About This Manual
This document describes command-line interface (CLI) commands you use to view and configure
XSM7224S software. You can access the CLI by using a direct connection to the serial port or by using telnet or SSH over a remote network connection.
Note: This document contains both standalone and stacking commands.
Audience
This document is for system administrators who configure and operate systems using XSM7224S software. It provides an understanding of the configuration options of the software.
Software engineers who integrate software into their hardware platform can also benefit from a description of the configuration options.
This document assumes that the reader has an understanding of the software base and has read the appropriate specification for the relevant networking device platform. It also assumes that the reader has a basic knowledge of Ethernet and networking concepts.
Refer to the release notes for the application-level code. The release notes detail the platformspecific functionality of the Switching, Routing, SNMP, Configuration, Management, and other packages. The suite of features the packages support is not available on all the platforms to which software has been ported.
About the Software
The software has two purposes:
• Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information contained in the frames.
• Provide a complete device management portfolio to the network administrator. ix v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
Scope
The software encompasses both hardware and software support. The software is partitioned to run in the following processors:
• CPU – This code runs the networking device management portfolio and controls the overall networking device hardware. It also assists in frame forwarding, as needed and specified. This code is designed to run on multiple platforms with minimal changes from platform to platform.
• Networking device processor – This code does the majority of the packet switching, usually at wire speed. This code is platform dependent, and substantial changes might exist across products.
Product Concept
Fast Ethernet and Gigabit Ethernet switching continues to evolve from high-end backbone applications to desktop switching applications. The price of the technology continues to decline, while performance and feature sets continue to improve. Devices that are capable of switching
Layers 2, 3, and 4 are increasingly in demand. The software provides a flexible solution to these ever-increasing needs.
The exact functionality provided by each networking device on which the software base runs varies depending upon the platform and requirements of the FASTPATH software.
The software includes a set of comprehensive management functions for managing both the software and the network. You can manage the software by using one of the following three methods:
• Command-Line Interface (CLI)
• Simple Network Management Protocol (SNMP)
• Web-based
Each of the management methods enables you to configure, manage, and control the software locally or remotely using in-band or out-of-band mechanisms. Management is standards-based, with configuration parameters and a private MIB providing control for functions not completely specified in the MIBs.

November 2010 Product update: New firmware and new user Interface xii v1.0, November 2010
Chapter 1
Using the Command-Line Interface
The command-line interface (CLI) is a text-based way to manage and monitor the system. You can access the CLI by using a direct serial connection or by using a remote logical connection with telnet or SSH.
This chapter describes the CLI syntax, conventions, and modes. It contains the following sections:
•
•
“Command Conventions” on page 1-2
•
“Common Parameter Values” on page 1-3
•
“Unit/Slot/Port Naming Convention” on page 1-3
•
“Using the “No” Form of a Command” on page 1-4
•
“Managed Switch Modules” on page 1-5
•
•
“Command Completion and Abbreviation” on page 1-9
•
“CLI Error Messages” on page 1-9
•
“CLI Line-Editing Conventions” on page 1-10

Command Syntax
A command is one or more words that might be followed by one or more parameters. Parameters can be required or optional values.
Some commands, such as show network or clear vlan, do not require parameters. Other commands, such as network parms, require that you supply a value after the command. You must type the parameter values in a specific order, and optional parameters follow required parameters. The following example describes the network parms command syntax:
Format network parms <ipaddr> <netmask> [gateway]
1-1 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
• network parms is the command name.
• <ipaddr> and <netmask> are parameters and represent required values that you must enter after you type the command keywords.
• [gateway] is an optional parameter, so you are not required to enter a value in place of the parameter.
The CLI Command Reference lists each command by the command name and provides a brief description of the command. Each command reference also contains the following information:
• Format shows the command keywords and the required and optional parameters.
• Mode identifies the command mode you must be in to access the command.
• Default shows the default value, if any, of a configurable setting on the device.
The show commands also contain a description of the information that the command shows.
Command Conventions
In this document, the command name is in bold font. Parameters are in italic font. You must replace the parameter name with an appropriate value, which might be a name or number.
Parameters are order dependent.
The parameters for a command might include mandatory values, optional values, or keyword
choices. Table 1 describes the conventions this document uses to distinguish between value types.
Table 1. Parameter Conventions

Common Parameter Values
Parameter values might be names (strings) or numbers.To use spaces as part of a name parameter, enclose the name value in double quotes. For example, the expression “System Name with
Spaces” forces the system to accept the spaces. Empty strings (““) are not valid user-defined strings.
describes common parameter values and value formatting.
Table 2. Parameter Descriptions
Parameter Description ipaddr This parameter is a valid IP address. You can enter the IP address in the following formats: a (32 bits) a.b (8.24 bits) a.b.c (8.8.16 bits) a.b.c.d (8.8.8.8) ipv6-address
In addition to these formats, the CLI accepts decimal, hexadecimal and octal formats through the following input formats (where n is any valid hexadecimal, octal or decimal number):
0xn (CLI assumes hexadecimal format)
0n (CLI assumes octal format with leading zeros) n (CLI assumes decimal format)
FE80:0000:0000:0000:020F:24FF:FEBF:DBCB, or
FE80:0:0:0:20F:24FF:FEBF:DBCB, or
FE80::20F24FF:FEBF:DBCB, or
FE80:0:0:0:20F:24FF:128:141:49:32
For additional information, refer to RFC 3513.
Interface or unit/slot/port
Valid slot and port number separated by forward slashes. For example, 0/1 represents slot number 0 and port number 1.
Logical Interface Represents a logical slot and port number. This is applicable in the case of a portchannel (LAG). You can use the logical unit/slot/port to configure the port-channel.
Character strings Use double quotation marks to identify character strings, for example, “System Name with Spaces”. An empty string (“”) is not valid.
Unit/Slot/Port Naming Convention
Managed switch software references physical entities such as cards and ports by using a unit/slot/ port naming convention. The software also uses this convention to identify certain logical entities, such as Port-Channel interfaces.
Using the Command-Line Interface 1-3 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case of logical and CPU ports it also identifies the type of interface or port.
Table 3. Type of Slots
Slot Type Description
Physical slot numbers Physical slot numbers begin with zero, and are allocated up to the maximum number of physical slots.
Logical slot numbers
CPU slot numbers
Logical slots immediately follow physical slots and identify port-channel (LAG) or router interfaces.
The CPU slots immediately follow the logical slots.
The port identifies the specific physical port or logical interface being managed on a given slot.
Table 4. Type of Ports
Port Type
Physical Ports
Logical Interfaces
CPU ports
Description
The physical ports for each slot are numbered sequentially starting from zero.
Port-channel or Link Aggregation Group (LAG) interfaces are logical interfaces that are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
Loopback interfaces are logical interfaces that are always up.
Tunnel interfaces are logical point-to-point links that carry encapsulated packets.
CPU ports are handled by the driver as one or more physical entities located on physical slots.
Note: In the CLI, loopback and tunnel interfaces do not use the unit/slot/port format. To specify a loopback interface, you use the loopback ID. To specify a tunnel interface, you use the tunnel ID.
Using the “No” Form of a Command
The no keyword is a specific form of an existing command and does not represent a new or distinct command. Almost every configuration command has a no form. In general, use the no form to reverse the action of a command or reset a value back to the default. For example, the no
Using the Command-Line Interface v1.0, November 2010
1-4
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
shutdown configuration command reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form.
Managed Switch Modules
Managed switch software consists of flexible modules that can be applied in various combinations to develop advanced Layer 2/3/4+ products. The commands and command modes available on your switch depend on the installed modules. Additionally, for some show commands, the output fields might change based on the modules included in the software.
The software suite includes the following modules:
• Switching (Layer 2)
• Quality of Service
• Management (CLI, Web UI, and SNMP)
• IPv6 Management—Allows management of the device through an IPv6 through an IPv6 address without requiring the IPv6 Routing package in the system. The management address can be associated with the network port (front-panel switch ports), a routine interface (port or
VLAN) and the Service port.
• Stacking
Not all modules are available for all platforms or software releases.
Command Modes
The CLI groups commands into modes according to the command function. Each of the command modes supports specific software commands. The commands in one mode are not available until you switch to that particular mode, with the exception of the User EXEC mode commands. You can execute the User EXEC mode commands in the Privileged EXEC mode.
The command prompt changes in each command mode to help you identify the current mode.
Table 5 describes the command modes and the prompts visible in that mode.
Note: The command modes available on your switch depend on the software modules that are installed. For example, a switch that does not support BGPv4 does not have the Router BGPv4 Command Mode.

