooping on the switch:

Description

Parameters

Restrictions

Used to disable IGMP snooping on the switch. disable igmp_snooping {forward_mcrouter_only}

This command disables IGMP snooping on the switch. Disabling the IGMP snooping allows all IGMP and IP multicast traffic to flood within a given IP interface. Note that disabling IGMP snooping will also disable the forward multicast router only function.

The disable mld_snooping forward_mcrouter_only command will only disable the forward multicast router only function. forward_mcrouter_only - If specified, the switch will learn the router port based on identification of the multicast routing protocol packet and IGMP control packet.

If not specified, the switch will learn the router port based on identification of the unicast routing protocol packet, the multicast routing protocol packet, and the IGMP control packet.

The identification of a router port will also affect the forwarding of the IGMP control packet.

Purpose

Syntax

Description

Parameters

Restrictions

Used to configure an IGMP snooping multicast static group. create igmp_snooping static_group [vlan<vlan_name 32> | vlanid <vlanid_list> ] < ipaddr >

This command allows you to create an IGMP snooping static group. Member ports can be added to the static group. The static member and the dynamic member port form the member ports of a group.

The static group will only take effect when IGMP snooping is enabled on the VLAN. For those static member ports, the device needs to emulate the IGMP protocol operation to the querier, and forward the traffic destined to the multicast group to the member ports.

For a layer 3 device, the device is also responsible to route the packet destined for this specific group to static member ports.

The static member port will only affect V2 IGMP operation.

The Reserved IP multicast address 224.0.0.X must be excluded from the configured group.

The VLAN must be created first before a static group can be created. vlan_name - Specify the name of the VLAN on which the router port resides. ipaddr - Specify the multicast group IP address (for Layer 3 switch).

Only Administrator and Operator-level users can issue this command.

Example usage:

To create an IGMP snooping static group for VLAN 1, group 239.1.1.1:

DGS-3450:admin# create igmp_snooping static_group vlan vlan1 239.1.1.1

Restrictions

Used to configure an IGMP snooping multicast group static member port. config igmp_snooping static_group [vlan <vlan_name 32> | vlanid <vlanid_list> ] < ipaddr > [ add | delete] <portlist>

When a port is configured as a static member port, the IGMP protocol will not operate on this port. For example, suppose that a port is a dynamic member port learned by IGMP. If this port is configured as a static member later, then the IGMP protocol will stop operating on this port. The IGMP protocol will resume once this port is removed from static member ports.

The static member port will only affect V2 IGMP operation. vlan - Specify the name of the VLAN on which the static group resides. vlanid - Specify the ID of the VLAN on which the static group resides. ipaddr - Specify the multicast group IP address (for Layer 3 switch). add | delete - Specify to add or delete the member ports. portlist - Specify a range of ports to be configured.

You might lower this interval to reduce the amount of time it takes a router to detect the loss of the last listener of a group. state - This allows the switch to be specified as an MLD Querier (sends MLD query packets) or a Non-Querier (does not send MLD query packets). Set to enable or disable. version <value 1-2> - Specify the version of MLD packet that will be sent by this port. If a

MLD packet received by the interface has a version higher than the specified version, this packet will be dropped.

Description

Used to enable MLD snooping on the switch. enable mld_snooping {forward_mcrouter_only}

This command allows you to enable MLD snooping on the switch. The forward_mcrouter_only function is disabled by default. The enable mld_snooping forward_mcrouter_only command will enable the MLD snooping function and the forward multicast router only function.

If forward multicast router only is enabled, the switch will forward all multicast traffic to the

247

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

enable mld_snooping

Parameters

Restrictions multicast router, only. Otherwise, the switch forwards all multicast traffic to any IP router. forward_mcrouter_only - If specified, the switch will learn the router port based on identification of the multicast routing protocol packet and MLD control packet.

If not specified, the switch will learn the router port based on identification of the unicast routing protocol packet, the multicast routing protocol packet, and the MLD control packet.

When the switch receives an MLD report packet from a port, this port will be learned as a member port of the multicast group that the port is reported, and the router will be a default member of this multicast group. The multicast packet destined for this multicast group will be forwarded to all the members of this multicast group.

The identification of a router port will also affect the forwarding of the MLD control packet.

When the switch receives the MLD report packet from the client member, it will forward the packet to the router port. If the switch receives the MLD query packet from the router port, it will forward the packet to the client member port. (If the switch itself is the querier, then it will issue the query packet to the client member port.)

Only Administrator and Operator-level users can issue this command.

Example usage:

To enable MLD snooping on the switch:

DGS-3450:admin# enable mld_snooping

Command: enable mld_snooping

Success.

Description

Parameters

Restrictions

Used to disable MLD snooping on the switch. disable mld_snooping {forward_mcrouter_only}

This command disables MLD snooping on the switch. Disabling MLD snooping allows all

MLD and IP multicast traffic to flood within a given IP interface. Note that disabling MLD snooping will also disable the forward multicast router only function.

If not specified, the switch will learn the router port based on identification of the unicast routing protocol packet, the multicast routing protocol packet, and the MLD control packet.

The identification of a router port will also affect the forwarding of the MLD control packet.

config igmp_snooping data_driven_learning

Purpose

Syntax

Description

Parameters

This command is used to enable or disable the data driven learning of an IGMP snooping group. config igmp_snooping data_driven_learning [vlan_name <vlan_name> | vlanid

<vlanid_list> | all] {state [enable | disable] | aged_out [enable | disable] | expiry_time

<sec 1-65535>}(1)

This command is used to enable or disable the data driven learning of an IGMP snooping group.

When data-driven learning is enabled for the VLAN, when the switch receives the IP multicast traffic on this VLAN, an IGMP snooping group will be created. That is, the learning of an entry is not activated by IGMP membership registration, but activated by the traffic. For an ordinary IGMP snooping entry, the IGMP protocol will take care of the aging out of the entry. For a data-driven entry, the entry can be specified not to be aged out or to be aged out by the aged timer.

When data driven learning is enabled, and the data driven table is not full, the multicast filtering mode for all ports is ignored. That is, the multicast packets will be forwarded to router ports. If the data driven learning table is full, the multicast packets will be forwarded according to the multicast filtering mode.

Note that if a data-driven group is created and IGMP member ports are learned later, the entry will become an ordinary IGMP snooping entry. That is, the aging out mechanism will follow the ordinary IGMP snooping entry. vlan_name - Specify the VLAN name to be configured.

<vlan_name> - Enter the VLAN name here. vlanid - Specify the VLAN ID to be configured.

Parameters

This command is used to create a layer 3 interface. create ipif <ipif_name 12> <network_address> <vlan_name 32> { secondary | state

[enable | disable ] | proxy_arp [enable | disable] {local [enable | disable]}}

This command creates a L3 interface.

This interface can be configured with IPv4 or IPv6 address. Currently, it has a restriction. An interface can have only one IPv4 address defined. But it can have multiple IPv6 addresses defined. Thus, the multinetting configuration of IPv4 must be done through creation of a secondary interface on the same VLAN, instead of directly configuring multiple IPv4 addresses on the same interface. Configuration of IPv6 address must be done through the command config ipif.

Note that for an IPv6 case, the multicast routing protocol state in secondary IP interfaces must follow master IP interface’s state. For example, if dvmrp state in master IP interface is enabled, the secondary IP interfaces need to be the same. ipif_name - The name of the interface. network_address - IPv4 networkaddress (xxx.xxx.xxx/xx). It specifies a host address and length of network mask. vlan_name - The name of a vlan. secondary - IPv4secondary interface to be created. state - State of interface. proxy_arp - Enable/disable of proxy ARP function. It is for IPv4 function. Default: Disabled. local - This setting controls whether the system provides the proxy reply for the ARP packets destined for IP address located in the same interface as the received interface.

