Path Protection
Allows you to define the notification frequency of the path state as well as the restoration actions once the working path is repaired or restored. The protection mode defines whether or not the traffic is switched back from protection path to the working path. There are two modes of operation:
− Revertive mode
The traffic is automatically switched back from the protection path to the working path after the expiration of the Wait-to-Restore (WTR) timer.
− Non Revertive mode
The traffic is not automatically restored to the working path, even if the working path is repaired. Thus, administration form of intervention, i.e. a “Manual Switch” is needed to invoke restoration action if required.
This mode is employed if the administrator wants to gain assurances about the integrity of the path before switching path or if it is acceptable to continue operation without the (protection) path being protected.
