Configuring a LAG
5
When the LACP forwarding is enabled on the primary port of the static LAG, the LACP BPDU
forwarding is enabled on all ports of the LAG when the LAG is deployed. When the static LAG is
undeployed the BPDU forwarding state is retained.
NOTE
LACP BPDU forwarding is not supported for any port of dynamic or keep alive LAGs.
• If LACP BPDU forwarding is enabled on the primary and secondary ports, the static LAG
deployment will be successful and LACP BPDU forwarding will be enabled on the LAG ports.
• If LACP BPDU forwarding is enabled on the primary port and disabled on the secondary ports,
the static LAG deployment will be successful and LACP BPDU forwarding will be enabled on the
LAG ports.
• If LACP BPDU forwarding is disabled on the primary and secondary ports, the static LAG
deployment will be successful and LACP BPDU forwarding will be disabled on the LAG ports.
Creating a keepalive LAG
To create a keep-alive LAG, enter the following.
Brocade(config)# lag lag1 keep-alive
Syntax: [no] lag name keep-alive
The keep-alive option specifies that the LAG with the name specified by the lag-name variable will
be configured a keep-alive LAG. The keep-alive LAG option allows you to configure a LAG for use in
keep alive applications similar to the UDLD feature.
Adding Ports to a LAG or Deleting Ports from a LAG
A static or dynamic LAG can consist of from 2 to 32 ports of the same type and speed that are on
any interface module within the Brocade chassis. A keep alive LAG consists of only one port.
To configure the static LAG named “blue” with two ports, use the following command:
Brocade(config)# lag blue static
Brocade(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 can be of type 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:
Brocade(config-lag-blue)# ports ethernet 3/1 ethernet 7/2 ethernet 4/3 ethernet
3/4
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:
Brocade(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:
Brocade(config-lag-blue)# ports ethernet 3/1 to 3/4 ethernet 10/2
Using the no option allows you to remove ports from a LAG. For example, you can remove port 3/4
from the LAG created above, as shown in the following:
Brocade(config-lag-blue)# no ports ethernet 3/4