Global Config switch renumber
This command changes the switch identifier for a switch in the stack. The <oldunit> is the current switch identifier on the switch whose identifier is to be changed. The <newunit> is the updated value of the switch identifier. Upon execution, the switch will be configured with the configuration information for the new switch, if any. The old switch configuration information will be retained, however the old switch will be operationally unplugged. This command is executed on the Primary Management Unit.
Note: If the management unit is renumbered, then the running configuration is no longer applied (i.e. the stack acts as if the configuration had been cleared)

Global Config movemanagement
This command moves the Primary Management Unit functionality from one switch to another.
The <fromunit> is the switch identifier on the current Primary Management Unit. The
<tounit> is the switch identifier on the new Primary Management Unit. Upon execution, the entire stack (including all interfaces in the stack) is unconfigured and reconfigured with the configuration on the new Primary Management Unit. After the reload is complete, all stack management capability must be performed on the new Primary Management Unit. To preserve the current configuration across a stack move, execute the copy system:running-config

Stack Firmware Synchronization Commands
Stack firmware synchronization provides an automatic mechanism to synchronize the firmware on stack members whose firmware version differs from the version running on the stack manager.
This operation can result in either an upgrade or downgrade of firmware on the mismatched stack member. However, this operation does not attempt to synchronize the stack to the latest firmware in the stack.
During firmware transfer and upgrade, operations such as code download and move management can result in undesirable behavior, such as firmware corruption on a code mismatched stack member. As a result, you receive an error if you try to access the following operations from the user interface during stack firmware synchronization:
• Move management
• Unit renumbering
• Code download
Stacking Commands 2-14 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
• Delete image
• Update bootcode
• Clear config
A reboot operation is allowed during stack firmware synchronization.
If the firmware is corrupted during stack firmware synchronization, manual intervention by the administrator is required to restore the switch to working condition.
During stack firmware synchronization, traps are generated on start, completion, or failure.
Note:
• Non-deterministic upgrade behavior
On bootup, the image that gets synchronized depends on the one that becomes the manager.
Which code version the new stack synchronizes to is fully deterministic, but might not be obvious to the user as it depends entirely on which unit becomes the manager. This might be decided by a MAC address comparison. If the administrator wants a particular version to be used by the stack, he should first ensure that this particular unit becomes stack manager.
• Bootcode Upgrades
Bootcode upgrades are not initiated by the stack firmware synchronization. boot auto-copy-sw
This command enables or disables stack firmware synchronization.

Voice VLAN Commands
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch ports to carry voice traffic with defined priority so as to enable separation of voice and data traffic coming onto the port. The benefits of using Voice VLAN is to ensure that the sound quality of an
IP phone could be safeguarded from deteriorating when the data traffic on the port is high.
Also the inherent isolation provided by VLANs ensures that inter-VLAN traffic is under management control and that network- attached clients cannot initiate a direct attack on voice components. QoS-based on IEEE 802.1P class of service (CoS) uses classification and scheduling to sent network traffic from the switch in a predictable manner. The system uses the source MAC of the traffic traveling through the port to identify the IP phone data flow.

Protected Ports Commands
This section describes commands you use to configure and view protected ports on a switch.
Protected ports do not forward traffic to each other, even if they are on the same VLAN. However, protected ports can forward traffic to all unprotected ports in their group. Unprotected ports can forward traffic to both protected and unprotected ports. Ports are unprotected by default.
If an interface is configured as a protected port, and you add that interface to a Port Channel or
Link Aggregation Group (LAG), the protected port status becomes operationally disabled on the interface, and the interface follows the configuration of the LAG port. However, the protected port configuration for the interface remains unchanged. Once the interface is no longer a member of a
LAG, the current configuration for that interface automatically becomes effective.

GARP Commands
This section describes the commands you use to configure Generic Attribute Registration Protocol
(GARP) and view GARP status. The commands in this section affect both GARP VLAN
Registration Protocol (GVRP) and Garp Multicast Registration Protocol (GMRP). GARP is a protocol that allows client stations to register with the switch for membership in VLANS (by using
GVMP) or multicast groups (by using GVMP).
set garp timer join
This command sets the GVRP join time for one port (Interface Config mode) or all (Global Config mode) and per GARP. Join time is the interval between the transmission of GARP Protocol Data
Units (PDUs) registering (or re-registering) membership for a VLAN or multicast group. This command has an effect only when GVRP is enabled. The time is from 10 to 100 (centiseconds).
The value 20 centiseconds is 0.2 seconds.

Storm-Control Commands
This section describes commands you use to configure storm-control and view storm-control configuration information. A traffic storm is a condition that occurs when incoming packets flood the LAN, which creates performance degradation in the network. The Storm-Control feature protects against this condition.
The 7000 series provides broadcast, multicast, and unicast story recovery for individual interfaces.
Unicast Storm-Control protects against traffic whose MAC addresses are not known by the system. For broadcast, multicast, and unicast storm-control, if the rate of traffic ingressing on an interface increases beyond the configured threshold for that type, the traffic is dropped.
To configure storm-control, you will enable the feature for all interfaces or for individual interfaces, and you will set the threshold (storm-control level) beyond which the broadcast, multicast, or unicast traffic will be dropped. The Storm-Control feature allows you to limit the rate of specific types of packets through the switch on a per-port, per-type, basis.
Configuring a storm-control level also enables that form of storm-control. Disabling a stormcontrol level (using the “no” version of the command) sets the storm-control level back to the default value and disables that form of storm-control. Using the “no” version of the “stormcontrol” command (not stating a “level”) disables that form of storm-control but maintains the configured “level” (to be active the next time that form of storm-control is enabled.)
Note: The actual rate of ingress traffic required to activate storm-control is based on the size of incoming packets and the hard-coded average packet size of 512 bytes - used to calculate a packet-per-second (pps) rate - as the forwarding-plane requires pps versus an absolute rate kbps. For example, if the configured limit is 10%, this is converted to ~25000 pps, and this pps limit is set in forwarding plane
(hardware). You get the approximate desired output when 512bytes packets are used.
storm-control broadcast
Use this command to enable broadcast storm recovery mode for a specific interface. If the mode is enabled, broadcast storm recovery is active and, if the rate of L2 broadcast traffic ingressing on an interface increases beyond the configured threshold, the traffic will be dropped. Therefore, the rate of broadcast traffic will be limited to the configured threshold.

