Syntax: [no] lag <lag-name> static | dynamic | keep-alive
Refer to
conventions.
The static option specifies that the LAG with the name specified by the <lag-name> variable will be
configured as a static LAG. The static LAG configuration is much the same as the Trunk feature
available in releases prior to 02.6.00.
The dynamic option specifies that the LAG with the name specified by the <lag-name> variable will
be configured as a dynamic LAG. The dynamic LAG configuration is much the same as the LACP
feature available in releases prior to 02.6.00.
The keep-alive option specifies that the LAG with the name specified by the <lag-name> variable
will be configured as a keep-alive LAG. The keep-alive LAG configuration is a new configuration
option to configure a LAG for use in keep alive applications similar to the UDLD feature.
Adding ports to a LAG
A static or dynamic LAG can consist of from 2 to 20 ports of the same type and speed that are on
any interface module within the BigIron RX chassis. A keep alive LAG consists of only one port.
To configure the static LAG named "blue" with two ports, use the following command.
BigIron RX(config)# lag blue static
BigIron RX(config-lag-blue)# ports ethernet 3/1 ethernet 7/2
Syntax: [no] ports ethernet <slot/port> [ to <slot/port> ] [ ethernet <slot/port> ]
The ports added to a LAG are ethernet as specified for the slot/port where they reside. The ports
can be added to the LAG sequentially as shown in the following example.
BigIron RX(config-lag-blue)# ports ethernet 3/1 ethernet 7/2 ethernet 4/3 ethernet
3/
A range of ports from a single interface module can be specified. In the following example, Ethernet
ports 1, 2, 3 and 4 on the interface module in slot 3 are configured in a single LAG.
BigIron RX(config-lag-blue)# ports ethernet 3/1 to 3/4
Additionally, you can mix a range of ports from one interface module with individual ports from
other interface modules to form a LAG as shown in the following.
BigIron RX(config-lag-blue)# ports ethernet 3/1 to 3/4 ethernet 10/2
NOTE
Beginning with release 02.6.00, a port can be added to or deleted from a LAG only if the LAG is not
currently deployed.
Configuring the primary port for a LAG
In previous versions of the Multi-Service IronWare software, the lowest number port was assigned
as the primary port in a trunk or LACP configuration. In version 02.6.00 and later, the primary port
must be explicitly assigned. using the primary port command.
To designate the primary port for the static LAG "blue", use the following command.
BigIron RX(config)# lag blue static
BigIron RX(config-lag-blue)# primary port 3/2
