VPC consistency check error

[sushilverma05]

I have 2 Nexus 5548 switches. I'm facing issues on VPC status down and consistency check not performed.

Below is the output.

Hi Sushil

It seems your vpc peering is perfect but there is some problem with the port channel configuration (po216). It would be nice to share the configuration. The port configuration must be same on both switches part for physcial interface. 

sh run interfac po216 

sh run inter ethernet "physical port number "

see port configuration on following example

sw01# sh running-config inter po 12

!Command: show running-config interface port-channel12
!Time: Mon Oct  6 12:19:53 2014

version 5.2(1)N1(7)

interface port-channel12
  description data
  switchport access vlan 2106
  spanning-tree port type edge
  vpc 12

sw02# sh run inter po 12

!Command: show running-config interface port-channel12
!Time: Mon Oct  6 12:20:46 2014

version 5.2(1)N1(7)

interface port-channel12
  description data
  switchport access vlan 2106
  spanning-tree port type edge
  vpc 12

Hi Syed,

see below port-channel config and interface config. both are identical.

N5k-SW1
interface port-channel216
  switchport mode trunk
  spanning-tree port type edge trunk
  vpc 216

interface Ethernet106/1/16
  description SWIGEDPM200
  switchport mode trunk
  spanning-tree port type edge trunk
  channel-group 216 mode active

N5K-SW2
interface port-channel216
  switchport mode trunk
  spanning-tree port type edge trunk
  vpc 216

interface Ethernet107/1/16
  description SWIGEDPM200
  switchport mode trunk
  spanning-tree port type edge trunk
  channel-group 216 mode active

May be the output of following would help 

sh vpc consistency-parameters vpc 216 

sh vpc consistency-parameters global

and also the ouput of sh inter po xx from the far end switch ? and if its server than please double check the lacp config are correct etc.
