If the switch goes into ring protection state due to a signal failure, after the
failure condition is cleared, the RPL owner will start the wait-to-restore
timer and wait until it expires to verify that the ring has stabilized before
blocking the RPL and returning to the Idle (normal operating) state.

•
Two steps are required to make a ring operating in non-revertive mode
return to Idle state from forced switch or manual switch state:
1.
Issue an erps clear command to remove the forced switch command
on the node where a local forced switch command is active.
2.
Issue an erps clear command on the RPL owner node to trigger the
reversion.