When proxy ARP is enabled for an interface, the system will do the proxy reply for the ARP packets destined for IP address located in a different interface. For ARP packets destined for

IP address located in the same interface, the system will check this setting to determine whether to reply.

Only Administrator and Operator-level users can issue this command. Restrictions

This command will enabled or disabled the IP directed-broadcast state of a specified interface.

An IP directed broadcast is an IP packet whose destination address is a valid broadcast address of some IP subnet, but which originates from a node that is not a part of that destination subnet.

The Switch that is not directly connected to its destination subnet and forwards an IP directed broadcast in the same way that it would forward unicast IP packets to a host on that subnet.

When a directed broadcast packet reaches a router that is directly connected to its destination subnet, and that packet is "exploded" as a broadcast on the destination subnet. It only works on layer 3 Switch. ip_directed_broadcast - Specifies the IP directed-broadcast state of the interface. enable - Enabled the IP directed-broadcast state of the interface. disable - Disabled the IP directed-broadcast state of the interface.

Only Administrator and Operator-level users can issue this command.

IP-MAC-P ORT B INDING (IMPB) C OMMANDS

IP-MAC-Port Binding (IMPB) is a security application found on edge switches which are usually directly connected to hosts. IMPB enables administrators to configure (or snoop) pairs of MAC and IP addresses that are allowed to access networks through the switch. IP-MAC-Port Binding (IMPB) binds together the network layer IP address, and the Ethernet link layer MAC address, and the receiving port, to allow the transmission of data between the layers.

The IP-MAC-Port Binding (IMPB) commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command Parameters config address_binding ip_mac ports [<portlist> | all ] { state [enable {[strict | loose] | [ipv6 | all ]} | disable {[ ipv6 | all ]}]

Description

Parameters

Restrictions

Used to configure the state of IMPB on the switch for each port. config address_binding ip_mac ports [< portlist >| all ] {state [ enable {[ strict | loose]} | disable ] | allow_zeroip [enable | disable] | forward_dhcppkt [enable | disable]} (1)

Used to configure the per port state of IMPB on the switch.

If a port has been configured as group member of an aggregated link, then the IMPB function cannot be enabled.

When the binding state is enabled for IP packets and ARP packets received by this port, the switch will check whether the IP address and MAC address matches the binding entry. If the packet does not match it will be dropped. state - This parameter configures the IMPB port state to be enabled or disabled. When the state is enabled, the port will perform the binding check. strict - Used to implement a mode of strict control. When strict control is used, all ARP and IP broadcast packets are sent to the CPU and checked for IMPB before forwarding. Packets with MAC addresses that match IMPB entries are set to dynamic state while MAC addresses with no match are set to block. All other packets are dropped. The default mode is strict if not specified. loose - Used to implement a more loose or less strict mode of control. In loose mode, ARP and IP broadcast packets are sent to the CPU for IMPB checking. Packets are forwarded unless the check finds a specified source MAC address that is blocked. Packets with MAC addresses that match IMPB entries are set to dynamic state while MAC addresses with no match are set to block. All other packets are bypassed. allow_zeroip - Specify whether to allow an ARP packet with a source IP address of 0.0.0.0. If the IP address 0.0.0.0 is not configured in the binding list and this setting is enabled, ARP packets with the source IP address of 0.0.0.0 will be allowed; If the IP address 0.0.0.0 is not configured in the binding list and this setting is set to disable, ARP packets with the source IP address of 0.0.0.0 will not be allowed. This option does not affect the IMPB ACL Mode. forward_dhcppkt - By default, DHCP packets with a broadcast DA will be flooded.

When set to disabled, the broadcast DHCP packet received by the specified port will not be forwarded.

This setting is effective when DHCP Snooping is enabled, in this case DHCP packets trapped by the CPU must be forwarded by the software.

This setting controls the forwarding behavior in this situation.

Only Administrator and Operator-level users can issue this command.

Example usage:

To enable IMPB on port 1:

When the binding check state is enabled for IP packets and ARP packets received by this port, the switch will check whether the IP address and MAC address matches the binding entry. If the packet does not match it will be dropped.

For this function, the switch can operate in ACL mode or ARP mode. In ARP mode, only ARP packets are checked for binding. In ACL mode, both ARP packets and IP packets are checked for binding. Therefore, the ACL mode provides more strict checks for packets. state - This parameter configures the IMPB port state to be enabled or disabled. When the state is enabled, the port will perform the binding check. ipv6 - For “state enable ipv6”, only the IPv6 filter table applied to the driver.

For “state enable” without specifying “ipv6”, only the IPv4 filtering table is applied to driver.

For “state enable all”, both IPv4 and IPv6 filtering tables are applied to the driver.

For example, if IPv6 is enabled, but IPv4 is disabled, only the IPv6 Snooping entry is used to create a HW filtering table, if the FDB is used as the HW filtering table, and one IPv6 entry is allowed to be forwarded, all IPv4 packets get forwarded. strict - Used to implement a mode of strict control. When strict control is used, all ARP and IP broadcast packets are sent to the CPU and checked for IMPB before forwarding. Packets with MAC addresses that match IMPB entries are set to dynamic state while MAC addresses with no match are set to block. All other packets are dropped. loose - Used to implement a more loose or less strict mode of control.

In loose mode, ARP and IP broadcast packets are sent to the CPU for IMPB checking.

Packets are forwarded unless the check finds a specified source MAC address that is blocked. Packets with MAC addresses that match IMPB entries are set to dynamic state while MAC addresses with no match are set to block. All other packets are bypassed. allow_zeroip - Specify whether to allow ARP packets with a source IP address of 0.0.0.0. If the IP address 0.0.0.0 is not configured in the binding list and this setting is enabled, ARP packets with the source IP address of 0.0.0.0 will be allowed; If the IP address 0.0.0.0 is not configured in the binding list and this setting is disabled, ARP packets with the source IP address of 0.0.0.0 will not be allowed. This option does not affect the IMPB ACL Mode. forward_dhcppkt - By default, DHCP packets with a broadcast DA will be flooded.

When set to disabled, the broadcast DHCP packet received by the specified port will not be forwarded.

This setting is effective when DHCP Snooping is enabled, in this case DHCP packets trapped by the CPU must be forwarded by the software.

This setting controls the forwarding behavior in this situation. mode - When configuring the mode of the port to be ACL mode, the switch will create an ACL access entry corresponding to the entries of the port. If the port changes to ARP mode, all

ACL access entries are deleted automatically. The default mode for a port is ARP mode. stop_learning_threshold - When the number of blocked entries exceeds the threshold, the port will stop learning new addresses. Packets with a new address will be dropped. The range is 0-500. 0 means no limit.

Only Administrator and Operator-level users can issue this command.

enable address_binding dhcp_snoop

Purpose

Syntax

Description

Used to enable DHCP snooping mode. enable address_binding dhcp_snoop {[ipv6 | all]}

By default, DHCP snooping is disabled.

If a user enables DHCP sSnooping mode, all ports which have IMPB disabled will become server ports. (The switch will learn the IP addresses through server ports (by using DHCP

Offer and DHCP ACK packets).

Note that the DHCP discover packet cannot be passed thru the user ports if the allow_zeroip function is disabled on the port.

The auto-learned IMPB entry will be mapped to a specific source port based on the MAC address learning function. This entry will be created as an ACL-mode binding entry for this specific port. Each entry is associated with a lease time. When the lease time has expires, the expired entry will be removed from the port. The auto-learned binding entry can be moved from one port to another port if the DHCP snooping function has learned that the MAC address has moved to a different port.