Port-Channel/LAG (802.3ad) Commands
This section describes the commands you use to configure port-channels, which are also known as link aggregation groups (LAGs). Link aggregation allows you to combine multiple full-duplex
Ethernet links into a single logical link. Network devices treat the aggregation as if it were a single link, which increases fault tolerance and provides load sharing. The LAG feature initially load
Switching Commands 3-94 v1.0, November 2010

shares traffic based upon the source and destination MAC address.Assign the port-channel (LAG)
VLAN membership after you create a port-channel. If you do not assign VLAN membership, the port-channel might become a member of the management VLAN which can result in learning and switching issues.
A port-channel (LAG) interface can be either static or dynamic, but not both. All members of a port channel must participate in the same protocols.) A static port-channel interface does not require a partner system to be able to aggregate its member ports.
Note: If you configure the maximum number of dynamic port-channels (LAGs) that your platform supports, additional port-channels that you configure are automatically static.
addport
This command adds one port to the port-channel (LAG). The interface is a logical unit/slot/port number or a group ID of a configured port-channel.

Global Config port-channel load-balance
This command selects the load-balancing option used on a port-channel (LAG). Traffic is balanced on a port-channel (LAG) by selecting one of the links in the channel over which to transmit specific packets. The link is selected by creating a binary pattern from selected fields in a packet, and associating that pattern with a particular link.
Load-balancing is not supported on every device. The range of options for load-balancing may vary per device. The XSM7224S also supports enhanced hashing mode, which has the following advantages:
• MODULO-N (where N is the number of active link members in a LAG) operation based on the number of ports in the LAG
• Packet attributes selection based on the packet type: For L2 packets, source and destination
MAC address are used for hash computation. For L3 packets, source IP, destination IP address,
TCP/UDP ports are used.
• Non-Unicast traffic and unicast traffic is hashed using a common hash algorithm
• Excellent load balancing performance

monitor session
This command configures a probe port and a monitored port for monitor session (port monitoring).
Use the source interface <unit/slot/port> parameter to specify the interface to monitor. Use rx to monitor only ingress packets, or use tx to monitor only egress packets. If you do not specify an {rx | tx} option, the destination port monitors both ingress and egress packets. Use the destination interface <unit/slot/port> to specify the interface to receive the monitored traffic. Use the mode parameter to enabled the administrative mode of the session. If enabled, the probe port monitors all the traffic received and transmitted on the physical monitored port.
Format
Mode monitor session <session-id> {source interface <unit/slot/port> [{rx
| tx}] | destination interface <unit/slot/port> | mode}
Global Config no monitor session
.
Use this command without optional parameters to remove the monitor session (port monitoring) designation from the source probe port, the destination monitored port and all VLANs. Once the port is removed from the VLAN, you must manually add the port to any desired VLANs. Use the source interface <unit/slot/port> parameter or destination interface
<unit/slot/port> to remove the specified interface from the port monitoring session. Use the mode parameter to disable the administrative mode of the session
Note: Since the current version of 7000 series software only supports one session, if you do not supply optional parameters, the behavior of this command is similar to the behavior of the no monitor command.

Static MAC Filtering
The commands in this section describe how to configure static MAC filtering. Static MAC filtering allows you to configure destination ports for a static multicast MAC filter irrespective of the platform. macfilter
This command adds a static MAC filter entry for the MAC address <macaddr> on the VLAN
<vlanid> . The value of the <macaddr> parameter is a 6-byte hexadecimal number in the format of b1:b2:b3:b4:b5:b6. The restricted MAC Addresses are: 00:00:00:00:00:00,
01:80:C2:00:00:00 to 01:80:C2:00:00:0F, 01:80:C2:00:00:20 to 01:80:C2:00:00:21, and
FF:FF:FF:FF:FF:FF. The <vlanid> parameter must identify a valid VLAN.
The number of static mac filters supported on the system is different for MAC filters where source ports are configured and MAC filters where destination ports are configured.
• For unicast MAC address filters and multicast MAC address filters with source port lists, the maximum number of static MAC filters supported is 20.
• For multicast MAC address filters with destination ports configured, the maximum number of static filters supported is 256.
i.e. For current platforms, you can configure the following combinations:
• Unicast MAC and source port (max = 20)
• Multicast MAC and source port (max=20)
• Multicast MAC and destination port (only) (max=256)
• Multicast MAC and source ports and destination ports (max=20)

Dynamic ARP Inspection Commands
Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP packets. DAI prevents a class of man-in-the-middle attacks, where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors. The miscreant sends ARP requests or responses mapping another station’s IP address to its own MAC address.
DAI relies on DHCP snooping. DHCP snooping listens to DHCP message exchanges and builds a binding database of valid {MAC address, IP address, VLAN, and interface} tuples.
When DAI is enabled, the switch drops ARP packets whose sender MAC address and sender IP address do not match an entry in the DHCP snooping bindings database. You can optionally configure additional ARP packet validation.
ip arp inspection vlan
Use this command to enable Dynamic ARP Inspection on a list of comma-separated VLAN ranges.

IGMP Snooping Configuration Commands
This section describes the commands you use to configure IGMP snooping. The software supports
IGMP Versions 1, 2, and 3. The IGMP snooping feature can help conserve bandwidth because it allows the switch to forward IP multicast traffic only to connected hosts that request multicast traffic. IGMPv3 adds source filtering capabilities to IGMP versions 1 and 2.
set igmp
This command enables IGMP Snooping on the system (Global Config Mode) or an interface
(Interface Config Mode). This command also enables IGMP snooping on a particular VLAN
(VLAN Config Mode) and can enable IGMP snooping on all interfaces participating in a VLAN.
If an interface has IGMP Snooping enabled and you enable this interface for routing or enlist it as a member of a port-channel (LAG), IGMP Snooping functionality is disabled on that interface.
IGMP Snooping functionality is re-enabled if you disable routing or remove port-channel (LAG) membership from an interface that has IGMP Snooping enabled.
The IGMP application supports the following activities:
• Validation of the IP header checksum (as well as the IGMP header checksum) and discarding of the frame upon checksum error.
• Maintenance of the forwarding table entries based on the MAC address versus the IP address.

Global Config set igmp fast-leave
This command enables or disables IGMP Snooping fast-leave admin mode on a selected interface or VLAN. Enabling fast-leave allows the switch to immediately remove the layer 2 LAN interface from its forwarding table entry upon receiving an IGMP leave message for that multicast group without first sending out MAC-based general queries to the interface.
You should enable fast-leave admin mode only on VLANs where only one host is connected to each layer 2 LAN port. This prevents the inadvertent dropping of the other hosts that were connected to the same layer 2 LAN port but were still interested in receiving multicast traffic directed to that group. Also, fast-leave processing is supported only with IGMP version 2 hosts.

