Entering a specific command allows switching from one mode to another. Entering the "exit" command returns program control to the previous mode.
Entering "end" command or pressing [Ctrl] and [Z], or [C] simultaneously in the global configuration, interface edit or terminal edit mode transfers program control to the administrator EXEC mode.
An example is given below.
Login: admin password: ******** xg> enable xg# configure terminal xg(config)# interface port 1 xg(config-if)# exit xg(config)# exit xg# copy running-config startup-config xg# exit
Switch to operator EXEC mode by performing a login operation.
By default, the login username is "admin" and password "password".
Use the "enable" command to switch to administrator EXEC mode.
Use the "configure terminal" command to switch to global configuration mode.
Use the "interface" command to switch to interface edit mode.
Use the "exit" command to return to global configuration mode.
Use the "exit" command to return to administrator EXEC mode.
Copy the current configuration file in memory to the startup-config in the nonvolatile memory.
User is logged out and session is disconnected.
Multiple users can use the operator and administrator EXEC modes concurrently. (Up to 5 terminals)
Only one terminal can switch to global configuration, interface edit or terminal edit modes at a time. It is not possible for multiple terminals to simultaneously switch to global configuration mode.
Pressing [Ctrl] and [C] simultaneously in the global configuration, interface edit or terminal edit mode transfers program control to the administrator EXEC mode when “- -more- -“ is displayed in the last line in the console screen.

2.1.3 startup-config and running-config
The configuration information is saved to startup-config and running-config files.
This section describes the functions of the startup-config and running-config files. startup-config
Startup-config is the configuration file that stores the environment settings that are enabled upon device startup. The startup-config is saved in non-volatile memory and read the next time the device is reset or power cycled. running-config
Running-config is a file stored in volatile memory that represents the operating environment of the current running system. The information stored in the running-config file will be lost when the system is restarted.
To assure the system configuration that is active in the current running-config file is enabled the next time the system is started, use the "copy" command to save it to the startup-config file. xg# copy running-config startup-config
The contents of the startup-config and running-config match immediately after the device is started.
How to upload and save the startup-config and running-config files
This procedure can only be run from a host computer running a TFTP server and connected via a telnet or ssh session. To upload the configuration information to the TFTP server, run the "show" command. xg# show running-config | tftp HOST REMOTE-FILE or xg# show startup-config | tftp HOST REMOTE-FILE
How to download startup-config
To download the configuration information that was uploaded to the TFTP server as startup-config, run the "copy" command. xg# copy tftp HOST REMOTE-FILE startup-config
To enable the settings downloaded to the startup-config file, restart the device using the
"reset" command.
Be sure to upload the contents of the startup-config file to a TFTP server because the contents could be lost if the startup-config file is accidentally overwritten.
Refer to "
Uploading/Downloading a Configuration File " for details on uploading and downloading
configurations.

2.2 Using the CLI
2.2.1 How to Enter Commands
Command Entry Format
Separate each command, subcommand and argument with a single space.
<command> <subcommand> <argument 1> <argument 2> ... (" " indicates a space.) xg(config)# management-interface ip 192.168.1.10/24 default-gw 192.168.1.150 xg(config)# management-interface dns-server 192.168.1.150
Characters that can be entered:
− Any letter (A-Z, a-z) and digit (0-9)
− Space (ASCII code: 0x20)
− Symbols: !, ". #, $, %, `, ', (, ), _, -, ~, ^, ¥, {, }, :, +, ,, ., @, =, [, ], &, *, ;, /, ?, |, >
Command and option separators are recognized as one or more space characters (ASCII code:
0x20). Enclose a parameter in quotes if it contains a blank space.
The commands are not case-sensitive. Note that some entries (password, etc.) are case-sensitive.
2.2.2 Context-Sensitive Help
Entering a question mark "?" at the command prompt displays a list of commands available for each command mode. A list of command's associated with the keywords and parameters will be displayed.
A list of commands that are available in the current mode
Entering a question mark "?" at the system prompt displays a list of commands and brief descriptions available for the current command mode. xg # ?
Exec commands:
boot-system Change firmware to boot
clear Reset functions
configure Enter configuration mode
copy Copy from one file to another
date Manage the system date and time
delete Delete files on current system
dir List files on current system
:
(The rest is omitted.) xg# _
Word help
Entering a question mark "?" in the middle of a command name, will list the possible command options required to complete the command. The prompt will show the letters previously typed.
Enter the rest of the letters to complete the command entry. xg # co?
Exec commands:
configure Enter configuration mode
copy Copy from one file to another xg# co_
The CLI lists all possible commands that begin with "co".
A list of options that are available in the current entry position
Entering a question mark "?" followed by a space after typing a command name, will cause the CLI to list the possible commands or keywords that may be entered at the current option position. For option 2 and 3 positions, the CLI also lists options that can be entered at these positions. The prompt will show the letters previously typed.
Enter the rest of the letters to complete the command entry. xg# configure ? terminal Configure from the terminal xg# configure _
CLI lists possible options that follow the "configure" command.
The <cr> symbol may appear in the list to indicate that the command can be executed without entering any subsequent options. Parameters enclosed in square brackets can be omitted and, therefore, the <cr> symbol does not appear.

2.2.3 Command Completion
Entering part of a command or option and pressing the [Tab] key, causes the CLI to display the remaining command or option characters. xg# con<TAB>
↓ xg# configure _
For example, the only command that begins with "con" is "configure", so the CLI completes the command name as "configure".
Pressing the [Tab] key, causes the CLI to list all possible commands or option names. xg# co<TAB> configure copy xg# co_
Since there are two commands that begin with "co" - "configure" and "copy" - the CLI lists both commands.
2.2.4 Command Abbreviation
Commands and options can be abbreviated to the minimum number of characters as long as command or option names are unique and forward-match the entered letters. xg# con t
For example, the "configure" command may be abbreviated to "con" because "configure" is the only command that begins with
"con", and "terminal" may be abbreviated to "t" because "terminal" is the only command that begins with "t".
2.2.5 Command-Line Error Messages
The table below shows error messages that appear when a command is incorrectly entered. The "configure terminal" command is used as an example below:
Error Message Explanation
xg# co t
% Ambiguous command: "co t" xg# configure

