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 62. Configuring Shared LAG State Tracking
The following are shared LAG state tracking console messages:
2d1h45m: %RPM0-P:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Po 1
2d1h45m: %RPM0-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.
NOTE:
The set of console messages shown above appear only if you configure shared LAG state tracking on that router
(you can configure the feature on one or both sides of a link). For example, as previously shown, if you configured shared
LAG state tracking on R2 only, no messages appear on R4 regarding the state of LAGs in a failover group.
Important Points about Shared LAG State Tracking
The following is more information about shared LAG state tracking.
This feature is available for static and dynamic LAGs.
Only a LAG can be a member of a failover group.
You can configure shared LAG state tracking on one side of a link or on both sides.
If a LAG that is part of a failover group is deleted, the failover group is deleted.
If a LAG moves to the Down state due to this feature, its members may still be in the Up state.
