(Optional) after the ring Guard timer is
configured, the failed node does not
process APS packets during a period. In a
bigger ring network, if the failed node
recovers from a fault immediately, it may
receive the fault notification sent by the
neighbor node on the protection ring.
Therefore, the node is in Down status
again. You can configure the ring Guard
timer to solve this problem.
(Optional) configure the ring WTR timer.
wtr-
In revertive mode, when the working line
recovers from a fault, traffic is not
switched to the working line unless the
WTR timer times out.
(Optional) configure the ring Hold-off
timer. After the Hold-off timer is
configured, when the working line fails,
the system will delay processing the
fault. It means that traffic is delayed to be
switched to the protection line. This
helps prevent frequent switching caused
by working line vibration.
If the ring Hold-off timer value is too
great, it may influence 50ms
switching performance. Therefore,
we recommend configuring the ring
Hold-off timer value to 0.