2.2.10 Filtering show Command Output
This function allows filtering the show command output so lines that only satisfy specific conditions (filter for strings) are displayed. This function is useful in excluding unnecessary information from a large amount of output.
To use it, a "show" command must be followed by a keyword (pipe (|), begin, include or exclude) and a regular expression
(filtering condition).
Syntax show | {begin | include | exclude} regular-expression
Keyword for filtering output Meaning begin exclude include
Begins output starting at the first line that contains matches to given regular expression parameters.
Does not display output lines that contain matches to given regular expression parameters.
Displays output lines that contain matches to given regular expression parameters. xg# show history | begin 2
...skipping
2 configure terminal
3 show running-config
4 show history
5 show history | begin 2 xg# show history | exclude 2
1 enable
3 show running-config
4 show history xg# show history | include 2
2 configure terminal
5 show history | begin 2
Regular expressions are case sensitive.
For example, if "| exclude strings" is entered, lines that include "String" are output, but those that include "strings" are not.
2.2.11 Redirecting show Command Output
Redirect the output of "show" commands to a file in volatile memory using ">" (pipe) or "|” (redirect).
Syntax (To redirect the output of a show command to a file in volatile memory:) show > FILE-NAME show | FILE-NAME
FILE-NAME
Specifies the file name in volatile memory that the output of the command is piped or redirected.
"| tftp" redirects the output of the show command to a file on a TFTP server.
Syntax (Redirect the output of a show command to a file on a TFTP server:) show | tftp HOST REMOTE-FILE
HOST
Specifies the host name or IP address of the TFTP server.
REMOTE-FILE
Specifies the file name in the TFTP server that the output of the command is redirected.
In the following example, the current startup-config is redirected as filename "startup_09302005", the running-config file is redirected as filename "running_09302005", and system information is redirected as filename "system_09302005".
The results of the redirection are confirmed with the "ls" command.
Then, using the "tftp" command, each of these files are moved to the TFTP server. xg# show startup-config > startup_09302005 xg# show running-config > running_09302005 xg# show system information > system_09302005 xg# ls
(ls command output)
Update-time File-size File-name
- 2005/09/30 11:57:27 872 system_09302005
- 2005/09/30 11:54:01 2,310 startup_09302005
- 2005/09/30 11:55:58 2,437 running_09302005 xg# tftp put remote-host1 startup_09302005 restore_startup_09302005 xg# tftp put remote-host1 running_09302005 restore_running_09302005 xg# tftp put remote-host1 system_09302005 restore_system_09302005
In the following example, show command output is redirected to TFTP server "remote-host1" using "| tftp". xg# show startup-config | tftp remote-host1 restore_ startup_09302005 xg# show running-config | tftp remote-host1 restore_running_09302005 xg# show system information | tftp remote-host1 restore_system_09302005

4.1 Basic Switch Functions
This section describes the basic switch functions.
4.1.1 Switching Mode
The device provides the following two switching modes.
Store-and-forward switching mode
After the device finishes receiving a frame, it checks the FCS (Frame Check Sequence) and performs a validity check (on packet size, etc.) before forwarding the frame. If the switch receives a frame with an error frame, it discards it.
Cut-through switching mode
The device transmits the frame to the destination as soon as the first 64 bytes of the frame are received with no errors. Since the device starts transmitting the frame before it receives the entire frame, this mode allows forwarding at low latency.
To change the switching modes, carry out the following procedures in the administrator EXEC mode.
Command
xg# configure terminal xg(config)# bridge forward-mode
{cut-through | store-and-forward }
Task
Switch to global configuration mode.
Select the cut-through (or store-and-forward) for the switching mode. xg(config)# no bridge forward-mode xg(config)# exit
Exit to administrator EXEC mode.
4.1.2 MAC Address Table Management
The MAC address table is a database used for managing the association between address information and destination ports.
The device can learn up to 16384 entries of MAC addresses.
MAC address table management
The device has two methods for MAC address table management.
− SVL(Shared VLAN Learning)
The device learns MAC addresses common to all VLANs. Different VLANs with identical
MAC addresses are treated as identical entries.
− IVL(Independent VLAN Learning)
The device learns MAC addresses separately for each VLAN. Identical MAC addresses with different VLANs are treated as separate entries.
To change the MAC address table management modes, carry out the following procedures in the management EXEC mode.
Command
xg# configure terminal xg(config)# bridge learn-mode { ivl | svl } xg(config)# no bridge learn-mode
Task
Switch to the global configuration mode.
Select IVL or SVL for the MAC address table management mode. xg(config)# exit xg# copy running-config startup-config xg# reset
Exit to administrator EXEC mode.
Save the current settings of the device to nonvolatile memory.
If the MAC address table management mode is changed, the new setting becomes enabled after the device is restarted. xg(config)# interface port 1 2 3 xg(config-if)# suppress-address-learning
Dynamic MAC address learning
The device dynamically learns MAC addresses from received frames. If MAC addresses are not refreshed before the aging time expires, they will be removed from the MAC address table.
To disable the dynamic learning, carry out the following procedures in the administrator
EXEC mode.
Command
xg# configure terminal xg(config)# interface port range 1 3
Task
Switch to global configuration mode.
Switch to the interface edit mode to specify the port(s) to be configured.
In this example, the global interface configuration mode is selected for ports 1 through 3.
Enable (or disable) the dynamic MAC address learning. xg(config-if)# no suppress-address-learning xg(config-if)# exit xg(config)# exit
Exit to global configuration mode.
Exit to administrator EXEC mode.

