Hi,
I have got two pairs of NEXUS switches 5k and 2k
The two 5 k are connected through 4 connections (port-channel) but it doesn't seems to work??
The idea is to setup a server with a double path connected to n2k -> 5k and create a VPC between the two differents switches on access mode
N11-BKP# show port-channel summary

I don't have a clue of what is happening
Thanks

Hi,
You do not have domain id in your config:
example:
switch(config)# vpc domain 5
have a look at this doc for more info:

Hi,
No I do have a domain 1 (on all of my switches) but I found the answer actually on the links between the two nexus
the vpc peer-link was missing
vpc domain 1
role priority 1
peer-keepalive destination 192.168.254.208
peer-gateway