IGMP Snooping Querier Commands
IGMP Snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the “IGMP Querier”. The
IGMP query responses, known as IGMP reports, keep the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive updated membership information in a timely fashion, it will stop forwarding multicasts to the port where the end device is located.
This section describes commands used to configure and display information on IGMP Snooping
Queriers on the network and, separately, on VLANs. set igmp querier
Use this command to enable IGMP Snooping Querier on the system, using Global Config mode, or on a VLAN. Using this command, you can specify the IP Address that the Snooping Querier switch should use as the source address while generating periodic queries.
Switching Commands 3-151 v1.0, November 2010

If a VLAN has IGMP Snooping Querier enabled and IGMP Snooping is operationally disabled on it, IGMP Snooping Querier functionality is disabled on that VLAN. IGMP Snooping functionality is re-enabled if IGMP Snooping is operational on the VLAN.
Note: The Querier IP Address assigned for a VLAN takes preference over global configuration.
The IGMP Snooping Querier application supports sending periodic general queries on the VLAN to solicit membership reports.

Denial of Service Commands
This section describes the commands you use to configure Denial of Service (DoS) Control. The software provides support for classifying and blocking specific types of Denial of Service attacks.
You can configure your system to monitor and block these types of attacks:
• SIP=DIP: Source IP address = Destination IP address.
• First Fragment:TCP Header size smaller then configured value.
• TCP Fragment: IP Fragment Offset = 1.
• TCP Flag: TCP Flag SYN set and Source Port < 1024 or TCP Control Flags = 0 and TCP
Sequence Number = 0 or TCP Flags FIN, URG, and PSH set and TCP Sequence Number = 0 or TCP Flags SYN and FIN set.
• L4 Port: Source TCP/UDP Port = Destination TCP/UDP Port.
• ICMP: Limiting the size of ICMP Ping packets.

Priority-Based Flow control commands
Ordinarily, when flow control is enabled on a physical link, it applies to all traffic on the link.
When congestion occurs, the hardware sends pause frames that temporarily suspend traffic flow.
Pausing traffic helps prevent buffer overflow and dropped frames.
Priority-based flow control provides a way to distinguish which traffic on physical link is paused when congestion occurs, based on the priority of the traffic. An interface can be configured to pause only high priority (i.e., loss-sensitive) traffic when necessary to prevent dropped frames, while allowing traffic that has greater loss tolerance to continue to flow on the interface.
Priorities are differentiated by the priority field of the IEEE 802.1Q VLAN header, which identifies an IEEE 802.1p priority value. In FASTPATH, these priority values must be mapped to internal class-of-service (CoS) values.
Switching Commands 3-203 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
To enable priority-based flow control for a particular CoS value on an interface:
• Ensure that VLAN tagging is enabled on the interface so that the 802.1p priority values are carried through the network.
• Ensure that 802.1p priority values are mapped to FASTPATH CoS values.
• Use the datacenter-bridging priority-flow-control mode on command to enable priority-based flow control on the the interface.
• Use the datacenter-bridging priority-flow-control priority command to specify the CoS values that should be paused ("no-drop") due to greater loss sensitivity. Unless configured as "nodrop", all CoS priorities are considered nonpausable ("drop") when priority-based flow control is enabled.
When priority-flow-control is disabled, the interface defaults to the IEEE 802.3x flow control setting for the interface. When priority-based flow control is enabled, the interface will not pause any CoS unless there is at least one no-drop priority.

• Show commands display switch settings, statistics, and other information.
• Configuration commands configure features and options of the switch. For every configuration command, there is a show command that displays the configuration setting.
• Clear commands clear some or all of the settings to factory defaults.
Address Resolution Protocol (ARP) Commands
This section describes the commands you use to configure ARP and to view ARP information on the switch. ARP associates IP addresses with MAC addresses and stores the information as ARP entries in the ARP cache.
arp
This command creates an ARP entry. The value for <ipaddress> is the IP address of a device on a subnet attached to an existing routing interface. <macaddr> is a unicast MAC address for that device.
4-1 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
The format of the MAC address is 6 two-digit hexadecimal numbers that are separated by colons, for example 00:06:29:32:81:40.
Format
Mode
arp <ipaddress> <macaddr>
Global Config no arp
This command deletes an ARP entry. The value for <arpentry> is the IP address of the interface. The value for <ipaddress> is the IP address of a device on a subnet attached to an existing routing interface. <macaddr> is a unicast MAC address for that device.
Format
Mode
no arp <ipaddress> <macaddr>
Global Config ip proxy-arp
This command enables proxy ARP on a router interface. Without proxy ARP, a device only responds to an ARP request if the target IP address is an address configured on the interface where the ARP request arrived. With proxy ARP, the device may also respond if the target IP address is reachable. The device only responds if all next hops in its route to the destination are through interfaces other than the interface that received the ARP request.

Global Config ip address
This command configures an IP address on an interface. You can also use this command to configure one or more secondary IP addresses on the interface.The value for <ipaddr> is the IP address of the interface. The value for <subnetmask> is a 4-digit dotted-decimal number which represents the subnet mask of the interface. The subnet mask must have contiguous ones and be no longer than 30 bits, for example 255.255.255.0. This command adds the label IP address in show ip interface .
Format

This command configures a static route. The <ipaddr> parameter is a valid IP address, and
<subnetmask> is a valid subnet mask. The <nexthopip> parameter is a valid IP address of the next hop router. Specifying Null0 as nexthop parameter adds a static reject route. The optional <preference> parameter is an integer (value from 1 to 255) that allows you to specify the preference value (sometimes called “administrative distance”) of an individual static route.
Among routes to the same destination, the route with the lowest preference value is the route

entered into the forwarding database. By specifying the preference of a static route, you control whether a static route is more or less preferred than routes from dynamic routing protocols. The preference also controls whether a static route is more or less preferred than other static routes to the same destination. A route with a preference of 255 cannot be used to forward traffic.
For the static routes to be visible, you must perform the following steps:
• Enable ip routing globally.
• Enable ip routing for the interface.
• Confirm that the associated link is also up.

Global Config ip route distance
This command sets the default distance (preference) for static routes. Lower route distance values are preferred when determining the best route. The ip route and ip route default commands allow you to optionally set the distance (preference) of an individual static route. The default distance is used when no distance is specified in these commands. Changing the default distance does not update the distance of existing static routes, even if they were assigned the original default distance. The new default distance will only be applied to static routes created after invoking the ip route distance command.

Interface Config ip mtu
This command sets the IP Maximum Transmission Unit (MTU) on a routing interface. The IP
MTU is the size of the largest IP packet that can be transmitted on the interface without fragmentation. The software currently does not fragment IP packets.
• Packets forwarded in hardware ignore the IP MTU.
• Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing interface.
Packets originated on the router, such as OSPF packets, may be fragmented by the IP stack. The IP stack uses its default IP MTU and ignores the value set using the ip mtu command.
OSPF advertises the IP MTU in the Database Description packets it sends to its neighbors during database exchange. If two OSPF neighbors advertise different IP MTUs, they will not form an adjacency. (unless OSPF has been instructed to ignore differences in IP MTU with the ip ospf mtu-ignore command.)
Note: The IP MTU size refers to the maximum size of the IP packet (IP Header + IP payload). It does not include any extra bytes that may be required for Layer-2 headers. To receive and process packets, the Ethernet MTU (see
) must take into account the size of the Ethernet header.

