This read-only INTEGER reports the number of seconds remaining before this port's Wait While timer expires, which governs how long the Mux state machine waits before attaching the port. An admin can use it to see how long a newly-selected port will remain in the waiting state before actually joining the aggregate and starting to forward trunk traffic. For example, watching this timer count down to zero on a newly cabled port shows exactly when it will transition from waiting to attached in the aggregate.