If a situation occurs where a binding entry learned by DHCP snooping conflicts with a statically configured entry. The binding relation has conflicted. For example, if IP A is binded to MAC X with a static configuration and suppose that the binding entry learned by DHCP snooping is that IP A is bound to MAC Y, and then it is conflict. When the DHCP snooping learned entry binds with the static configured entry, and the DHCP snooping learned entry will not be created.

In a situation where the same IMPB pair has been statically configured, the auto-learned entry will not be created. In a situation where the learned information is consistent with the

<mcastv6_address_list>] {[source_ip <ipaddr> | source_ipv6 <ip6addr>]}]

This command is used to configure the traffic to be replicated by the IP multicast VLAN replication entry. The traffic is described as a source VLAN, a list of multicast group address and an optional source IP address associated with the multicast group. Each (V, G, S) will consume one resource entry. The number of supported resource entries is project dependent. Therefore, the resource entry consumed by a replication entry is not constant and it will be determined by the number of (V, G, S) pair defined by the entry.

If the entry (V, G, S) exists in two replication entries, both will take effect. The traffic will be replicated to the destination defined by both entries.

If the entries (V, G, S) and (V, G, *) both exist in the table, the entries (V,G, S) will not take effect. name - The name of the IP multicast VLAN replication entry to be configured. vlan - The source VLAN name. vlanid - The source VLAN ID. group - Specifies the multicast IP address list. mcast_ip - The multicast IP address list. source_ip - The source IP address.

Industry is in the early stages of large scale IPv6 production deployment, and first-generation products need to make tradeoffs between available IPv6 services. Although the success of IPv6 will ultimately depend on the new applications that run over IPv6, there might be organizations or hosts within organizations that will continue to use IPv4 indefinitely.

A key part of the IPv6 design is its ability to integrate into and coexist with existing IPv4 networks. It is expected that IPv4 and IPv6 hosts will need to coexist for a substantial time during the steady migration from IPv4 to IPv6, and the development of transition strategies, tools, and mechanisms has been part of the basic IPv6 design from the start.

The IPv6 tunneling mechanism is one of the strategies for solving the transition from IPv4 to IPv6. This document describes three types of IPv6 tunnels: IPv6 Manually Configured tunnels, Automatic 6to4 Tunnels and ISATAP Tunnels.

The IPv6 Tunnel commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

This command is used to configure an IPv6 manual tunnel. config ip_tunnel manual <tunnel_name 12> {ipv6address <ipv6networkaddr> | source

<ipaddr> | destination <ipaddr>}(1)

The config ip_tunnel manual command is used to configure an existing IPv6 tunnel as an

IPv6 manual tunnel on the switch. If this tunnel has previously been configured in another mode, the tunnel’s information will still exist in the database. However, whether the tunnel’s former information is invalid or not, will depend on the current mode.

IPv6 Manual tunnels are simple point-to-point tunnels that can be used within a site or between sites.

< tunnel_name 12> - IPv6 Tunnel interface name, maximum of 12 characters. ipv6address <ipv6networkaddr> - The IPv6 address assigned to this IPv6 tunnel interface.

IPv6 processing would be enabled on this IPv6 tunnel interface when an IPv6 address is configured. This IPv6 address is not connected with tunnel source or destination IPv4 address. source <ipaddr> - The source IPv4 address of this IPv6 tunnel interface. It is used as the source address for packets in this IPv6 tunnel. destination <ipaddr> - The destination IPv4 address of this IPv6 tunnel interface.

Syntax

Description

Parameters

Restrictions

Used to configure an IPv6 6to4 tunnel. config ip_tunnel 6to4 <tunnel_name 12> {ipv6address <ipv6networkaddr> | source

<ipaddr >}(1)

The config ip_tunnel 6to4 command is used to configure an existing IPv6 tunnel as an IPv6

6to4 tunnel on the switch. If this tunnel has previously been configured in another mode, the tunnel’s information will still exist in the database. However, whether the tunnel’s former information is invalid or not will depend on the current mode. A maximum of one IPv6 6to4 tunnel can exist on the system.

IPv6 6to4 tunnels are point-to-multipoint tunnels that can be used to connect isolated IPv6 sites. Each IPv6 site has at least one connection to a shared IPv4 network and this IPv4 network could be the global Internet or a corporate backbone. The key requirement is that each site has a globally unique IPv4 address, which is used to construct a 48-bit globally unique 6to4 IPv6 prefix (It starts with the prefix 2002::/16).

<tunnel_name 12> - IPv6 Tunnel interface name, maximum of 12 characters. ipv6address <ipv6networkaddr> - The IPv6 address assigned to this IPv6 tunnel interface.

IPv6 processing would be enabled on this IPv6 tunnel interface when an IPv6 address is configured. The 32 bits following the initial 2002::/16 prefix correspond to an IPv4 address assigned to the tunnel source. source <ipaddr> - The source IPv4 address of this IPv6 tunnel interface. It is used as the source address for packets in this IPv6 tunnel. The tunnel destination IPv4 address is extracted from the remote tunnel endpoint’s IPv6 6to4 address that starts with the prefix

2002::/16.

Only Administrator and Operator-level users can issue this command.

Example usage:

To configure an IPv6 6to4 tunnel (Tunnel name is “tn2”, Tunnel source IPv4 address is 10.0.0.1, Tunnel IPv6 address is

The config ip_tunnel isatap command is used to configure an existing IPv6 tunnel as an IPv6

ISATAP tunnel on the switch. If this tunnel has previously been configured in another mode, the tunnel’s information will still exist in the database. However, whether the tunnel’s former information is invalid or not will depend on the current mode. IPv6 ISATAP tunnels are pointto-multipoint tunnels that can be used to connect systems within a site. An IPv6 ISATAP address is a well-defined unicast address that includes a 64-bit unicast IPv6 prefix (it can be link local or global prefixes), a 32-bit value 0000:5EFE and a 32-bit tunnel source IPv4 address.

<tunnel_name 12> - IPv6 Tunnel interface name, maximum of 12 characters. ipv6address <ipv6networkaddr> - The IPv6 address assigned to this IPv6 tunnel interface.

Purpose

Syntax

Description

Parameters

Used to configure settings for LACP compliant ports. config lacp_ports <portlist> mode [active | passive]

This command is used to configure ports that have been previously designated as LACP ports

(see create link_aggregation ).

<portlist>

−

Specifies a port or range of ports to be configured. The beginning and end of the port list range are separated by a dash. Non-contiguous portlist entries are separated by a comma. (ex: 1-3,7-9) mode – Select the mode to determine if LACP ports will process LACP control frames.

• active – Active LACP ports are capable of processing and sending LACP control frames. This allows LACP compliant devices to negotiate the aggregated link so the group may be changed dynamically as needs require. In order to utilize the ability to change an aggregated port group, that is, to add or subtract ports from the group, at least one of the participating devices must designate LACP ports as active. Both devices must support LACP.

• passive – LACP ports that are designated as passive cannot process LACP control frames. In order to allow the linked port group to negotiate adjustments and make changes dynamically, at one end of the connection must have “active” LACP ports

(see above).

Restrictions Only Administrator and Operator-level users can issue this command.