Routing Commands 4-17 v1.0, November 2010
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
To administratively control the traffic destined to a particular network and prevent it from being forwarded through the router, you can configure a static reject route on the router. Such traffic would be discarded and the ICMP destination unreachable message is sent back to the source. This is typically used for preventing routing loops. The reject route added in the RTO is of the type
OSPF Inter-Area. Reject routes (routes of REJECT type installed by any protocol) are not redistributed by OSPF/RIP. Reject routes are supported in both OSPFv2 and OSPFv3.
The following shows example CLI display output for the command.

IP Helper Commands
This section describes the commands to configure a DHCP relay agent with multiple DHCP server addresses per routing interface, and to use different server addresses for client packets arriving on different interfaces on the relay agent.
ip helper-address (Global Config)
Use the Global Configuration ip helper-address command to have the switch forward User
Datagram Protocol (UDP) broadcasts received on an interface. To disable the forwarding of broadcast packets to specific addresses, use the no form of this command.
The ip helper-address command forwards specific UDP broadcast from one interface to another.
You can define many helper addresses but the total number of address-port pairs is limited to 128 for the whole device. The setting of a helper address for a specific interface has precedence over a setting of a helper address for all interfaces. You cannot enable forwarding of BOOTP/DHCP packets (ports 67,68) with this command. If you want to relay BOOTP/DHCP packets, use the
DHCP relay commands.
Ip-address: Destination broadcast or host address to be used when forwarding UDP broadcasts.
You can specify 0.0.0.0 to indicate not to forward the UDP packet to any host and use
"255.255.255.255" to broadcast the UDP packets to all hosts on the target subnet.
udp-port-list: The broadcast packet destination UDP port number to forward. If not specified, packets for the default services are forwarded to the helper address. Valid range, 0-65535.

cos-queue random-detect
This command activates weighted random early discard (WRED) for each specified queue on the interface. Specific WRED parameters are configured using the randomdetect queue-parms and the random-detect exponential-weighting-constant commands. When specified in Interface Config' mode, this command affects a single interface only, whereas in Global Config mode, it applies to all interfaces. At least one, but no more than n, queue-id values are specified with this command.
Duplicate queue-id values are ignored. Each queue-id value ranges from 0 to (n-1), where n is the total number of queues supported per interface. The number n is platform dependant and corresponds to the number of supported queues (traffic classes).

Interface Config random-detect queue-parms
This command is used to configure WRED parameters for each drop precedence level supported by a queue. It is used only when per-COS queue configuration is enabled (using the cos-queue
random-detect command).
min-thresh is the minimum threshold the queue depth (as a percentage) where WRED starts marking and dropping traffic.
max-thresh is the maximum threshold is the queue depth (as a percentage) above which WRED marks / drops all traffic.
drop-probability is the percentage probability that WRED will mark/drop a packet, when the queue depth is at the maximum threshold. (The drop probability increases linearly from 0 just before the minimum threshold, to this value at the maximum threshold, then goes to 100% for larger queue depths). Each parameter is specified for each possible drop precedence ("color" of
TCP traffic).

Differentiated Services (DiffServ) Commands
This section describes the commands you use to configure QOS Differentiated Services
(DiffServ).
You configure DiffServ in several stages by specifying three DiffServ components:
1. Class
Quality of Service (QoS) Commands v1.0, November 2010
5-9
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
a. Creating and deleting classes.
b. Defining match criteria for a class.
2. Policy
a. Creating and deleting policies
b. Associating classes with a policy c.
Defining policy statements for a policy/class combination
3. Service
a. Adding and removing a policy to/from an inbound interface
The DiffServ class defines the packet filtering criteria. The attributes of a DiffServ policy define the way the switch processes packets. You can define policy attributes on a per-class instance basis. The switch applies these attributes when a match occurs.
Packet processing begins when the switch tests the match criteria for a packet. The switch applies a policy to a packet when it finds a class match within that policy.
The following rules apply when you create a DiffServ class:
• Each class can contain a maximum of one referenced (nested) class
• Class definitions do not support hierarchical service policies
A given class definition can contain a maximum of one reference to another class. You can combine the reference with other match criteria. The referenced class is truly a reference and not a copy since additions to a referenced class affect all classes that reference it. Changes to any class definition currently referenced by any other class must result in valid class definitions for all derived classes, otherwise the switch rejects the change. You can remove a class reference from a class definition.
The only way to remove an individual match criterion from an existing class definition is to delete the class and re-create it.
Note: The mark possibilities for policing include CoS, IP DSCP, and IP Precedence.
While the latter two are only meaningful for IP packet types, CoS marking is allowed for both IP and non-IP packets, since it updates the 802.1p user priority field contained in the VLAN tag of the layer 2 packet header.

DiffServ Class Commands
Use the DiffServ class commands to define traffic classification. To classify traffic, you specify
Behavior Aggregate (BA), based on DSCP and Multi-Field (MF) classes of traffic (name, match criteria)
This set of commands consists of class creation/deletion and matching, with the class match commands specifying Layer 3, Layer 2, and general match criteria. The class match criteria are also known as class rules, with a class definition consisting of one or more rules to identify the traffic that belongs to the class.
Note: Once you create a class match criterion for a class, you cannot change or delete the criterion. To change or delete a class match criterion, you must delete and re-create the entire class.
The CLI command root is class-map.

5-11
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
class-map
This command defines a DiffServ class of type match-all. When used without any match condition, this command enters the class-map mode. The <class-map-name> is a case sensitive alphanumeric string from 1 to 31 characters uniquely identifying an existing DiffServ class.
Note: The class-map-name 'default' is reserved and must not be used.
The class type of match-all indicates all of the individual match conditions must be true for a packet to be considered a member of the class.This command may be used without specifying a class type to enter the Class-Map Config mode for an existing DiffServ class.
Note: The optional keywords [{ipv4 | ipv6}] specify the Layer 3 protocol for this class. If not specified, this parameter defaults to ‘ipv4’. This maintains backward compatibility for configurations defined on systems before IPv6 match items were supported.
Note: The CLI mode is changed to Class-Map Config or Ipv6-Class-Map Config when this command is successfully executed depending on the [{ipv4 | ipv6}] keyword specified.
Format
Mode
class-map match-all <class-map-name> [{ipv4 | ipv6}]
Global Config no class-map
This command eliminates an existing DiffServ class. The <class-map-name> is the name of an existing DiffServ class. (The class name ‘default’ is reserved and is not allowed here.) This command may be issued at any time; if the class is currently referenced by one or more policies or by any other class, the delete action fails.

match ip tos
This command adds to the specified class definition a match condition based on the value of the IP
TOS field in a packet, which is defined as all eight bits of the Service Type octet in the IP header.
The value of <tosbits> is a two-digit hexadecimal number from 00 to ff. The value of
<tosmask> is a two-digit hexadecimal number from 00 to ff. The <tosmask> denotes the bit positions in <tosbits> that are used for comparison against the IP TOS field in a packet. For example, to check for an IP TOS value having bits 7 and 5 set and bit 1 clear, where bit 7 is most significant, use a <tosbits> value of a0 (hex) and a <tosmask> of a2 (hex).
Note: The IP DSCP, IP Precedence, and IP ToS match conditions are alternative ways to specify a match criterion for the same Service Type field in the IP header, but with a slightly different user notation.
Note: This “free form” version of the IP DSCP/Precedence/TOS match specification gives the user complete control when specifying which bits of the IP Service Type field are checked.

