The difference between the hold-timeout and the timeout parameters is as follows:
During the hold-timeout, the vPC secondary device does not take any action based on any keepalive messages received, which prevents the system taking action when the keepalive might be received just temporarily, such as if a supervisor fails a few seconds after the peer link goes down
During the timeout, the vPC secondary device takes action to become the vPC primary device if no keepalive message is received by the end of the configured interval.
keepalive hold-timeout : ----------------------------- * starts when vpc peer-link goes down. * during this time period, peer keepalive messages from vpc peer are ignored. * this is to give the links/vpc peer device time to come back up before any action is taken.
The idea is to give the system some time to recover, before the vpc secondary device takes any action.
keepalive timeout : ------------------------------ * starts at the end of the hold-timeout interval. * during this time period, the device waits for the peer-keepalive messages. * If peer-keepalive messages reveiced from the vpc peer, the secondary switch suspends it's vpc member ports and vlans. * If no peer-keepalive messages received from the vpc peer, the secondary switch now assumes the vpc primary role.