Example usage:

To configure LACP port mode settings:

DGS-3450:admin# config lacp_port 1:1-1:12 mode active

The Link Layer Discovery Protocol (LLDP) commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

The Link Layer Discovery Protocol (LLDP) specified in this standard allows stations attached to an 802 LAN to advertise to other stations attached to the same 802 LAN the connectivity and management information necessary to identify to those management entities the station's point of attachment to the 802 LAN. The information distributed via this protocol is stored by its recipients in a standard management information base (MIB), making it possible for the information to be accessed by a network management system (NMS) using a management protocol such as the Simple Network

Management Protocol (SNMP)

Description

Parameters

Restrictions config mac_based_access_control ports [<portlist> | all] {state [enable | disable] | mode [port_based | host_based] | aging_time [infinite | <min 1-1440>] | [block_time | hold_time ] [infinite|<sec 1-300>] | max_users [<value 1-4000> | no_limit]}(1)

This command allows configures MAC-based Access Control port’s setting.

When the MAC-based Access Control function is enabled for a port and the port is not a

MAC-based Access Control guest VLAN member, the user who is attached to this port will not be forwarded unless the user passes the authentication. A user that does not pass the authentication will not be serviced by the switch. If the user passes the authentication, the user will be able to forward traffic operated under the assigned VLAN.

When the MAC-based Access Control function is enabled for a port, and the port is a MACbased Access Control guest VLAN member, the port(s) will be removed from the original

VLAN(s) member ports, and added to MAC-based Access Control guest VLAN member ports. Before the authentication process starts, the user is able to forward traffic under the guest VLAN. After the authentication process, the user will be able to access the assigned

VLAN.

If the port authorize mode is port based mode, when the port has been moved to the authorized VLAN, the subsequent users will not be authenticated again. They will operate in the current authorized VLAN. If the port authorize mode is host based mode, then each user will be authorized individually and be capable of getting its own assigned VLAN. ports - Specifies a range of ports for configuring the MAC-based Access Control function parameters. state - Specifies whether the port’s MAC-based Access Control function is enabled or disabled. mode - See below: port_based - Port based means that all users connected to a port share the first authentication result. host_based - Host based means that each user has its own authentication result. If the Switch does not support MAC-based VLANs, the switch will not allow the host based option for ports that are in guest VLAN mode. aging_time - A time period during which an authenticated host will be kept in an authenticated state. When the aging time has timed-out, the host will be moved back to unauthenticated state. If the aging time is set to infinite, it means that authorized clients will not be aged out automatically. block_time - If a host fails to pass the authentication, the next authentication will not start within the block time unless the user clears the entry state manually. If the block time is set to

0, it means do not block the client that failed authentication. block_time – Specify the block time here. infinite – Specify to set the time to infinite. max_users - Specify maximum number of users per port. The range is 1 to 4000. The default value is 128.

Only Administrator and Operator-level users can issue this command.

Description

Parameters

Restrictions

Used to display the MAC-based Access Control authentication status. show mac_based_access_control auth_state ports <portlist>

This command is used to display the MAC-based Access Control authentication status.

<portlist> - Display authentication status by specific port.

If not specified port(s), it will display all of MAC-based Access Control ports authentication status.

None.

Example usage:

Suppose that port 1 is in host based mode:

•

MAC 00-00-00-00-00-01 is authenticated without a VLAN assigned (may be the specified target VLAN does not exist or the target VLAN has not been specified at all), the ID of the RX VLAN will be displayed (RX VLAN ID is

4004 in this example).

•

MAC 00-00-00-00-00-02 is authenticated with a target VLAN assigned, the ID of the target VLAN will be displayed (target VLAN ID is 1234 in this example).

•

MAC 00-00-00-00-00-03 fails to pass authentication, the VID field will be shown as “-”, indicating that packets with SA 00-00-00-00-00-03 will be dropped no matter which VLAN these packets are from.

•

MAC 00-00-00-00-00-04 attempts to start authentication, the VID field will be shown as “-“until authentication completes.

Suppose that port 2 is in port based mode:

•

MAC 00-00-00-00-00-10 is the host which causes port 2 to pass authentication; the MAC address is followed by

“(P)” to indicate port based mode authentication.

Suppose that port 3 is in port based mode:

•

MAC 00-00-00-00-00-20 attempts to start authentication, the MAC address is followed by “(P)” to indicate port based mode authentication.

•

MAC 00-00-00-00-00-21 fails to pass authentication, the MAC address is followed by “(P)” to indicate port based mode authentication.

NOTE: In port-based mode, the VLAN ID field is displayed in the same way as host based mode.

Each command is listed, in detail, in the following sections.

config mirror port

Purpose

Syntax

Description

Parameters

Restrictions

Used to configure a mirror port

− source port pair on the switch. Traffic from any source port to a target port can be mirrored for real-time analysis. A logic analyzer or an RMON probe then can be attached to study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port traffic, please note that the target port must be configured in the same VLAN and operates at the same speed as the source port. If the target port is operating at a lower speed, the source port will be forced to drop its operating speed to match that of the target port. config mirror port <port> {[add | delete] source ports <portlist> [rx | tx | both]}

The config mirror command allows a range of ports to have all of their traffic also sent to a destination port

− where a network sniffer or other device can monitor the network traffic. In addition, you can specify that only traffic received by or sent by or both are mirrored to the target port.

This command used for single mirror session configuration primarily. If used for multiple session configurations, it configures the parameters on mirror group 1. If group 1 not exist, create group 1 firstly, and than configure the parameters on group 1. port - The port that will receive the packets duplicated at the mirror port. add - The mirror entry to be added. delete - The mirror entry to be deleted. portlist - The port that will be mirrored. All packets entering and leaving the source port can be duplicated in the mirror port. rx - Allows the mirroring packets received (flowing into) the port or ports in the port list. tx - Allows the mirroring packets sent (flowing out of) the port or ports in the port list. both - Mirrors all the packets received or sent by the port or ports in the port list.

Only Administrator and Operator-level users can issue this command.

Description

Parameters

Restrictions

Used to create a multicast VLAN. create igmp_snooping multicast_vlan <vlan_name 32> <vlanid 2-4094> { remap_priority [ <value 0-7> | none ] { replace_priority } }

The create igmp_snooping command creates a multicast VLAN and implements relevant parameters as specified. More than one multicast VLANs can be configured. The maximum number of configurable VLANs is project dependent.

Newly created IGMP snooping must use a unique VLAN ID and name, i.e. they cannot use the VLAN ID or name of any existing 802.1q VLAN.

Also keep in mind the following conditions:

•

Multicast VLANs cannot be configured or displayed using 802.1Q VLAN commands.

•

An IP interface cannot be bound to a multicast VLAN.

•

The multicast VLAN snooping function co-exists with the 802.1q VLAN snooping function. vlan_name - The name of the multicast VLAN to be created. Each multicast VLAN is given a name that can be up to 32 characters. vlanid - The VLAN ID of the multicast VLAN to be created. The range is 2 - 4094. remap_priority - The remap priority (0 to 7) to be associated with the data traffic to be forwarded on the multicast VLAN. If none is specified, the packet’s original priority will be used. The default setting is none. replace_priority - Specify that packet’s priority will be changed by the switch, based on the remap priority. This flag will only take effect when the remap priority is set.

Only Administrator and Operator-level users can issue this command.

Description

Parameters

Restrictions

Used to configure the parameters of a specific IGMP snooping multicast VLAN. config igmp_snooping multicast_vlan <vlan_name 32> {member_port <portlist> |

[source_port <portlist> | untag_source_port <portlist>] | tag_member_port <portlist> | state [enable | disable] | replace_source_ip <ipaddr> | remap_priority [<value 0-7> | none] {replace_priority}}

The config igmp_snooping multicast_vlan command allows you to add member ports and source ports to a list of multicast VLAN member ports. Member ports automatically become untagged members of the multicast VLAN and source ports automatically become tagged members of the multicast VLAN. If the port list of an existing multicast VLAN is changed without specifying add or delete, the newly added port list replaces the existing port list. A member port list cannot overlap with a source port list of the same multicast VLAN. However, member ports of one multicast VLAN are allowed to overlap with member ports on a different multicast VLAN.