XG2000 series User's Guide
Static unicast address
By registering a unicast MAC address with the MAC address table, unicast frames are forwarded to a specified port. Static unicast addresses are not subject to MAC address removal controlled by the aging function.
To register, change or delete a static unicast address, carry out the following procedures in the administrator EXEC mode.
Command
xg# configure terminal xg(config)# bridge mac-address-table
static MAC [vlan <1-4094>]
Task
Switch to global configuration mode.
Register a static unicast address and destination port with the
MAC address table (or remove them from it).
{[port <1-20>] | [agg-port <1-10>]} xg(config)# no bridge mac-address-table
static MAC [vlan <1-4094>] xg(config)# exit
Exit to administrator EXEC mode.
Static multicast address
By registering a multicast MAC address with the MAC address table, a specific multicast frame will be forwarded to a designated port.
To register, change or delete a multicast address, carry out the following procedures in the administrator EXEC mode.
Command
xg# configure terminal xg(config)# bridge mac-address-table
static MAC [vlan <1-4094>]
[port <1-20> [<1-20> ]]
Task
Switch to global configuration mode.
Register (or remove) a static multicast address table and destination port.
For a multicast MAC address, multiple ports can be specified.
[agg-port <1-10> [<1-10> ]] xg(config)# no bridge mac-address-table
static MAC [vlan <1-4094>] xg(config)# exit
Exit to administrator EXEC mode.
4.1.3 Jumbo Frame Support
The device can transmit jumbo frames of up to 16KB (16128 bytes).
To configure jumbo frame support, carry out the following procedure in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# bridge jumbo-frame
Switch to global configuration mode.
Enable (or disable) jumbo frame support.
[{9216 | 12288 | 15360 | 16128}] xg(config)# no bridge jumbo-frame xg(config)# exit
Exit to administrator EXEC mode.
4.1.4 Flow Control
Flow control is a function that prevents frame loss when the receive buffer in the switch overflows due to temporary traffic overload by using a PAUSE frame.
When the device receives a PAUSE frame, it temporarily stops sending frames at the receive port. If the receive buffer overflows, it is possible to restrict frame transmission from the connected device by sending a PAUSE frame.
For each port, it is possible to select whether or not to send a PAUSE frame. Select the mode depending on whether the destination responds to a PAUSE frame or not.
To change the flow control mode, carry out the following procedures in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# interface port 1 2 3 xg(config)# interface port range 1 3 xg(config-if)# flowcontrol
Switch to global configuration mode.
Switch to the interface edit mode to specify the port(s) to be configured for flow control.
In this example, the global interface configuration mode is selected for ports 1 through 3.
Set the flow control mode.
{ only-receive | send-receive } xg(config-if)# exit xg(config)# exit
Exit to global configuration mode.
Exit to administrator EXEC mode.

4.1.5 Storm Control
The device discards broadcast frames when the number of received broadcast frames are over a given threshold to prevent unnecessary waste of bandwidth due to retained broadcast frames on the network. This function is called "Storm Control".
For each port, it is possible to configure storm control.
When broadcast frames are discarded by storm control, error logs are output, and storm control logging is disabled. To re-enabled logging, these violations must be cleared with "clear violation".
To configure storm control, carry out the following procedures in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# interface port 1 2 3 xg(config)# interface port range 1 3 xg(config-if)# storm-control xg(config-if)# exit xg(config)# exit
Switch to global configuration mode.
Switch to the interface edit mode to specify the port(s) to be configured for storm control.
In this example, the global interface configuration mode is selected for ports 1 though 3.
Enable storm control.
Exit to global configuration mode.
Exit to administrator EXEC mode.
4.1.6 Port Security
Port security blocks connections attempted by unregistered hosts. When a host MAC address is registered, the device receives only those frames that use registered source addresses.
For each port, it is possible to configure port security. To register a MAC address for a host, use the "bridge mac-address-table static" command. The port that the host is connected must be registered as a member port. In Independent VLAN Learning mode, this must be done for all VLANs that permit transmission.
Either of the following two modes can be specified for a security-violating (unregistered) frame the device receives.
− Restrict mode
Filters violating frames only, forwarding permitted frames.
− Shutdown mode
Filters all frames upon reception of a violating frame, and the port goes link down.
Once a security violation is detected, an error log is recorded. No further detection of a violating frame will cause an error log to be recorded until security violations are reset by "clear violation".
To configure port security, carry out the following procedures in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# interface port 1 2 3 xg(config)# interface port range 1 3 xg(config-if)# port-security violation
{restrict | shutdown} xg(config-if)# clear violation xg(config-if)# exit xg(config)# exit
Switch to global configuration mode.
Switch to the interface edit mode to specify the port(s) to be configured for port security.
In this example, the global interface configuration mode is selected for ports 1 though 3.
Enable Port Security.
Clear security violations.
Exit to global configuration mode.
Exit to administrator EXEC mode.
4.1.7 Ingress Rate Control
It is possible to set an ingress rate-limiting value for each port in approximately 40Mbps increments.
To set an ingress rate-limiting value, carry out the following procedures in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# interface port 1 2 3 xg(config)# interface port range 1 3
Switch to global configuration mode.
Switch to the interface edit mode to specify the port(s) to be configured for ingress rate control.
In this example, the global interface configuration mode is selected for ports 1 though 3. xg(config-if)# ingress-bandwidth <40-10000>
Specify an ingress rate limiting value. xg(config-if)# exit xg(config)# exit
Exit to global configuration mode.
Exit to administrator EXEC mode.
The ingress rate is measured at 100us time intervals. Should burst transfers take place at intervals of 100us or over, the ingress rate the device actually allows may be less than the specified value.

4.2 Port Mirroring
It is possible to monitor the traffic by mirroring the frames sent or received by a port to another port. Multiple ports may not be mirrored to one port. However, multiple ports may be mirrored.
To configure port mirroring, carry out the following procedure in the administrator EXEC mode.
Command
xg# configure terminal xg(config)# mirror monitored-port <1-20>
[rx-mirroring-port <1-20>]
Task
Switch to global configuration mode.

4.3 Link Pass Through
Link pass through is a function that monitors the status of a specified port link and notifies the device connected to the port via link status notification of the link status of a monitored port by synchronizing the monitored port with the link status on the port.
This function allows the device to notify the port, after link status notification, of a link fault if detected at the monitored port.
Link pass through communicates the link fault status to the other port by sending a remote fault (RF) signal, as prescribed in
IEEE802.3ae LFS (Link Fault Signaling). When the link status of the monitored port is restored to normal, the other port is also restored to normal, thereby restoring the network link.
To configure Link pass through, carry out the following procedure in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# link-pass-through { monitored-port
<1-20> | monitored-agg-port <1-10>}
Switch to global configuration mode.
Set the relationship between the ports to be monitored and ports link status notification were sent.
[domino-port <1-20> [<1-20> ]]
[domino-agg-port <1-10> [<1-10> ]] xg(config)# exit
Exit to administrator EXEC mode.

