I have a serious issue on my hands with a Nexus 3K switch. We just upgraded to 3.0(2)A8(11b) from 6.0.2.A8.10. So not a big jump. It was meant to be the first in a series of upgrades, but that is another matter.
All SVI's are showing Protocol Down, and the VPC Peerlink is down because it can't talk to IP address on the other side of the peer link.
The interfaces themselves for the peerlink are showing up, and the port channel for the peer link is up. all other VPC port channels are down. I can't ping the peer link IP address even from the local switch, so obviously nothing else can reach it either.
