Configuring APS for Link Failures
Configuring APS for Link Failures
Automatic Protection Switching (APS) configures how MASTERseries responds to link failures. For
example, you can configure MASTERseries to switch to an alternate link when another link fails (red,
blue/AIS or yellow alarm). If a link fails or degrades below the user-defined thresholds, APS can
automatically re-route and/or vary link or channel parameters. When the failed link has been restored
to service, the APS feature can be configured to automatically return to the original configuration or
remain on the switched configuration.
If APS is set for a link on the master module and the master module fails, then a master toggle will take
priority over APS. The new master will take over and continue to run the current configuration.
To access the Auto Protection Switch window, select
the desired card in the Tree View, right-click to display
the context menu, and select Auto Protection Switch.
For each link, select the configuration you want to use
for the APS. In the event of a link failure, the system
performs an automatic protection switch to the specified
configuration.
To configure APS:
1. Select the desired card in the Tree View, right-click to display the context menu, and select
Auto Protection Switch.
2. The Card: Auto Protection Switch window displays.
3. The links are displayed in the left-hand column. For each link, you can select a configuration
to switch to in the event of a failure, or select NO APS (default).
Do not select the currently running configuration. The system will not perform APS if you
select the same configuration for APS as your running configuration.