DiffServ Policy Commands
Use the DiffServ policy commands to specify traffic conditioning actions, such as policing and marking, to apply to traffic classes
Use the policy commands to associate a traffic class that you define by using the class command set with one or more QoS policy attributes. Assign the class/policy association to an interface to form a service. Specify the policy name when you create the policy.
Each traffic class defines a particular treatment for packets that match the class definition. You can associate multiple traffic classes with a single policy. When a packet satisfies the conditions of more than one class, preference is based on the order in which you add the classes to the policy.
The first class you add has the highest precedence.
This set of commands consists of policy creation/deletion, class addition/removal, and individual policy attributes.
Note: The only way to remove an individual policy attribute from a class instance within a policy is to remove the class instance and re-add it to the policy. The values associated with an existing policy attribute can be changed without removing the class instance.
The CLI command root is policy-map.

Note: This command fails if any attributes within the policy definition exceed the capabilities of the interface. Once a policy is successfully attached to an interface, any attempt to change the policy definition, that would result in a violation of the interface capabilities, causes the policy change attempt to fail.

MAC Access Control List (ACL) Commands
This section describes the commands you use to configure MAC ACL settings. MAC ACLs ensure that only authorized users have access to specific resources and block any unwarranted attempts to reach network resources.
The following rules apply to MAC ACLs:
• The maximum number of ACLs you can create is hardware dependent. The limit applies to all
ACLs, regardless of type.
• The system supports only Ethernet II frame types.
• The maximum number of rules per MAC ACL is hardware dependent.
mac access-list extended
This command creates a MAC Access Control List (ACL) identified by <name>, consisting of classification fields defined for the Layer 2 header of an Ethernet frame. The <name> parameter is a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying the MAC access list.
Quality of Service (QoS) Commands v1.0, November 2010

{deny | permit} (MAC ACL)
This command creates a new rule for the current MAC access list. Each rule is appended to the list of configured rules for the list.
Note: The 'no' form of this command is not supported, since the rules within a MAC ACL cannot be deleted individually. Rather, the entire MAC ACL must be deleted and re-specified.

5-34
ProSafe XSM7224S Managed Stackable Switch CLI Manual, Software Version 9.0
Note: An implicit 'deny all' MAC rule always terminates the access list.
A rule may either deny or permit traffic according to the specified classification fields. At a minimum, the source and destination MAC value must be specified, each of which may be substituted using the keyword any to indicate a match on any value in that field. The remaining command parameters are all optional, but the most frequently used parameters appear in the same relative order as shown in the command format.
The Ethertype may be specified as either a keyword or a four-digit hexadecimal value from
0x0600-0xFFFF. The currently supported <ethertypekey> values are: appletalk, arp, ibmsna, ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell, pppoe, rarp. Each of these translates into its equivalent Ethertype value(s).

The assign-queue parameter allows specification of a particular hardware queue for handling traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where n is the number of user configurable queues available for the hardware platform. The assign-queue parameter is valid only for a permit rule.
Note: The special command form {deny | permit} any any is used to match all Ethernet layer 2 packets, and is the equivalent of the IP access list “match every” rule.

Mac-Access-List Config mac access-group
This command either attaches a specific MAC Access Control List (ACL) identified by <name> to an interface, or associates it with a VLAN ID, in a given direction. The <name> parameter must be the name of an existing MAC ACL.
An optional sequence number may be specified to indicate the order of this mac access list relative to other mac access lists already assigned to this interface and direction. A lower number indicates higher precedence order. If a sequence number is already in use for this interface and direction, the specified mac access list replaces the currently attached mac access list using that sequence number. If the sequence number is not specified for this command, a sequence number that is one greater than the highest sequence number currently in use for this interface and direction is used.
This command specified in 'Interface Config' mode only affects a single interface, whereas the
'Global Config' mode setting is applied to all interfaces. The VLAN keyword is only valid in the
'Global Config' mode. The 'Interface Config' mode command is only available on platforms that support independent per-port class of service queue configuration.
Note: You should be aware that the <out> option may or may not be available, depending on the platform.

IP Access Control List (ACL) Commands
This section describes the commands you use to configure IP ACL settings. IP ACLs ensure that only authorized users have access to specific resources and block any unwarranted attempts to reach network resources.
The following rules apply to IP ACLs:
• Managed switch software does not support IP ACL configuration for IP packet fragments.
• The maximum number of ACLs you can create is hardware dependent. The limit applies to all
ACLs, regardless of type.
• The maximum number of rules per IP ACL is hardware dependent.
• Wildcard masking for ACLs operates differently from a subnet mask. A wildcard mask is in essence the inverse of a subnet mask. With a subnet mask, the mask has ones (1's) in the bit positions that are used for the network address, and has zeros (0's) for the bit positions that are not used. In contrast, a wildcard mask has (0’s) in a bit position that must be checked. A ‘1’ in a bit position of the ACL mask indicates the corresponding bit can be ignored. access-list
This command creates an IP Access Control List (ACL) that is identified by the access list number, which is 1-99 for standard ACLs or 100-199 for extended ACLs.
IP Standard ACL:

If the sequence number is not specified by the user, a sequence number that is one greater than the highest sequence number currently in use for this interface and direction is used. Valid range is (1 to 4294967295).
IPv6 Access Control List (ACL) Commands
This section describes the commands you use to configure IPv6 ACL settings. IPv6 ACLs ensure that only authorized users have access to specific resources and block any unwarranted attempts to reach network resources.
The following rules apply to IPv6 ACLs:
• The maximum number of ACLs you create is 100, regardless of type.
• The system supports only Ethernet II frame types.
• The maximum number of rules per IPv6 ACL is hardware dependent.
ipv6 access-list
This command creates an IPv6 Access Control List (ACL) identified by <name>, consisting of classification fields defined for the IP header of an IPv6 frame. The <name> parameter is a casesensitive alphanumeric string from 1 to 31 characters uniquely identifying the IPv6 access list.
If an IPv6 ACL by this name already exists, this command enters IPv6-Access-List config mode to allow updating the existing IPv6 ACL.
Note: The CLI mode changes to IPv6-Access-List Config mode when you successfully execute this command.

Global Config
{deny | permit} (IPv6)
This command creates a new rule for the current IPv6 access list. Each rule is appended to the list of configured rules for the list.
Note: The ‘no’ form of this command is not supported, since the rules within an IPv6
ACL cannot be deleted individually. Rather, the entire IPv6 ACL must be deleted and respecified.
Note: An implicit ‘deny all’ IPv6 rule always terminates the access list.
A rule may either deny or permit traffic according to the specified classification fields. At a minimum, either the ‘every’ keyword or the protocol, source address, and destination address values must be specified. The source and destination IPv6 address fields may be specified using the keyword ‘any’ to indicate a match on any value in that field. The remaining command parameters are all optional, but the most frequently used parameters appear in the same relative order as shown in the command format.