A multicast VLAN must first be created using the create igmp_snooping multicast_vlan command before the multicast VLAN can be configured. vlan_name - The name of the multicast VLAN to be configured. Can be up to 32 characters. member_port - A member port or range of member ports to be added to the multicast VLAN.

The specified range of ports will become untagged members of the multicast VLAN. source_port - A port or range of ports to be added to the multicast VLAN. untag_source_port - Specify the source port or range of source ports as untagged members of the multicast VLAN. The PVID of the untagged source port is automatically changed to the multicast VLAN. Source ports must be either tagged or untagged for any single multicast

VLAN, i.e. both types cannot be members of the same multicast VLAN. tag_member_port - A member port or range of member ports to be added to the multicast

VLAN. The specified range of ports will become tagged members of the multicast VLAN. state - Used to specify if the multicast VLAN for a chosen VLAN should be enabled or disabled. replace_source_ip - Before forwarding the report packet sent by the host, the source IP address in the join packet must be replaced by this IP address. remap_priority - The remap priority value (0 to 7) to be associated with the data traffic to be forwarded on the multicast VLAN. If none is specified, the packet’s original priority is used.

The default setting is none. replace_priority - Specify that the packet priority will be changed to the remap_priority, but only if remap_priority is set.

Only Administrator and Operator-level users can issue this command.

Used to configure the multicast group learned with the specific multicast VLAN. The following two cases can be considered for examples:

Case 1- The multicast group is not configured, multicast VLANs do not have any member ports overlapping and the join packet received by the member port is learned on only the multicast VLAN that this port is a member of.

Case 2-The join packet is learned with the multicast VLAN that contains the destination multicast group. If the destination multicast group of the join packet cannot be classified into any multicast VLAN to which this port belongs, then the join packet will be learned on the natural VLAN of the packet. vlan_name - The name of the multicast VLAN to be configured. Each multicast VLAN is given a name of up to 32 characters. add - Used to associate a profile to a multicast VLAN. delete - Used to de-associate a profile from a multicast VLAN.

Use to create the switch’s NLB multicast FDB entry. create nlb multicast_fdb [<vlan_name 32> | vlanid <vlanid>] <macaddr>

The create nlb multicast_fdb command creates a NLB multicast FDB entry. The number of supported entries is project dependent.

The network load balancing command set is used to support the Microsoft server load balancing application where multiple servers can share the same IP address and MAC address. The requests from clients will be forwarded to all servers, but will only be processed by one of them. The server can work in multicast mode. In multicast mode, the client use the multicast MAC address as the destination MAC to reach the server. Regarding of the mode, this destination Mac is the named the shared MAC. The server uses its own MAC address

(rather than the shared MAC) as the source MAC address of the reply packet.

The NLB multicast FDB entry will be mutual exclusive with the L2 multicast entry. vlan_name - Specify the VLAN of the NLB multicast FDB entry to be created. vlanid <vlanid> - Specify the VLAN by the VLAN ID.

<macaddr> - Specify the MAC address of the NLB multicast FDB entry to be created.

Description

Parameters

Restrictions

Used to configure the parameters for the POE system-wise function. config poe system {[units <unitlist> |all]} {power_limit <value m-n> | power_disconnect_method [deny_next_port | deny_low_priority_port] | legacy_pd

[enable | disable]}

Configure the parameters for the whole PoE system. units - Specified the units that will be configured. If no specified units, all supported PoE units in the system will be configured. power_limit - Configure the power budget of PoE system. The range of value which can be specified is determined by the system. Normally, the minimum setting is 37 W and the maximum setting is 370 W. The actual range will depend on power supply capability. power_disconnect_method - Configure the disconnection method that will be used when the power budget is running out. When the system attempts to supply power to a new port, if the power budget is insufficient to do this, PoE controller will initiate port disconnection procedure to prevent overloading the power supply. The controller uses one of the following two ways to perform the disconnection procedure. deny_next_port - The port with max port number will be denied regardless of its priority.

Note: that if the disconnect_method is set to deny_next_port, then the power provision will not utilize the system’s maximum power. There is a 19W safe margin. That is, when the system has only 19W remaining, this power cannot be utilized. deny_low_priority_port - If there are ports that have been supplied power that have a priority lower than the new port, the port with the lowest priority will be disconnected. This process will stop until enough power is released for the new port.

Note: that if the disconnect_method is set to deny_low_priority_port, then the power provision can utilize the system’s maximum power. legacy_pd - Configure legacy PDs detection status, enable for support, if set to disable, can’t detect legacy PDs signal.

Only Administrator and Operator-level users can issue this command.

Parameters

Restrictions

Used to configure the PoE port settings. config poe ports [all | <portlist>] {state [enable | disable] | [time_range <range_name

32> | clear_time_range] | priority [critical | high | low] | power_limit [class_0 | class_1 | class_2 | class_3 | user_define <value m - n>]}

Configure the PoE port settings. portlist - Specified the list of ports whose setting is under configuration. all - Specifies that all ports will be used. state - When the state is set to disable, power will not be supplied to the powered device connected to this port. time_range - Specifies the time range that applies to the port of the POE. If time range is configured, the power can only be supplied during the period specified by time range. clear_time_range - Remove the time range. priority - Port priority determines the priority the system attempts to supply the power to port.

There are three levels of priority that can be selected, critical, high, and low. When multiple ports happen to have the same level of priority, the port ID will be used to determine the priority. The lower port ID has higher priority. The setting of priority will affect the ordering of supplying power. Whether the disconnect_method is set to deny_low_priority_port, priority of port will be used by the system to manage to supply power to ports. power_limit - Configure the per-port power limit. If a port exceeds its power limit, it will be shut down.

Based on 802.3af, there are 5 kinds of PD classes, class 0, class 1, class 2, and class 3. The power consumption ranges for them are 0.44~12.95W, 0.44~3.84W, 3.84~6.49W,

6.49~12.95W, and 12.95~ 29.5W, respectively.

The five pre-defined settings are for users’ convenience: The following is the power limit applied to the port for these four classes. For each class, the power limit is a little more than the power consumption range for the class. This takes the factor of the power loss on cable into account. Thus, the following are the typical values defined by the chip vendor.

Class_0 : 15400mW class_1 : 4000mW class_2 : 7000mW clase_3 : 15400mW

Other than these four pre-defined settings, users can directly specify any value that the chip supported, Normally, the minimum setting is 1000mW, and the maximum setting is 15400mW for 802.3af and >=35000mW for 802.3at.

Only Administrator and Operator-level users can issue this command.

Note: PD means powered device, for example, Web Cam, IP phone, wireless AP, etc.

PSE means power sourcing equipment, for example, our PoE switch.

P ROTOCOL VLAN G ROUP C OMMANDS

For bridges that implement Port-and-Protocol-based VLAN classification, the VID associated with an Untagged or

Priority-tagged Frame is determined based on the Port of arrival of the frame into the bridge and on the protocol identifier of the frame. If there is no protocol VLAN configured on the ingress port, all the untagged packets incoming on the port will be classified into PVID VLAN. This classification mechanism requires defining the protocol groups which specified frame type and protocol value to match for. A protocol group can be bound to a port and given a VLAN ID. If the incoming untagged packet matches the protocol group the VLAN ID will be assigned. A port can bind with multiple protocol groups.