4.4 Link Aggregation
Link aggregation is a function that combines multiple ports into a single logical link. A set of ports that comprise a logical link is called an aggregation group.
Link aggregation provides:
Increased bandwidth
By grouping multiple physical ports into a single logical link (an aggregation group), network traffic (data sent and received) will be balanced across the physical ports, thereby providing increased bandwidth.
Redundancy
Multiplexing ports allows uninterrupted network operations should one of the multiple links fail. Since the link status of the logical aggregation groups remains unchanged, there are no fluctuations in network traffic, the effect of a fault having been minimized.
Up to 10 ports can be used to create a single link aggregation group using link aggregation. Up to 10 aggregation groups can be created.

4.4.1 Configuring Link Aggregation
Either static or dynamic (also known as LACP) configuration can be selected for Link Aggregation.
Static configuration
Configures aggregation groups statically.
LACP
Configures link aggregation using Link Aggregation Control Protocol (LACP). The LACP is a switch-to-switch control protocol that enables dynamic configuration of aggregation groups and is standardized by the IEEE802.3ad. The LACP facilitates load balancing across the individual links aggregated between the devices connected.
Either "active" or "passive" LACP mode can be selected.
− active
The device starts LACP negotiation. Since the active mode allows the reception of LACP control frames, it is possible to direct the device in "active" mode.
− passive
The device responds to LACP control frames but does not start LACP negotiation.
To configure static link aggregation, carry out the following procedure in the administrator EXEC mode.
Command Task
xg# configure terminal
Switch to global configuration mode. xg(config)# link-aggregation agg-port <1-10>
protocol none port <1-20> <1-20> xg(config)# interface agg-port <1-10> xg(config-agg)# port-vlan-id vlan 2 xg(config-agg)# exit xg(config)# exit
Assign a number to the aggregation group to be created
(agg-port) and the port numbers assigned to the link aggregation.
Specify "none" for static configuration.
To change the setting of the aggregation group created, switch to the interface edit mode for the aggregation group and specify the "interface agg-port" requiring change.
The prompt changes to "config-agg".
(Optional)
Change the setting of the aggregation group as required. In this example, default VLAN ID is set to 2.
Exit to global configuration mode.
Exit to administrator EXEC mode.
To configure LACP link aggregation, carry out the following procedure in the administrator EXEC mode.
Command
xg# configure terminal
Task
Switch to global configuration mode. xg(config)# link-aggregation agg-port <1-10>
protocol lacp lacp-mode {active | passive }
port <1-20> <1-20> xg(config)# interface agg-port <1-10> xg(config-agg)# port-vlan-id vlan 2 xg(config-agg)# exit xg(config)# exit
Assign a number to the aggregation group to be created
(agg-port) and the port numbers assigned to the link aggregation.
Specify "lacp" for LACP link aggregation. Specify the desired negotiation operational mode in "lacp-mode".
To change the setting of the aggregation group created, switch to the interface edit mode for the aggregation group and specify the "interface agg-port" requiring change.
The prompt changes to "config-agg".
(Optional)
Change the settings of the aggregation group as required. In this example, default VLAN ID is set to 2.
Exit to global configuration mode.
Exit to administrator EXEC mode.

XG2000 series User's Guide
4.4.2 Frame Distribution Methods in Link Aggregation
How frames are distributed across physical ports that make up an aggregation group are determined by the contents of a frame (source and destination MAC addresses).
There are three ways to specify how frames are distributed:
Frame distribution based on destination MAC address (dst-mac)
The destination port is determined based on the destination MAC address of the frames.
Frame distribution based on source MAC address (src-mac)
The destination port is determined based on the source MAC address of the frames.
Frame distribution based on destination and source MAC addresses (dst-src-mac)
The destination port is determined based on the destination and source MAC addresses of the frames.
If there are too few MAC addresses to be distributed across an aggregation group, the distribution of frames across the destination ports tends to become biased. To reduce such bias, use a distribution method that uses more MAC addresses.
For example, if a server is connected to an aggregation group and a client is connected to a different port, the "src-mac" or "dst-src-mac" parameters are recommended.
To set a distribution method, carry out the following procedure in the administrator EXEC mode.
Command
xg# configure terminal
Task
Switch to global configuration mode. xg(config)# link-aggregation agg-port <1-10> protocol {none | lacp}
Specify a distribution method in the load-balance parameter of the "link-aggregation" command. load-balance dst-mac|src-mac|dst-src-mac} port <1-20> <1-20> xg(config)# exit
Exit to administrator EXEC mode.
4.4.3 The Number of Ports That Require Linkup
It is possible to specify the number of ports that enable a linkup state for an aggregation group. If the number of active ports that make up an aggregation group in a linkup state is less than the specified number of ports, the aggregation group changes to a linkdown state.
For static link aggregation
If the number of ports that make up an aggregation group in a linkup state no longer satisfies the specified number of ports, the aggregation group changes to a linkdown state.
For LACP link aggregation
If the number of ports that make up an established LACP aggregation group changes, the aggregation group reverts to a linkdown state.
To set the number of ports in the aggregation group, carry out the following procedure in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# link-aggregation agg-port
<1-10>
protocol {none | lacp} minimum-port <1-20>
Switch to global configuration mode.
Specify the required number of ports in "minimum-port" parameter of the "link-aggregation" command.
The default value for "minimum-port" parameter is 1.
port <1-20> <1-20> xg(config)# exit
Exit to administrator EXEC mode.

