Dell S4048T, Configuration Manual

Page: 587 / 1277

To view the failover group configuration, use the
show running-configuration po-failover-group
command.
Dell#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 65. 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.
Dell#show interface port-channel 2

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.
