User Guidelines
A VPC domain ID must be configured for this command to display the VPC
status.
Only the Primary switch maintains the member status of the Secondary
switch. The Secondary switch does not maintain or show the status of the
Primary switch peer members.
A VPC instance may show as enabled even if all of the port-channels that are
members of the VPC are disabled or all of the links in the port channels are
disabled. A VPC will show as disabled if peer-link (or DCPDP) connectivity is
lost.
The Keepalive admin status field shows the status of the peer-link protocol.
The VPC operational status shows the overall MLAG status.
The Peer detection admin status field shows the status of the DCPDP
protocol.