The assign-queue parameter allows specification of a particular hardware queue for handling traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where n is the number of user configurable queues available for the hardware platform. The assign-queue parameter is valid only for a permit rule.
The mirror parameter allows the traffic matching this rule to be copied to the specified <unit/ slot/port> , while the redirect parameter allows the traffic matching this rule to be forwarded to the specified <unit/slot/port>. The assign-queue and redirect parameters are only valid for a permit rule.

IPv6-Access-List Config ipv6 traffic-filter
This command either attaches a specific IPv6 ACL identified by <name> to an interface or associates with a VLAN ID in a given direction. The <name> parameter must be the name of an existing IPv6 ACL.
An optional sequence number may be specified to indicate the order of this mac access list relative to other IPv6 access lists already assigned to this interface and direction. A lower number indicates higher precedence order. If a sequence number is already in use for this interface and direction, the specifiedIPv6 access list replaces the currently attached IPv6 access list using that sequence number. If the sequence number is not specified for this command, a sequence number that is one greater than the highest sequence number currently in use for this interface and direction is used.
This command specified in Interface Config mode only affects a single interface, whereas the
Global Config mode setting is applied to all interfaces. The vlan keyword is only valid in the
Global Config mode. The Interface Config mode command is only available on platforms that support independent per-port class of service queue configuration.
Note: You should be aware that the <out> option may or may not be available, depending on the platform.

Auto-Voice over IP Commands
This section describes the commands you use to configure Auto-Voice over IP (VoIP) commands.
The Auto-VoIP feature explicitly matches VoIP streams in Ethernet switches and provides them with a better class-of-service than ordinary traffic. When you enable the Auto-VoIP feature on an interface, the interface scans incoming traffic for the following call-control protocols:
• Session Initiation Protocol (SIP)
• H.323
• Skinny Client Control Protocol (SCCP)
When a call-control protocol is detected, the switch assigns the traffic in that session to the highest
CoS queue, which is generally used for time-sensitive traffic.

Auto Install Commands
This section describes the Auto Install Commands. Auto Install is a software feature which provides for the configuration of a switch automatically when the device is initialized and no configuration file is found on the switch. The Auto Install process requires DHCP to be enabled by default in order for it to be completed. The downloaded config file is not automatically saved to startup-config. An administrator must explicitly issue a save request in order to save the configuration. The Auto Install process depends upon the configuration of other devices in the network, including a DHCP or BOOTP server, a TFTP server and, if necessary, a DNS server.
There are three steps to Auto Install:
1. Configuration or assignment of an IP address for the device.
2. Assignment of a TFTP server.
3. Obtain a configuration file for the device from the TFTP server.

show running-config
Use this command to display or capture the current setting of different protocol packages supported on the switch. This command displays or captures commands with settings and configurations that differ from the default value. To display or capture the commands with settings and configurations that are equal to the default value, include the [all] option.
Note: Show running-config does not display the User Password, even if you set one different from the default.
The output is displayed in script format, which can be used to configure another switch with the same configuration. If the optional <scriptname> is provided with a file name extension of
“.scr”, the output is redirected to a script file.
Note: If you issue the show running-config command from a serial connection, access to the switch through remote connections (such as Telnet) is suspended while the output is being generated and displayed.
Note: If you use a text-based configuration file, the show running-config command will only display configured physical interfaces, i.e. if any interface only contains the default configuration, that interface will be skipped from the show running-config command output. This is true for any configuration mode that contains nothing but default configuration. That is, the command to enter a particular config mode, followed immediately by its ‘exit’ command, are both omitted from the show running-config command output (and hence from the startup-config file when the system configuration is saved.)
If option <changed> is used, this command displays/capture commands with settings/ configurations that differ from the default value.

[noval]
| sftp|scp://<username>@<ipaddr>|<ipv6address>|<filepath>|<filename>}
For TFTP, SFTP and SCP, the <ipaddr|hostname> parameter is the IP address or host name of the server, <filepath> is the path to the file, and <filename> is the name of the file you want to upload or download. For SFTP and SCP, the <username> parameter is the username for logging into the remote server via SSH.
Note: <ip6address> is also a valid parameter for routing packages that support IPv6.
For platforms that support a USB device, the
copy
command can be used to transfer files from and to the USB device. The syntax for the USB file is:
usb://<filename>
. The
USB device can be either a source or destination in the copy command. It cannot be used as both source and destination in a given
copy
command.

Packet Capture Commands
Packet capture commands assist in troubleshooting protocol-related problems with the management CPU. The packets to and from the management CPU can be captured in an internally allocated buffer area for export to a PC host for protocol analysis. Public domain packet analysis tools like Ethereal can be used to decode and review the packets in detail. Capturing can be performed in a variety of modes, either transmit-side only, receive-side only, or both. The number of packets captured will depend on the size of the captured packets.

Configuring the Switch Management CPU
To manage the switch via the web GUI or telnet, an IP address needs to be assigned to the switch management CPU. Whereas there are CLI commands that can be used to do this, ezconfig simplifies the task. The tool is applicable to all NETGEAR 7000-series managed switches, and allows you to configure the following parameters:
1. The administrator’s user password and administrator-enable password
2. Management CPU IP address and network mask
3. System name and location information
The tool is interactive and uses questions to guide you through the steps required to perform its task. At the end of the session, it will ask you if you want to save the changed information. To see exactly what has been changed by ezconfig at the end of the session, use the show running-config command.
To perform any switch configuration other than the items listed above, use other CLI commands or the Web GUI.
ezconfig
This command sets the IP address, subnet mask and gateway of the device. The IP address and the gateway must be on the same subnet.

Privileged EXEC network mac-address
This command sets locally administered MAC addresses. The following rules apply:
• Bit 6 of byte 0 (called the U/L bit) indicates whether the address is universally administered
(b'0') or locally administered (b'1').
• Bit 7 of byte 0 (called the I/G bit) indicates whether the destination address is an individual address (b'0') or a group address (b'1').
• The second character, of the twelve character macaddr, must be 2, 6, A or E.
A locally administered address must have bit 6 On (b'1') and bit 7 Off (b'0').

Type
If desired, a locally administered MAC address can be configured for in-band connectivity.
To take effect, 'MAC Address Type' must be set to 'Locally Administered'. Enter the address as twelve hexadecimal digits (6 bytes) with a colon between each byte. Bit 1 of byte 0 must be set to a 1 and bit 0 to a 0, i.e. byte 0 should have the following mask 'xxxx xx10'. The MAC address used by this bridge when it must be referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge. However it is only required to be unique. When concatenated with dot1dStpPriority a unique BridgeIdentifier is formed which is used in the Spanning
Tree Protocol.
The MAC address which should be used for in-band connectivity. The choices are the burned in or the Locally Administered address. The factory default is to use the burned in
MAC address.

