What is your config look like :

example :

slot 100
  provision model N2K-C2232P

fex 100
  pinning max-links 1
  description "fex-100"

interface e1/1 - 2
channel-group 100

interface po100
switchport mode fex-fabric
fex associate 100

check : after power on FEX :

show fex

fex 104
pinning max-links 1
description "FEX0104"

interface Ethernet1/22
description to fex104
switchport mode fex-fabric
fex associate 104
channel-group 104

interface port-channel104
switchport mode fex-fabric
no lacp suspend-individual
fex associate 104
vpc 104

On the vpc-peer device ，the n2k state is online

[balaji.bandi · Accepted solution]

the config should match both the sides

show post - show fex 104 details from both the switches ?

also check the cables.

We reload the N2K and then the trouble disappeared。

Thanks for you help