This allows untagged packets be classified into different VLANs based on packet content. The same protocol group can be assigned to multiple ports with different VLAN ID assigned, i.e. the same protocol can be given different VLAN ID through binding to different ports.

The Protocol VLAN Group commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command Parameter create dot1v_protocol_group config dot1v_protocol_group delete dot1v_protocol_group show dot1v_protocol_group config port dot1v show port dot1v group_id <id> group_id <id> [add | delete] protocol [ethernet_2 | ieee802.3_snap | ieee802.3_llc] <protocol_value> group_id <id>

The specification of min_rate and max_rate are effective regardless of whether the queue is operating in strict mode or in WRR mode. ports <portlist> - Specifies a range of ports to be configured. all - To set all ports in the system, you may use the “all” parameter. If no parameter is specified, the system will set all ports.

<cos_id_list 0-6> - Specifies a list of priority queues. The priority queue number is ranged from 0 to 6. min_rate - Specifies that one of the parameters below (no_limit or 64-10000000) will be applied to the minimum rate, which the above specified class will be allowed to receive packets at. no_limit - Specifies that there will be no limit on the rate of packets received by the class specified above.

<value 64-10000000> - Specifies the packet limit, in Kbps, that the above ports will be allowed to receive.

R EMOTE C OPY P ROTOCOL (RCP) C OMMANDS

RCP is a UNIX Remote Shell service which allows files to be copied between a server and client. RCP is an application that operates above the TCP protocols, and uses port number 514 as the TCP destination port.

The RCP application uses client server architecture and the client can be any machine running the RCP client application.

A Switch that supports the RCP client allows users to copy firmware images, configurations and log files between the

Switch and RCP Server.

Switches that do not support a file system should still be able to run an RCP client to copy firmware images, configurations and logs between the switch and RCP server.

The Remote Copy Protocol (RCP) commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command config rcp server config rcp server clear show rcp server download firmware_fromRCP download cfg_fromRCP upload cfg_toRCP upload log_toRCP upload attack_log_toRCP

enable rspan

Purpose

Syntax

Description

Parameters

Restrictions

Used to enable the RSPAN globally. enable rspan

This command controls the RSPAN function.

The purpose of the RSPAN function is to mirror packets to a remote switch.

A packet travels from the switch where the monitored packet is received, passing through the intermediate switch, and then to the switch where the sniffer is attached. The first switch is also named the source switch.

To make the RSPAN function work, the RSPAN VLAN source setting must be configured on the source switch. For the intermediate and the last switch, the RSPAN VLAN redirect setting must be configured.

Note: RSPAN VLAN mirroring will only work when RSPAN is enabled (when one RSPAN

VLAN has been configured with a source port).

The RSPAN redirect function will work when RSPAN is enabled and at least one RSPAN

VLAN has been configured with redirect ports.

None.

Only Administrator and Operator-level users can issue this command.

Used by the intermediate or last switch to configure the output port for the RSPAN mirrored packet. config rspan vlan [vlan_name <vlan_name> | vlan_id <vlanid 1-4094>] redirect [add | delete] port <port>

This command is used by the intermediate or last switch to configure the output port of the

RSPAN VLAN packets.

The redirect command makes sure that the RSPAN VLAN packets can egress to the redirect ports. In addition, to this redirect command, the VLAN setting must be correctly configured to make the RSPAN VLAN work correctly. That is, for the intermediate switch, the redirect port must be tagged member port of RSPAN VLAN. For the last switch, the redirect port must be either be a tagged member port or an untagged member port of the RSPAN VLAN based on the users’ requirements. If untagged membership is specified, the RSPAN VLAN tag will be removed.

The redirect function will only work when RSPAN is enabled.

Multiple RSPAN VLANs can be configured with the redirect setting at the same time.

A RSPAN VLAN can be configured with the source setting and the redirect setting at the same time. vlan - See below: vlan_name - Specify the RSPAN VLAN by VLAN name. vlan_id - Specify the RSPAN VLAN by VLAN ID. redirect - Specify output portlist for the RSPAN VLAN packets. If the redirect port is a Link

Aggregation port, there will perform the Link Aggregation behavior for RSPAN packets.

Only Administrator and Operator-level users can issue this command.

S AFEGUARD E NGINE C OMMANDS

Periodically, malicious hosts on the network will attack the Switch by utilizing packet flooding (ARP Storm) or other methods. These attacks may increase the CPU utilization beyond its capability. To alleviate this problem, the Safeguard

Engine function was added to the Switch’s software.

The Safeguard Engine can help the overall operability of the Switch by minimizing the workload of the Switch while the attack is ongoing, thus making it capable to forward essential packets over its network in a limited bandwidth. When the

Switch either (a) receives too many packets to process or (b) exerts too much memory, it will enter an Exhausted mode.

When in this mode, the Switch will perform the following tasks to minimize the CPU usage:

1. It will limit bandwidth of receiving ARP packets. The user may implement this in two ways, by using the config safeguard_engine command. a. When strict is chosen, the Switch will stop receiving ARP packets not destined for the Switch. This will eliminate all unnecessary ARP packets while allowing the essential ARP packets to pass through to the

Switch’s CPU. b. When fuzzy is chosen, the Switch will minimize the ARP packet bandwidth received by the switch by adjusting the bandwidth for all ARP packets, whether destined for the Switch or not. The Switch uses an internal algorithm to filter ARP packets through, with a higher percentage set aside for ARP packets destined for the Switch.

2. It will limit the bandwidth of IP packets received by the Switch. The user may implement this in two ways, by using the config safeguard_engine command. a. When strict is chosen, the Switch will stop receiving all unnecessary broadcast IP packets, even if the high CPU utilization is not caused by the high reception rate of broadcast IP packets. b. When fuzz y is chosen, the Switch will minimize the IP packet bandwidth received by the Switch by adjusting the bandwidth for all IP packets, by setting a acceptable bandwidth for both unicast and broadcast IP packets. The Switch uses an internal algorithm to filter IP packets through while adjusting the bandwidth dynamically.

IP packets may also be limited by the Switch by configuring only certain IP addresses to be accepted. This method can be accomplished through the CPU Interface Filtering mechanism explained in the previous section. Once the user configures these acceptable IP addresses, other packets containing different IP addresses will be dropped by the Switch, thus limiting the bandwidth of IP packets. To keep the process moving fast, be sure not to add many conditions on which to accept these acceptable IP addresses and their packets, this limiting the CPU utilization.

Once in Exhausted mode, the packet flow will decrease by half of the level that caused the Switch to enter Exhausted mode. After the packet flow has stabilized, the rate will initially increase by 25% and then return to a normal packet flow.

NOTICE: When the Safeguard Engine is enabled, the Switch will allot bandwidth to various traffic flows (ARP, IP) using the FFP (Fast Filter Processor) metering table to control the CPU utilization and limit traffic. This may limit the speed of routing traffic over the network.

The Safeguard Engine commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command config safeguard_engine show safeguard_engine

Parameters

{state [enable | disable] | utilization {rising <value 20-100> | falling <value 20-

Use this command to configure Safeguard Engine to minimize the effects of an ARP storm. state [enable | disable] – Select the running state of the Safeguard Engine function as enable or disable. utilization – Select this option to trigger the Safeguard Engine function to enable based on the following determinates:

• rising <value 20-100> – The user can set a percentage value of the rising CPU utilization which will trigger the Safeguard Engine function. Once the CPU utilization rises to this percentage, the Safeguard Engine mechanism will initiate.

