vPC Peer Reload Issue

[philip.ilori1]

We have 2 nexus switches in vPC for DC Aggregation. A reload to primary vPC causes a 2 minutes 17 seconds outage in the Data center. The reload was a very unusual occurrence since the DC is power redundant. However, we are proactively finding a solution to this problem. Its a 7009 platform with F3 Line cards.

Hi, what does the show version says on the " Last reset" section  of the nexus that reloaded?

After much testing and TAC involvement, we found that the 3 minutes downtime was from BGP on the Core switch. By Adjusting the bgp timer to 10 seconds, we were able to reduce our downtime.