4.4.4 Notes on Link Aggregation
The smallest port number in an aggregation group serves as the master port.
Port settings established after defining an aggregation group inherit the same settings as those of the master port, with some exceptions. The settings that are not inherited from the master port are.
"link-pass-through"
Settings for these ports are cleared.
The information registered in MAC address table
All addresses related to ports configured are cleared.
"spanning-tree port-path-cost"
Port-path-cost will be re-adjusted to match the new configuration.
When changing the port settings for aggregation groups that have already been created, the aggregation group changes to a linkdown state, and then to a linkup state if one of the following conditions are satisfied.
A master port was removed
A master port changed
The "protocol" or "lacp-mode" parameter changed

4.5 Uplink Filter
When an uplink domain is defined, the domain's uplink domain ports filter (drops) multicast, broadcast and unlearned (flooding) unicast frames from non-membership downlink ports. However it does not filter learned unicast frames that are forwarded based on the MAC address table.
The uplink filter is useful in configuring large networks with multiple paths, such as a fat tree network, by cascading multiple
XG-series switches.
To configure an uplink filter, specify an uplink domain whose membership consists of one or more downlink ports and one or more uplink ports. For example, in a fat tree network, an uplink domain is configured such that ports connected to switches are designated as uplink ports, and leaf nodes as downlink ports. The uplink domain will then block multicast, broadcast and flooding unicast frames to other uplink domains configured within the switch and only distribute traffic from the downlink to the uplink ports within that domain.
If an uplink filter is specified to have multiple uplink ports, link aggregation and redundancy are provisioned within that domain.
The uplink filter differs from link aggregation in that the uplink ports within the uplink domain can be connected to different switches or equipment to ensure redundancy within the various uplink ports.
36/288
All Rights Reserved, Copyright (C) PFU LIMITED 2008
XG2000 series User's Guide
When specifying multiple uplink ports within an uplink domain, frame distribution among the uplink ports is performed equally from port to port and not by type of frame. Frame distribution changes automatically when a fail-over or fail-back occurs, thereby providing uplink redundancy.

4.6 Spanning Tree Protocol (STP)
The Spanning Tree Protocol (STP) is a function that prevents loops from occurring on a network. It is also possible to provide network redundancy by intentionally creating a loop.
STP exclusively uses only one active path between network devices, and shuts out other paths, to avoid network loops. An active path is selected by comparing path costs defined on each path. After the comparison, the lowest cost path will be selected. If the selected path becomes disabled, STP will activate the lowest cost path amongst the paths remaining.
The device supports IEEE802.1w RSTP (Rapid Spanning Tree Protocol). The RSTP is upward compatible with IEEE802.1D
STP (Spanning Tree Protocol) and serves as a STP if the destination device only supports STP.

4.6.1 Port Roles Based on Spanning Tree
RSTP assigns one of these port roles to individual ports:
Root port
Provides the best path (lowest cost) when the switch forwards packets to the root switch.
Designated port
Connects to the designated switch toward the leaves of the spanning tree. The port specified connecting to the designated port serves as a root port.
Alternate Port
The alternative port with the second lowest path cost. In the event that the root port goes to a linkdown state, the alternate port serves as the root port. It does not always send or receive frames while in the blocking state.
Backup Port
Provides an alternative path to that specified. In the event that the specified port goes into a linkdown state, the backup port serves as the new designated port. It does not always send or receive frames while it is in the blocking state.
Disabled Port
Disabled port, it does not send or receive any frames.
4.6.2 Spanning Tree Protocol Port States
The port states defined by the STP are:
Discard

4.7 VLAN
VLAN (Virtual LAN) is a technology that divides a single network into virtually separated networks.
VLANs are separate logical networks within one physical network. A VLAN capable switch can change and define new LAN network configurations without changing physical cable connections. This creates a flexible and extensible network system.
The device provides for port-based or tag-based (IEEE802.1Q) VLANs.
4.7.1 Port-Based VLAN
Port-based VLAN is a method for configuring VLAN membership on a port basis. Forwarding is based on the destination MAC addresses and related port. xg(config)# vlan-statistics collection <1-4094>
[ <1-4094> ] xg(config)# interface port 1 2 3
(interface port range 1 3) xg(config-if)# port-vlan-id vlan <1-4094> xg(config-if)# ingress-filter tagged-frame xg(config-if)# ingress-filter untagged-frame xg(config-if)# exit xg(config)# exit xg# show interface xg# show vlan
To configure a port-based VLAN, carry out the following procedures in the administrator EXEC mode.

4.7.2 Tag-Based (IEEE802.1Q) VLAN
Tag-based VLAN is a method of configuring VLANs so that the frame forwarding decision is based on a tag in the MAC header identifying the VLAN membership. 4 bytes of additional data in the header, called a VLAN tag, identifies the VLAN frame ownership. Using a VLAN tag enables configuring a single physical link that shares multiple VLANs.
The device’s tag-based VLAN function is based on the IEEE 802.1Q standard.
The following figure shows an Ethernet frame format including a VLAN tag as specified by the IEEE 802.1Q standard. xg(config)# vlan-statistics collection <1-4094>
[ <1-4094> ] xg(config)# interface port 1 2 3
(interface port range 1 3) xg(config-if)# vlan-member allowed vlan
To configure a tag-based VLAN, carry out the following procedures in the administrator EXEC mode.

4.7.3 Multiple VLAN
With the user-defined VLAN tag protocol identifier, the IEEE 802.1Q standard tag can be replaced with a user-defined VPID, allowing for encapsulation of multiple tags for multiple-tagged VLANs. The standard tag identifier or TPID is 0x8100 as defined in IEEE 802.1Q.
For the frame format, refer to TPID (Tag Protocol Identifier) in "
Using multiple VLAN (also known as double tagging or Q-in-Q) allows a service provider to transparently forward customers'
VLAN traffic even if the service provider assigns customer traffic to different VLANs.
To configure multiple VLAN using a user-defined VLAN tag protocol identifier, carry out the following procedures in the administrator EXEC mode.

4.8 Quality of Service (QoS)
The device provides Quality of Service (QoS) that is based on the IEEE802.1p standard.
The device QoS determines the priority of frames at the ingress side using DiffServ, VLAN tag (including priority tag) or a port's default priority. Their priorities are mapped to 4 output queues. The queues are processed in the order of the QoS priority precedence.
The device priorities available are:
DiffServ
Select QoS using the IPv4 header or DiffServ Code Point included in the IPv6 header.
Default priority
Set a default priority of 0 to 7 for each port.
For frames whose priority was not set (VLAN-untagged frames), the default priority is assigned according to the value of the frame.
Mapping to output queues
The device is equipped with four output queues with different levels (0 to 3). Frames are transmitted in order of output queue priority.
Each priority is mapped to a specified output queue.
To set the default priority and output queue mapping, carry out the following procedure in the administrator EXEC mode.
Command Task
xg# configure terminal xg(config)# interface port 1 2 3 xg(config)# interface port range 1 3 xg(config-if)# qos default-priority <0-7>
Switch to global configuration mode.
Switch to interface edit mode and specify the port(s) to set with a default QoS priority.

