Revertive Mode Overview


By default, APS is nonrevertive, which means that if the protect circuit becomes active, traffic is not switched back to the working circuit unless the protect circuit fails or you manually configure a switch to the working circuit. In revertive mode, traffic is automatically switched back to the working circuit.

You should configure the ADM and routers consistently with regard to revertive or nonrevertive mode.

If you are using nonrevertive APS, you can use the request working statement to switch the circuit manually to being the working circuit or to override the revert timer (configured with the revert-time statement).
