MLAG interface.

Step 1: Check the Peer Link
1.
Check if the MLAG is enabled globally.
2.
Check if keep-alives are enabled in the VPC domain.
3.
Check if the peer link is a LAG.
4.
Check the status of the ports of the peer link.
5.
If the ports links are up, check the status of the LAG.
If the LAG is up, skip the following step.
6.
If the LAG is down, check if the following parameters are identical on the peer link:
•
Port-channel mode
•
Link speed
•
Duplex mode
•
MTU
•
Bandwidth
•
VLAN configuration
•
LACP parameters:
-
Actor parameters
-
Admin key
-
Collector max-delay
-
Partner parameters