4.9 IGMP Snooping
IP multicast is often used to distribute multimedia data, including video and voice, over a network.
A layer 2 switch floods multicast frames, absorbing unnecessary network bandwidth. A layer 3 switch that supports Internet
Group Management Protocol (IGMP) manages multicast groups using IGMP packets. The device controls how IP multicast packets are forwarded to required ports by monitoring IGMP packets generated by layer 3 switches, thereby preventing unnecessary flooding. This function is called "IGMP Snooping".
The device supports IGMP snooping for IGMP v1/v2/v3.
IGMP v3 does not support source IP addressing and filtering.
IGMP snooping and the uplink filter function cannot be used at the same time.
The XG2000 series floods IGMP Report messages. When IGMP v1/v2 is used, it is necessary to connect a device, such as a L3 switch, that supports IGMP snooping between the XG2000 series and the IGMP hosts in order to avoid flooding.
It is necessary to set forward-unregistered-mac or filter-unregistered-mac when IGMP snooping is used.

4.9.1 Registering Group Members
On receiving an IGMP Report message, the device registers a multicast MAC address with the MAC address table for the port that received the IGMP Report message and the connecting multicast router port.
The following figure shows the relationship between the registered IP multicast address and the multicast MAC address.
MAC addresses that are registered with IGMP snooping are between 0100.5E00.0000 and 0100.5E7F.FFFF. An IP multicast address is 32 bits. The first 4 bits are always 1110 followed by 28 bits that represent the IP multicast address information. Of these 28 bits, the lower order 23 bits are mapped to a MAC address and the data in the higher order 5 bits is not used.
Therefore 32 IP multicast addresses are mapped to the same single MAC address.

XG2000 series User's Guide
4.9.2 Removing Group Members
The group members registered by IGMP snooping are removed under the following status.
If after receiving an IGMP Report message for group registration, the group member interval expires before the device receives another IGMP Report message, the switch removes that group member. The default setting for the group member interval is 260 seconds.
If an IGMP Leave message is sent from a host, the multicast router sends out an IGMP Specific Query (GSQ) message to determine that the host has left the group.
If after receiving the IGMP Leave message, the last member query interval expires before the device receives another
IGMP Report message, the switch removes that group member. The default setting for the last member query interval is 2 seconds.

All Rights Reserved, Copyright (C) PFU LIMITED 2008
XG2000 series User's Guide
4.9.3 Managing Group Members
When network congestion causes Leave message loss or there is a host that uses IGMPv1, the multicast router does not receive Leave messages. The multicast router sends out an IGMP General Query message to all hosts (IP address: 224.0.0.1) at intervals (query interval) to determine membership information.
Upon reception of an IGMP General Query message, the host, a member of the group, returns an IGMP Report message to maintain membership in the group.
In consideration of General Query or Report message loss caused by network congestion, it is recommended that the following equation be used to determine the group member interval for the device.
Group member interval = (query interval for multicast router)
× 2 + 10 (seconds)
Since RFC 3376 defines the default query interval for multicast routers as 125 seconds, the device uses 260 seconds for the default group member interval.

XG2000 series User's Guide
4.9.4 IGMP Querier
In a typical network configuration, the multicast router periodically sends out an IGMP General Query message to determine if any of the hosts on the network are members of any multicast groups. Receiving a response from a host ascertains its membership in a multicast group.
IGMP Querier is a function that acts as a proxy for a multicast router when one is not available in a network segment to send an IGMP General Query message to all hosts.
The frequency of Query messages issued is configured using the "ip snooping vlan send-query-count" command.
The frequency of the General Query messages sent (query interval) are automatically calculated by the following equation based on the send query count and the group membership interval.
Query interval = (Group membership interval - 10)/send query count (seconds)
The default setting for the Query interval is 125 seconds.
Upon reception of an IGMP Leave message, the device sends an IGMP Specific Query (GSQ) message to determine that the host is interested in leaving the group.
If an IGMP Specific Query message is sent as many times as specified by the send query count and the host does not respond with an IGMP Report message, that host is removed.
Generally, IGMP Querier uses "0.0.0.0" for the source IP address when sending a Query message.
Since some client software does not return a response for a Query message with the source IP address being set to "0.0.0.0", it is recommended that an address other than "0.0.0.0" be used.
If a multicast router exists on the network segment, the device does not send Query message even if
IGMP Querier is valid.

5.6.6 bridge learn-mode
Function
Sets the MAC address table learning mode.
The device supports two learning modes: SVL (Shared Vlan Learning) and IVL (Independent VLAN Learning).
SVL (Shared VLAN Learning)
Regardless of the VLAN of frame ownership, it is learned as a MAC address entry (mapping of MAC address to port) common to every VLAN.
IVL (Independent VLAN Learning)
A MAC address entry (mapping of MAC address for port) is learned for each VLAN.
Use the no form to return to the default setup.
Prompt
xg(config)#
Command syntax bridge learn-mode { ivl | svl } no bridge learn-mode
Parameter
learn-mode { ivl | svl }

