Hello,
two nexus's 3k in VPC configuration with dedicated keepalive link.
If - for any disruption - the keepalive link goes temporary down, even when it returns UP (*) the only way to restore the correct functioning of the VPC is to ... restart one of the two NEXUS's.
And this creates an additional outage.
Does this seem normal to you, or is there something wrong with my config?
(*) UP means:
Peer status: peer adjacency formed ok
vPC keep-alive status: peer is alive
Configuration consistency status: success
Per-vlan consistency status: success
Type-2 consistency status: success
vPC role: primary, operational secondary
