We have two Nexus 7010 switches running a vPC domain between the two switches. On one of the 7010B, the peer keep alive (from the mgmt VRF) is connected to a 3560B *and* that 3560B also has a data connection back to the same 7010B. Everything is fine with that setup.
Our second 7010A, the peer keep alive link is also connected to a coresponding 3560A switch. However, that 3560A switch is not connected to 7010A.
I want to move the uplink from the 3560A from where it is to the 7010A which will break the keep alive. However, I will not be breaking the vPC peer link as it is a pair of 10G connections between the two 7010 switches.
I have read that the vPC won't come up unless the peer keep alive is present, but it wasn't clear about taking down the keep alive link momentarily. Moving the cable would be quick, but I know the mac table will need to update since 7010B switch will now see the keep alive across it's peer link instead of some other direction.
Can I take the peer keep alive link down providing the peer link stays up?
We are running kickstart and system version 5.0(3).
