The Link Monitor Configuration table is used to configure information for the following:

  • CAC/IPSEC. Link is monitored for CAC/IPSEC profile.
  • Backup Default Route. When the SBC 1000/2000 or SBC SWe Edge is configured to for Destination Resiliency (Backup Default Route), the Link Monitor checks for problems on the default route to the ISP. The SBC recognizes when the Internet destination is not reachable from a given (preferred) ISP; all subsequent calls are routed (via backup default route) to the secondary ISP to reach the intended Internet destination. For details on configuring a Backup Default Route, refer to Best Practice - Configure Destination Path Resiliency through Independent Internet Connections.
Note

CAC/IPSEC is only applicable to the SBC 1000/2000.

The Backup Default Route feature is applicable to the SBC 1000/2000 and SBC SWe Edge.

For SBC SWe Edge, Monitor Type is a read-only option and is always set to Backup Default Route.