5.6.7 bridge mac-address-table
Function
By registering static MAC addresses to the MAC address table, frames with specific destination MAC addresses can be forwarded to a specified port.
When a unicast static MAC address is registered, dynamic MAC addresses will not be learned, even when frames sent from the same MAC address are received from a different port. Also, by registering multicast static MAC addresses, frames to be sent to specific multicast nodes can be assigned so that they will be forwarded only to the port specified. In this case, set the multicast forwarding mode to "forward-unregistered-mac" or "filter-unregistered-mac" using the "multicast-forwarding" command.
Use the no form to delete registered static MAC addresses.
Prompt
xg(config)#
Command syntax bridge mac-address-table static MAC [ vlan <1-4094> ] [ port <1-20> [ <1-20> ] ]
[ agg-port <1-10> [ <1-10> ] ] no bridge mac-address-table static MAC [ vlan <1-4094> ]
Parameter
static MAC
Specifies static MAC addresses. When a frame with this destination address is received, it will be forwarded to the port specified.
The MAC address format is "HHHH.HHHH.HHHH," a 12-digit hexadecimal number with a period (.) inserted between every four digits.
A unicast MAC address can register the information for only one port in the MAC address table. (As for IVL, one port per VLAN) Therefore, if the same unicast MAC address is already assigned to a different port, the entry will be replaced if the same MAC address and different port are specified in a subsequent “mac-address-table static” command.
A multicast MAC address can registered for multiple ports in the MAC address table. If the same multicast MAC address is already set to a port, subsequent assignments of the MAC address to additional ports will be appended to the address table.
A broadcast address (FFFF.FFFF.FFFF) can be registered to multiple ports. However, the entry will be replaced with subsequent commands registering non-broadcast addresses to the ports previously assigned.
The following reserved multicast addresses, prescribed in IEEE802.1D, cannot be registered.
− In the range of 0180.C200.0000 - 0180.C200.0010
− In the range of 0180.C200.0020 - 0180.C200.002F vlan <1-4094>
Specifies a VLAN to register with the MAC address. Specify a VLAN in the range of 1 to 4094.
This parameter is valid only when the learning mode of the MAC address table is IVL (Independent
Vlan Learning). For SVL (Shared Vlan Learning), this parameter is not necessary. port <1-20> [ <1-20> ]
Specifies the port number for the forwarded frame. This parameter is specified in the range of 1 to the maximum number of ports (=20).
Additionally, when static multicast MAC addresses are registered (including broadcast addresses), multiple ports can be specified by separating the port numbers with a " " (space). agg-port <1-10> [ <1-10> ]
Specifies the aggregation group number for the forwarded frame. This parameter is specified in the range of 1 to 10.
Additionally, when static multicast MAC addresses are registered (including broadcast addresses), multiple aggregation groups can be specified by separating the aggregation group numbers with a " " (space).
Command type
Configuration command
Default
Only broadcast address (FFFF.FFFF.FFFF) is registered.

5.7.2 link-aggregation
Function
Link aggregation is a function wherein multiple ports within a switch act as one logical link (aggregated group). This command is used to set up a link aggregation group.
There are two types of link aggregation: static link and LACP.
Static link aggregation
An aggregation group is created statically.
LACP link aggregation
An aggregation group in compliance with IEEE802.3ad LACP (Link Aggregation Control Protocol) is created. LACP is a control protocol among switches for dynamically assembling an aggregation group.
Use the no form to delete an aggregation group.
Prompt
xg(config)#
Command syntax link-aggregation agg-port <1-10> [protocol {none | lacp}] [lacp-mode {active | passive}]
[load-balance {dst-mac | src-mac | dst-src-mac | vlan | ip-hash}]
[ distribution-parameter <0-3> ]
[minimum-port <1-10>] port <1-20> <1-20> [ <1-20> ] no link-aggregation agg-port <1-10>
Parameter
agg-port <1-10>
Specifies the aggregation group number to create. Specify a number in the range of 1 to 10. protocol {none | lacp}
Specifies the protocol type of the link aggregation.
− none
A static link aggregation group.
− lacp
A link aggregation group using IEEE802.3ad LACP as the control protocol between switches.
When this parameter is omitted, "none" is assumed. lacp-mode {active | passive}
Specifies the operational mode of LACP negotiation.
− active
Negotiation of LACP is started from the device. Also, since the active mode can receive
LACP packets, a connection between two LACP active mode enabled switches is possible.
− passive
The device will be in the passive mode of the LACP protocol. The switch responds to
LACP packets, but will not start negotiation.
This parameter can be specified only when "lacp" is specified as the "protocol" parameter.
When this parameter is omitted, "active" is assumed. load-balance { dst-mac | src-mac | dst-src-mac | vlan | ip-hash }
Specifies the frame distribution method for each port in the aggregation group
− dst-mac
Determines the forwarding destination port, based on the destination MAC address of the frames.
− src-mac
Determines the forwarding destination port, based on the source MAC address.
− dst-src-mac
Determines the forwarding destination port, based on the destination MAC address of a frame and the source MAC address.
− vlan
Determines the forwarding destination port, based on VLAN membership.
− Ip-hash
Determines the forwarding destination port, based on the IP hash information.
When this parameter is omitted, "dst-mac" is assumed.
If there are not many MAC addresses to be distributed across an aggregation group, the distribution among the destination ports tends to become biased. To reduce such bias, use a distribution method that uses more MAC addresses.
If a server is connected to an aggregation group and a client is connected to a different port, it is recommended that either "src-mac" or "dst-src-mac" be used.
If the load balancing of frame forwarding is questioned, the traffic state of each port can be checked by using the "monitor traffic-bytes" or the "monitor traffic-counts" commands.
113/288
All Rights Reserved, Copyright (C) PFU LIMITED 2008
XG2000 series User's Guide distribution-parameter <0-3>
Specifies a parameter used in calculating of frame distribution method.
When this parameter is omitted, "0" is assumed.
Under certain circumstances, load balance bias may not be resolved, when the distribution method is changed. By changing the distribution parameter value, the bias can be minimized.
However, this value affects the distribution patterns only. Changing the value does not guarantee resolution of frame distribution bias. minimum-port <1-10>
Specifies the minimum number of ports in a link up state required to maintain the link up state of the aggregation group.
When the number of ports in a link up state within an aggregation group is less than the minimum number of ports specified, the aggregation group changes to a link down state.
When this parameter is omitted, 1 is assumed. port <1-20> <1-20> [ <1-20> ]
Assigns port numbers to an aggregation group. Separate each port number with a " " (space).
Specify two or more port numbers.
Command type

XG2000 series User's Guide
Note
Among the ports belonging to an aggregation group, the port with the smallest port number will be the master port.
Ports added to an aggregation group immediately after a link aggregation group is initially created will inherit the same settings as that of the master port. The values different from the master port are as follows:
− "link-pass-through" settings for each appended port will be cleared.
− The MAC address table entries for each appended port will be cleared.
− The values for "spanning-tree port-path-cost" will change in accordance with the number of member ports.
When changing the setting of an aggregation group already created, if the following conditions are met, the aggregation group will change temporarily to a link down state and then to link up again and the port setting becomes default.
− When the master port is deleted.
− When the master port is changed.
− When protocol or lacp-mode parameters are changed.
A port belonging to an uplink domain cannot be assigned to a link aggregation group.
Example
Set up a static link aggregation group with ports 1 and 2 as aggregation group number 1.
Then move to the interface edit mode of the aggregation group, and assign a VLAN ID of 2. xg(config)# link-aggregation agg-port 1 protocol none port 1 2 xg(config)# interface agg-port 1 xg(config-agg)# port-vlan-id vlan 2
Set up an LACP link aggregation group of LACP with ports 3, 4, and 5 as aggregation group number 2.

