Requirements for vPC keepalive.

[Kevin Dorrell]

I know that if the vPC keepalive link fails, vPC is unaffected as long as the vPC peer-link is still up.  Effectively, the keepalive passes over the peer-link for the duration of the failure.

I have a slightly more complicated  requirement: I need to change the management addresses of the two vPC peers.  Will the vPC itself will fail during the change?  I am guessing that in the situation where the keepalive link fails, the keepalive traffic passes over the peer-link but still uses the management addresses.  If I want to change those addresses, am I going to have to book a maintenance slot?

Hi;

Yes you need a maintenance window for changing the peer-keepalive IP Address.
