Configuration Of A Lag; Creating A Link Aggregation Group (Lag) - Dell PowerConnect B-RX Configuration Manual

Configuration of a LAG

The following configuration procedures are used to configure a LAG. Depending upon whether you
are configuring a static, dynamic or keep-alive LAG, the configuration procedures may or may not
apply as described:

Creating a Link Aggregation Group (LAG)

Before setting-up ports or configuring any other aspects of a LAG, you must create it as shown in
the following.
BigIron RX(config)# lag blue static
BigIron RX(config-lag-blue)#
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 .
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.
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 device. 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> ]

Creating a Link Aggregation Group – Required for all static, dynamic or keep alive LAGs.
Adding Ports to a LAG – Required for all static, dynamic, or keep alive LAGs. A keep alive LAG
contains only one port with static and dynamic LAGs can have 2 to 8 ports.
Configuring the Primary Port for a LAG – Required for all static and dynamic LAGs. Since a keep
alive LAG contains only one port, it is unnecessary to configure this parameter.
Specifying the Trunk Threshold for a Trunk Group – Optional for static and dynamic LAGs. Since
a keep alive LAG contains only one port, it is unnecessary to configure this parameter.
Configuring LACP Port Priority – Optional for dynamic and keep alive LAGs. Because static LAGs
do not support LACP, it is unnecessary to configure this parameter.
Configuring an LACP Timeout – Optional for dynamic and keep alive LAGs. Because static LAGs
do not support LACP, it is unnecessary to configure this parameter.