After eliminating the cause of the violation, clear the violation state with the "clear violation" command to return the port to usable state.
When port security is enabled, throughput decreases by about 10%, since the forwarding overhead increases. Also, receiving a frame that causes a security violation affects transmission from the port. Therefore, in an environment where security violations occur frequently, a decrease in the transmission rate should be anticipated.
Example
Set port security to switch port 3.
Then, when port 3 is in violation, check the port state using the "show interface" command.
After eliminating the cause of violation, make it usable again using the "clear violation" command. xg(config)# interface port 3 xg(config-if)# port-security violation shutdown xg(config-if)#exit xg(config)#exit
-
← When the port is in violation state. xg#show interface port 3

Command syntax ingress-bandwidth <40-10000> no ingress-bandwidth
Parameter
<40-10000>
Specifies the ingress rate limiting value in the range of 40 to 10000 Mbps. The value must be an integer divisible by 40.
For an aggregation group, the specified ingress rate limiting value applies to each port comprising the aggregation group. The total ingress rate limiting value for the aggregation group will be the specified ingress rate limiting value multiplied by the number of ports.
Command type
Configuration command
Default
10000
Message
% The set value is not step of 40.
Explanation
The specified ingress rate limiting value is not an integer divisible by 40.
Solution
Specify the ingress rate limiting value with an integer divisible by 40.
Note
For the specified ingress rate limiting value x, the actual ingress rate limiting value used is expressed in the approximation below.
Actual ingress rate limiting value = {integral part of (rate 256 / 10000)} 10000 / 256
Measurement of the ingress rate is done in increments of 100
µs. Therefore, when burst transfers are performed that exceed 100
µs, the actual permitted ingress rate will be smaller than the specified value.
Example
Set the ingress rate of port 3 to 5Gbps. xg(config)# interface port 3 xg(config-if)# ingress-bandwidth 5000

5.11.5 port-vlan-id
Function
The port-vlan-id command allows assigning a port to explicitly belong to a VLAN and configure the VLAN as a group of ports.
However, when a frame with VLAN tags is received, the VLAN tag information has precedent over the port VID.
This command sets the default port VID (PVID) of the switch port. Also, the command registers it as a VLAN member port
(without a tag).
Use the no form to return to the default value.
Prompt
xg(config-if)# or xg(config-agg)#
Command syntax port-vlan-id vlan <1-4094> no port-vlan-id
Parameter

[[Inserted string]]%1$: VID
[[Inserted string]]%2$: Port number
Solution
Create the VLAN first then reissue the command.
Note
When this command is issued, the port is registered as a member of the specified VLAN (having no tag). The frame having no tag is sent during egressing. To change the rule during egressing to “transfer tagged frames,” issue “vlan-member allowed vlan
<1-4094> egress-tagging”.
Example
Set the default PVID of switch ports 2 and assign it to “vlan-floor2”, VID=3.
Then, display the VLAN information using the “show vlan” command and make sure that VID 3 was registered with port 2 as a member (untagged frames during egressing). xg(config)# interface port 2 xg(config-if)# port-vlan-id vlan 3 xg(config-if)# exit xg(config)# exit xg# show vlan

Explanation
The specified the band width value is not an integer divisible by 100.
Solution
Sets a band width value with an integer divisible by 100.
% The total value exceeded 10000
Explanation
The sum of the bandwidth values of each output queue is exceeds 10Gbps.
Solution
Changes the bandwidth values so the total does not exceed 10Gbps.
Note
Residual bandwidth is assigned to each output queue without specified bandwidth. Enabling jumbo frames and the frame size established affects minimum bandwidth assignments across all output queues. The "The total value exceeded 10000" error message may be displayed despite the fact the total bandwidth assigned a given queue does not exceed 10Gbps.
Setting bandwidth 0 is same as no form, so the configuration is cleared.
Example
Sets 4Gbps for output queue "0" s. xg(config-if)# no qos bandwidth xg(config-if)# qos bandwidth 4000 output-priority 0

5.15 Statistics Commands
The device provides a wide variety of statistical displays.
Statistics can be displayed using the “monitor” command, which periodically updates the display information, or by using the
“show statistics” command which displays a snapshot.
The transmission byte statistics information does not include preambles (framing bytes).
Set the terminal screen size to 50 columns by 12 lines or more when issuing the “monitor” command.
If the terminal screen size is too small, the following message is displayed.
% terminal line is too small
or
% terminal width is too short
The number of statistics display lines vary depending upon the counter used.
If the line length exceeds the limit, the following unit is displayed at the right of the displayed value. The unit indicates a multiplier for the value displayed.
K: 1,000
M: 1,000,000

A.3 Message Format for Forwarding syslog
The logs output from the device can be forwarded to a syslog server. The device forwards logs in a message format that conforms to the RFC3164 The BSD Syslog Protocol.
The format the device uses to forward a syslog message to the syslog server is shown below.

MSG part
HostName
Tag
Content
The device appends the Priority value at the beginning of the log message then inserts the Device type between the Host name and the Function type before forwarding the message to the specified syslog server.
The Priority value is used to identify the severity and facility of a log message.
It is added according to the following rules.
Priority must have three, four, or five characters. It starts with an angle bracket "<", followed by a number, followed by an angle bracket ">". Example: <14>
The Priority value is calculated from the Facility code (Facility) and the Severity code (Severity). The Priority value consists of one, two, or three decimal integers.
The Priority value is calculated by first multiplying the Facility code by 8 and then adding the numerical value of the
Severity code.
The Facility code defined in the device is:
Facility code Type of Facility
1 random user-level messages
The Severity codes defined in the device are:
