Configuring the Revertive Timer
1:1 pseudowire path protection can be configured to operate in revertive mode. In revertive mode, the system
monitors the availability of the protected path at all times. After switchover to the protecting path, once the
protected path is operational and available without any alarms, the system waits for the duration of the user-
configured Wait to Restore (WTR) time and then, if the protected path remains operational and available, initiates
a revertive protection switch. A single WTR time is configured for all the pseudowire services in the system.
However, services with 1:1 path protection can be configured individually as revertive or non-revertive.
Note
Pseudowire services with 1:1 path protection that were configured using software versions prior to
T7.9 are non-revertive.
To set the WTR time for services with revertive 1:1 path protection:
1 Underneath the TDM PseudoWire Services table, click Timer Configuration. The TDM Service Revertive
Timer Configuration page opens.
Figure 309 TDM Service Revertive Timer Configuration Page
2 Enter the number, in seconds, for the WTR time. The default value is 10 seconds.
3 Click Apply, then Close.
