Per-VLAN Consistency Check

Some Type-1 consistency checks are performed on a per-VLAN basis when spanning tree is enabled or
disabled on a VLAN. VLANs that do not pass the consistency check are brought down on both the primary
and secondary switches while other VLANs are not affected.

vPC Auto-Recovery

The vPC auto-recovery feature re-enables vPC links in the following scenarios:
When both vPC peer switches reload and only one switch reboots, auto-recovery allows that switch to assume
the role of the primary switch and the vPC links will be allowed to come up after a predetermined period of
time. The reload delay period in this scenario can range from 240 to 3600 seconds.
When vPCs are disabled on a secondary vPC switch due to a peer-link failure and then the primary vPC switch
fails or is unable to forward traffic, the secondary switch reenables the vPCs. In this scenario, the vPC waits
for three consecutive keepalive failures to recover the vPC links.

vPC Peer Links

A vPC peer link is the link that is used to synchronize the states between the vPC peer devices.
Note
You must configure the peer-keepalive link before you configure the vPC peer link or the peer link will not
come up.