User Account Commands
This section describes the commands you use to add, manage, and delete system users. The 7000 series software has two default users: admin and guest. The admin user can view and configure system settings, and the guest user can view settings.
Note: You cannot delete the admin user. There is only one user allowed with read/write privileges. You can configure up to five read-only users on the system.
username
Use this command to add a new user to the local user database. The default privilege level is 1.
Using the encrypted keyword allows the administrator to transfer local user passwords between devices without having to know the passwords. When the password parameter is used along with encrypted parameter, the password must be exactly 128 hexadecimal characters in length. If the password strength feature is enabled, this command checks for password strength and returns an appropriate error if it fails to meet the password strength criteria. Giving the optional parameter override-complexity-check disables the validation of the password strength.

aaa authentication login
This command is used to set authentication at login. The default and optional list names that you create with the
aaa authentication login
command are used with the
login authentication
command. Create a list by entering the
aaa authentication login list-name method
command for a particular protocol, where
list-name
is any character string used to name this list. The
method
argument identifies the list of methods that the authentication algorithm tries, in the given sequence. The additional methods of authentication are used only if the previous method returns an error, not if it fails.
An example of a method that returns an error is if a RADIUS server is not present, and an example of a method failing is when a RADIUS server cannot authenticate the client. If
‘local’ method is listed first, since local authentication is always available, it only has the fail condition, not error. As such, if ‘local’ method is the first in the list, no other method will be tried.
To ensure that the authentication succeeds even if all methods return an error, specify
none
as the final method in the command line. For example if
none
is specified as an authentication method after
radius
, no authentication is used if the radius server is down.

the authenticating and accounting servers are configured without a name, the command uses the
‘Default_RADIUS_Auth_Server’ and ‘Default_RADIUS_Acct_Server’ as the default names, respectively. The same name can be configured for more than one authenticating servers and the name should be unique for accounting servers. The RADIUS client allows the configuration of a maximum 32 authenticating and accounting servers.
If you use the <auth> parameter, the command configures the IP address or hostname to use to connect to a RADIUS authentication server. You can configure up to 3 servers per RADIUS client.
If the maximum number of configured servers is reached, the command fails until you remove one of the servers by issuing the “no” form of the command. If you use the optional <port> parameter, the command configures the UDP port number to use when connecting to the configured RADIUS server. The <port> number range is 1 - 65535, with 1812 being the default value.
Note: To re-configure a RADIUS authentication server to use the default UDP <port>, set the <port> parameter to 1812.
If you use the <acct> token, the command configures the IP address or hostname to use for the
RADIUS accounting server. You can only configure one accounting server. If an accounting server is currently configured, use the “no” form of the command to remove it from the configuration.
The IP address or hostname you specify must match that of a previously configured accounting server. If you use the optional <port> parameter, the command configures the UDP port to use when connecting to the RADIUS accounting server. If a <port> is already configured for the accounting server, the new <port> replaces the previously configured <port>. The <port> must be a value in the range 0 - 65535, with 1813 being the default.
Note: To re-configure a RADIUS accounting server to use the default UDP <port>, set the <port> parameter to 1813.

Description
The DNS name of the server.
The port number to use to connect to the specified RADIUS server.
The alias name to identify the server.
no radius server host
The no version of this command deletes the configured server entry from the list of configured
RADIUS servers. If the RADIUS authenticating server being removed is the active server in the servers that are identified by the same server name, then the RADIUS client selects another server for making RADIUS transactions. If the 'auth' token is used, the previously configured RADIUS authentication server is removed from the configuration. Similarly, if the 'acct' token is used, the previously configured RADIUS accounting server is removed from the configuration. The
<ipaddr|dnsname> parameter must match the IP address or dns name of the previously configured RADIUS authentication / accounting server.
Format
Mode no radius server host {auth | acct} {<ipaddr|dnsname>}

radius server key
This command configures the key to be used in RADIUS client communication with the specified server. Depending on whether the 'auth' or 'acct' token is used, the shared secret is configured for the RADIUS authentication or RADIUS accounting server. The IP address or hostname provided must match a previously configured server. When this command is executed, the secret is prompted.

This command specifies a configured server that should be the primary server in the group of servers which have the same server name. Multiple primary servers can be configured for each number of servers that have the same name. When the RADIUS client has to perform transactions with an authenticating RADIUS server of specified name, the client uses the primary server that has the specified server name by default. If the RADIUS client fails to communicate with the primary server for any reason, the client uses the backup servers configured with the same server name. These backup servers are identified as the ‘Secondary’ type.

TACACS+ Commands
TACACS+ provides access control for networked devices via one or more centralized servers.
Similar to RADIUS, this protocol simplifies authentication by making use of a single database that can be shared by many clients on a large network. TACACS+ is based on the TACACS protocol
(described in RFC1492) but additionally provides for separate authentication, authorization, and accounting services. The original protocol was UDP based with messages passed in clear text over the network; TACACS+ uses TCP to ensure reliable delivery and a shared key configured on the client and daemon server to encrypt all messages.
tacacs-server host
Use the tacacs-server host command in Global Configuration mode to configure a
TACACS+ server. This command enters into the TACACS+ configuration mode. The <ip- address|hostname> parameter is the IP address or hostname of the TACACS+ server. To specify multiple hosts, multiple tacacs-server host commands can be used.

Global Config tacacs-server key
Use the tacacs-server key command to set the authentication and encryption key for all
TACACS+ communications between the switch and the TACACS+ daemon. The <key- string> parameter has a range of 0 - 128 characters and specifies the authentication and encryption key for all TACACS communications between the switch and the TACACS+ server.
This key must match the key used on the TACACS+ daemon.
Text-based configuration supports TACACS server’s secrets in encrypted and non-encrypted format. When you save the configuration, these secret keys are stored in encrypted format only. If you want to enter the key in encrypted format, enter the key along with the encrypted keyword. In the show running config command’s display, these secret keys are displayed in encrypted format.
You cannot show these keys in plain text format.

Configuration Scripting Commands
Configuration Scripting allows you to generate text-formatted script files representing the current configuration of a system. You can upload these configuration script files to a PC or UNIX system and edit them. Then, you can download the edited files to the system and apply the new configuration. You can apply configuration scripts to one or more switches with no or minor modifications.
Use the show running-config command (see
“show running-config” on page 6-15 ) to
capture the running configuration into a script. Use the copy command (see
to transfer the configuration script to or from the switch.
You should use scripts on systems with default configuration; however, you are not prevented from applying scripts on systems with non-default configurations.
Scripts must conform to the following rules:
• Script files are not distributed across the stack, and only live in the unit that is the master unit at the time of the file download.
• The file extension must be “.scr”.
• A maximum of ten scripts are allowed on the switch.
• The combined size of all script files on the switch shall not exceed 2048 KB.
• The maximum number of configuration file command lines is 2000.
You can type single-line annotations at the command prompt to use when you write test or configuration scripts to improve script readability. The exclamation point (!) character flags the beginning of a comment. The comment flag character can begin a word anywhere on the command line, and all input following this character is ignored. Any command line that begins with the “!” character is recognized as a comment line and ignored by the parser.
The following lines show an example of a script:

Captive Portal Commands
The Captive Portal feature is a software implementation that blocks clients from accessing the network until user verification has been established. Verification can be configured to allow access for both guest and authenticated users. Authenticated users must be validated against a database of authorized Captive Portal users before access is granted.
The Authentication server supports both HTTP and HTTPS web connections. In addition, Captive
Portal can be configured to use an optional HTTP port (in support of HTTP Proxy networks). If configured, this additional port is then used exclusively by Captive Portal. Note that this optional port is in addition to the standard HTTP port 80 which is currently being used for all other web traffic.
