Seems that your change didn't cover scenario 1.
The goal is to confirm when one ToR toggles mux direction, the other ToR will be in sync eventually even without icmp heartbeats.
Scenario 1 link flap after boot up.
One side ToR toggles mux, and the other side is able to sync up in short amount of time.