• falling <value 20-100> – The user can set a percentage value of the falling

CPU utilization which will trigger the Safeguard Engine function to cease. Once the CPU utilization falls to this percentage, the Safeguard Engine mechanism will shut down. trap_log [enable | disable] – Choose whether to enable or disable the sending of messages to the device’s SNMP agent and switch log once the Safeguard Engine has been activated by a high CPU utilization rate. mode - Used to select the type of Safeguard Engine to be activated by the Switch when the CPU utilization reaches a high rate. The user may select:

• strict – If selected, this function will stop accepting all ARP packets not intended for the Switch, and will stop receiving all unnecessary broadcast IP packets, until the storm has subsided.

• fuzzy – If selected, this function will instruct the Switch to minimize the IP and

ARP traffic flow to the CPU by dynamically allotting an even bandwidth to all traffic flows.

Only Administrator and Operator-level users can issue this command.

S ECURE S OCKETS L AYER (SSL) C OMMANDS

Secure Sockets Layer or SSL is a security feature that will provide a secure communication path between a host and client through the use of authentication, digital signatures and encryption. These security functions are implemented through the use of a ciphersuite, which is a security string that determines the exact cryptographic parameters, specific encryption algorithms and key sizes to be used for an authentication session and consists of three levels:

1. Key Exchange: The first part of the ciphersuite string specifies the public key algorithm to be used. This Switch utilizes the Rivest Shamir Adleman (RSA) public key algorithm and the Digital Signature Algorithm (DSA), specified here as the DHE_DSS Diffie-Hellman (DHE) public key algorithm. This is the first authentication process between client and host as they “exchange keys” in looking for a match and therefore authentication to be accepted to negotiate encryptions on the following level.

2. Encryption: The second part of the ciphersuite that includes the encryption used for encrypting the messages sent between client and host. The Switch supports two types of cryptology algorithms: a. Stream Ciphers – There are two types of stream ciphers on the Switch, RC4 with 40-bit keys and RC4 with 128-bit keys. These keys are used to encrypt messages and need to be consistent between client and host for optimal use. b. CBC Block Ciphers – CBC refers to Cipher Block Chaining, which means that a portion of the previously encrypted block of encrypted text is used in the encryption of the current block. The Switch supports the

3DES_EDE encryption code defined by the Data Encryption Standard (DES) to create the encrypted text.

3. Hash Algorithm : This part of the ciphersuite allows the user to choose a message digest function which will determine a Message Authentication Code. This Message Authentication Code will be encrypted with a sent message to provide integrity and prevent against replay attacks. The Switch supports two hash algorithms, MD5

(Message Digest 5) and SHA (Secure Hash Algorithm).

These three parameters are uniquely assembled in four choices on the Switch to create a three layered encryption code for secure communication between the server and the host. The user may implement any one or combination of the ciphersuites available, yet different ciphersuites will affect the security level and the performance of the secured connection. The information included in the ciphersuites is not included with the Switch and requires downloading from a third source in a file form called a certificate . This function of the Switch cannot be executed without the presence and implementation of the certificate file and can be downloaded to the Switch by utilizing a TFTP server. The Switch supports SSLv3 and TLSv1. Other versions of SSL may not be compatible with this Switch and may cause problems upon authentication and transfer of messages from client to host.

This command will enable SSL on the Switch by implementing any one or combination of listed ciphersuites on the Switch. Entering this command without a parameter will enable the SSL status on the Switch. Enabling SSL will disable the web-manager on the Switch. ciphersuite – A security string that determines the exact cryptographic parameters, specific encryption algorithms and key sizes to be used for an authentication session. The user may choose any combination of the following:

•

RSA_with_RC4_128_MD5 – This ciphersuite combines the RSA key exchange, stream cipher RC4 encryption with 128-bit keys and the MD5 Hash Algorithm.

•

RSA_with_3DES_EDE_CBC_SHA – This ciphersuite combines the RSA key exchange, CBC Block Cipher 3DES_EDE encryption and the SHA Hash Algorithm.

•

DHE_DSS_with_3DES_EDE_CBC_SHA – This ciphersuite combines the DSA Diffie

Hellman key exchange, CBC Block Cipher 3DES_EDE encryption and SHA Hash

Algorithm.

•

RSA_EXPORT_with_RC4_40_MD5 – This ciphersuite combines the RSA Export key exchange, stream cipher RC4 encryption with 40-bit keys.

The ciphersuites are enabled by default on the Switch, yet the SSL status is disabled by default. Enabling SSL with a ciphersuite will not enable the SSL status on the Switch.

Restrictions Only Administrator and Operator-level users can issue this command.

Example usage:

To enable SSL on the Switch for all ciphersuites:

NOTE: Enabling SSL on the Switch will enable all ciphersuites. To utilize a particular ciphersuite, the user must eliminate other ciphersuites by using the disable ssl command along with the appropriate ciphersuites.

NOTE: Enabling the SSL function on the Switch will disable the port for the web manager (port

80). To log on to the web based manager, the entry of your URL must begin with https://. (ex. https://10.90.90.90)

config ssl cachetimeout

Purpose

Syntax

Description

Parameters

Restrictions

Used to configure the SSL cache timeout. config ssl cachetimeout <value 60-86400>

This command will set the time between a new key exchange between a client and a host using the SSL function. A new SSL session is established every time the client and host go through a key exchange. Specifying a longer timeout will allow the SSL session to reuse the master key on future connections with that particular host, therefore speeding up the negotiation process.

<value 60-86400> – Enter a timeout value between 60 and 86400 seconds to specify the total time an SSL key exchange ID stays valid before the SSL module will require a new, full SSL negotiation for connection. The default cache timeout is 600 seconds

Only Administrator and Operator-level users can issue this command.

−

Configure all ports on the Switch.

<portlist>

−

Specifies a port or range of ports to be configured. The beginning and end of the port list range are separated by a dash. medium_type [fiber | copper] – This applies only to the Combo ports. If configuring the Combo ports this defines the type of transport medium used. speed – Allows the user to adjust the speed for a port or range of ports. The user has a choice of the following:

• auto

−

Enables auto-negotiation for the specified range of ports.

•

[10 | 100 | 1000]

−

Configures the speed in Mbps for the specified range of ports. Gigabit ports are statically set to 1000 and cannot be set to slower speeds.

•

[half | full]

−

Configures the specified range of ports as either full-duplex or half-duplex.

•

[master | slave] – The master setting (1000M/Full_M) will allow the port to advertise capabilities related to duplex, speed and physical layer type. The master setting will also determine the master and slave relationship between the two connected physical layers. This relationship is necessary for establishing the timing control between the two physical layers.

The timing control is set on a master physical layer by a local source. The slave setting

(1000M/Full_S) uses loop timing, where the timing comes form a data stream received from the master. If one connection is set for 1000M/Full_M, the other side of the connection must be set for 1000M/Full_S. Any other configuration will result in a link down status for both ports. flow_control [enable | disable] – Enable or disable flow control for the specified ports. learning [enable | disable]

−

Enables or disables the MAC address learning on the specified range of ports. state [enable | disable]

−

Enables or disables the specified range of ports. If the specific ports are in an error-disabled state configuring their state to enable will recover these ports from disabled to enabled state. description <desc 1-32>

−

Enter an alphanumeric string of no more than 32 characters to describe a selected port interface. clear_description

−

Enter this command to clear the port description of the selected port(s).

Displays the attack log messages. show attack_log {unit <unit_id 1-n>} {index <value_list>}

Displays the attack log messages. The attack log message refers to log messages driven by modules such as DOS and the IP-MAC-port binding module. This type of log message may generate a large amount of messages and quickly cause the system to run out of system log storage. Therefore, for this type of log messages only the first log that is generated each minute can be stored in the system log, with the rest of them being stored in a separate table named attack log.

