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

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.
