Hi Everyone.
I'm trying to establish vPC between two nexus 5596 switch. Peer status is down however keep-alive status is up.. Physical interface is up on both the switches. Below is the configuration output:
Nexus5K-1(config-if)# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
vPC domain id : 10
Peer status : peer link is down
vPC keep-alive status : peer is alive
Configuration consistency status : failed
Per-vlan consistency status : success
Configuration inconsistency reason: Consistency Check Not Performed
Type-2 inconsistency reason : Consistency Check Not Performed
vPC role : none established
Number of vPCs configured : 1
Peer Gateway : Disabled
Dual-active excluded VLANs : -
Graceful Consistency Check : Enabled
Auto-recovery status : Disabled
vPC Peer-link status
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
1 Po10 up -
==================================================
Nexus5K-1(config-if)# show run | sec vpc
feature vpc
vpc domain 10
role priority 2000
system-priority 4000
peer-keepalive destination 172.28.1.100 source 172.28.1.120 vrf default
vpc peer-link
vpc 20
Nexus5K-1(config-if)# show run int port 10
interface port-channel10
switchport mode trunk
spanning-tree port type network
speed 10000
vpc peer-link
!!!
Nexus5K-1(config-if)# show int Eth1/24
Ethernet1/24 is up
Dedicated Interface
Belongs to Po10
!!!!
Nexus5K-1(config-if)# show int Eth1/25
Ethernet1/25 is up
Dedicated Interface
Belongs to Po10
Any Guidance is much appreciated... Thanks in advance

Hi Vivek,
Hmmm, that's strange. Would you mind posting the output of the following commands from both vPC peers please? I know you've posted some of them already but it would be helpful to have the most recent outputs, and to have them from both switches at the same time. As for the following commands, please copy&paste them exactly into your switches as shown below without any own modifications, then please post the complete outputs here. Thanks!
terminal length 0 show run vpc show vpc show run po10 membership show port-channel summary
show interface po10
show interface e1/24
show interface e1/25
terminal no length
Best regards,
Peter

Thanks Peter.
Issue is resolved now. Problem was I brought up all the physical connections up and then configured the keepalive link and followed by peer. However we need to ensure that the peer links should be admin down till we bring up the keep-alive link.
Thanks,
Vivek
