Re: OT: Nexus deployment with 802.3ad LACP team

Hi,

The config looks okay. I'd add this, just to make sure the right vrf (if
you're using any).

vpc domain 1
  peer-keepalive destination 10.0.0.1 source 10.10.0.2 vrf vpc-keepalive

Are you issueing show vpc status command from base system i.e. mgmt vdc or
one of the vdc which has peering with another one on a different box?

use switchto vdc <vdcName> command and then check the vpc status.