When the attack log is empty, the prompt message, “Log is empty,” will be displayed. unit - The attack log messages on the specified unit will be displayed.

If unit ID is specified, then this unit will be referred to as the master unit. index - The list of index numbers of the entries that need to be displayed. For example, show attack_log index 1-5 will display the attack log messages from 1 to 5.

traceroute

Purpose

Syntax

Description

Parameters

Restrictions

This command is used to trace the routed path between the switch and a destination end station. traceroute [<ipaddr> | <domain_name 255>] {ttl <value 1-60> | port <value 30000-

64900> | timeout <sec 1-65535> | probe <value 1-9>}

To track the route of an IP packet, traceroute launches UDP probe packets with a small TTL

(time to live) and then listens for an ICMP "time exceeded" reply from a gateway. Probes start with a TTL of one and increase by one until either an ICMP "port unreachable" is returned, indicating that the packet reached the host, or the maximum number of hops is exceeded. At each TTL setting, one probe packet is launched (the number can be changed by specifying the parameter “probe”) and traceroute prints a line showing the round trip time and the address of the gateway of each probe, or time out of each probe. If there is no response within the 5 seconds timeout interval, an asterisk (*) is printed for that probe. ipaddr - IP address of the destination end station.

<domain_name 255> - The domain name of the destination end station. ttl <value 1-60> - The time to live value of the trace route request. This is the maximum number of routers that a trace route packet can cross, while seeking the network path between two devices. The range for the TTL is 1 to 60 hops. port <value 30000–64900> - Specify the destination UDP port number. The UDP port range is from 30000 to 64900. timeout <sec 1-65535> - Define the timeout period while waiting for a response from the remote device. A value of 1 to 65535 seconds can be specified. The default is 5 seconds. probe <value 1-9> - Specify the number of probe packets for each TTL. The default is 1.

Note: The probe will be terminated once the destination is reached.

Only Administrator and Operator-level users can issue this command.

T RAFFIC C ONTROL C OMMANDS

There are two modes used for packet storm control on the Switch, Drop mode and Shutdown mode. Drop mode is hardware-based (chip-based) and Shutdown mode is a function of software. The two modes are incompatible with each other, therefore it is necessary to determine which method is best suited to the network environment where it is used.

Drop mode

The Drop mode storm control function is used to configure three chip-based hardware tables for state and a single threshold value (threshold value is the same for all three tables). If the threshold value is exceeded on a port, the Switch will drop all packets on the port. In Drop mode, some parameters such as “time interval” and “count down,” as well as the

CLI command, “config traffic control auto_recover_time” are software-based functions and therefore not applicable for

Drop mode traffic control.

Shutdown mode

Shutdown mode is a software-based storm control function. When shutdown mode is used, the state of the hardware tables used for Drop mode are set to disable. Shutdown mode does not support DLF storm control. All configurations except the port state are saved in the software table. The CPU receives the port state from the counter table (updated at

2 second intervals). If a counter is exceeded on a port, the CPU is shutdown. All packets, except BPDU packets, on the port are dropped. If the port remains in shutdown status for a configurable period (the count down value), the port enters shutdown forever status. The port link is down and remains disabled until either the configurable recover timer is timed out or the CLI command “config ports [ <portlist> | all ] state enable" is manually entered.

The Traffic Control commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

Command config traffic control config traffic trap show traffic control config traffic control auto_recover_time config traffic control_recover

Parameters

[<portlist> | all] {broadcast [enable| disable] | multicast [enable | disable] | [dlf | unicast ] [enable | disable] | action [ drop | shutdown ] | threshold <value 0-

255000 > | countdown [<min 0> | <min 3-30> | disable] | time_interval <sec 5-

600>}

[ none | storm_occurred | storm_cleared | both ]

Each command is listed, in detail, in the following sections.

config traffic control

Purpose

Syntax

Description

Parameters

Used to configure broadcast/multicast packet storm control. Shutdown mode is provided to monitor the traffic rate in addition to the storm control drop mode. If traffic rate is too high, this port will be shut down. config traffic control [<portlist> | all] {broadcast [enable| disable] | multicast [enable | disable] | [dlf | unicast ] [enable | disable] | action [ drop | shutdown ] | threshold

<value 0-255000 > | countdown [<min 0> | <min 3-30> | disable] | time_interval <sec 5-

600>}

The config traffic control command configures broadcast/multicast/DLF storm control. portlist - Used to specify a range of ports to be configured. broadcast - Enable or disable broadcast storm control.

507

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

config traffic control

Restrictions multicast - Enable or disable multicast storm control. dlf - Enable or disable unknown packet storm control. ( Supported for drop mode only) action - One of the two options for action are specified for storm control, shutdown of drop mode. Shutdown mode is a function of software, drop mode is implemented by the chip. If shutdown mode is specified, it is necessary to configure values for the back_off and time_interval parameters. threshold - The upper threshold, at which point the specified storm control is triggered. The

<value>is the number of broadcast/multicast packets per second received by the switch that will trigger the storm traffic control measure. The threshold is expressed as PPS (packets per second) and must be an unsigned integer. time_interval - The sampling interval of received packet counts. The possible value will be 5-

600 seconds. The parameter is not applicable if “drop” (mode) is specified for the “action” parameter. countdown - Timer for shutdown mode. If a port enters the shutdown Rx state and this timer runs out, port will be shutdown forever. The parameter is not applicable if “drop” (mode) is specified for the “action” parameter. Default is 0 minutes. 0 disables the forever state, meaning that the port will not enter the shut down forever state. disable – Specifies that the countdown is disabled. The port will directly shutdown when the switch detects a storm.

Only Administrator and Operator-level users can issue this command.

Example usage:

To configure the parameters so that the traffic control status is enabled on ports 1-12:

DGS-3450:admin# config traffic control 1-12 broadcast enable action shutdown threshold 1 countdown 5 time_interval 10

Command: config traffic control 1-12 broadcast enable action shutdown threshold 1 countdown 5 time_interval 10

P ASSWORD R ECOVERY P ROCEDURE

This chapter describes the procedure for resetting passwords on D-Link Switches. Authenticating any user who tries to access networks is necessary and important. The basic authentication method used to accept qualified users is through a local login, utilizing a Username and Password. Sometimes, passwords get forgotten or destroyed, so network administrators need to reset these passwords. This chapter explains how the Password Recovery feature can help network administrators reach this goal.

The following steps explain how to use the Password Recovery feature on D-Link devices to easily recover passwords.

Complete these steps to reset the password:

1. For security reasons, the Password Recovery feature requires the user to physically access the device.

Therefore this feature is only applicable when there is a direct connection to the console port of the device. It is necessary for the user needs to attach a terminal or PC with terminal emulation to the console port of the switch.

2. Power on the Switch. After the runtime image is loaded to 100%, the Switch will allow 2 seconds for the user to press the hotkey [^] (Shift + 6) to enter the “Password Recovery Mode.” Once the Switch enters the “Password

Recovery Mode,” all ports on the Switch will be disabled.

Boot Procedure 1.00-B13

Password Recovery Mode

3. In the “Password Recovery Mode” only the following commands can be used.

Command reset config reboot reset account reset password

{<username>} show account

Parameter

The reset config command resets the whole configuration back to the default values.

The reboot command exits the Reset Password Recovery Mode and restarts the switch. A confirmation message will be displayed to allow the user to save the current settings.

The reset account command deletes all the previously created accounts.

The reset password command resets the password of the specified user. If a username is not specified, the passwords of all users will be reset.

The show account command displays all previously created accounts.
