Config sync on Nexus 5K

[kthned]

Hi

I have two nexus in vpc domain 1. VPC is running fine without problem.

When I configured the config sync on both nexus, switch profile status shows peer unreachable. Wondering why peers are unreachable in ONLY conf-sync case, when both vpc and switch profile configs are configured with mgmt IP address. configuration below. Am I missing any thing... does anyone has any comment ? Thanks

Configuration is attached !

In nexus 5K switch profile configuration is synced only through Mgmt 0 interface. Make sure you configure the Mgmt interface on both switches and their reachability. Configure the Mgmt 0 ip address for vpc domain peer and switch-profile sync peer and everything should work ok.

Hi Venkata

I can ping the remote Mgmt IPs using ping nexus_ip vrp management. vPC is working fine but it is switch-profile which seems to have a problem. Could you expand a bit on this

Got it solved, actually cfs was culprit . See the solution here
