Examples of Configuring and Viewing LAGs
In the following example, LAGs 1 and 2 have been placed into to the same failover group.
R2#config
R2(conf)#port-channel failover-group
R2(conf-po-failover-grp)#group 1 port-channel 1 port-channel 2
To view the failover group configuration, use the show running-configuration po-failover-group
command.
R2#show running-config po-failover-group
!
port-channel failover-group
group 1 port-channel 1 port-channel 2
As shown in the following illustration, LAGs 1 and 2 are members of a failover group. LAG 1 fails and LAG 2 is
brought down after the failure. This effect is logged by Message 1, in which a console message declares both
LAGs down at the same time.
Figure 61. Configuring Shared LAG State Tracking
The following are shared LAG state tracking console messages:
•
2d1h45m: %SYSTEM-P:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Po 1
•
2d1h45m: %SYSTEM-P:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Po 2
To view the status of a failover group member, use the show interface port-channel command.
R2#show interface port-channel 2
