Tunnel Health Checks
Starting in software version 5.3, there are tunnel health checks. The reachability of IP destinations is checked and, if the destinations are not reachable, packets will not be sent or will stop being sent.
The tunnel health check on the GigaSMART card defines destinations as follows:
| IP destinations used for sending packets from a single IP interface with tool port to a single IP destination |
| tunnel endpoints used for load balancing from a single IP interface with tool port to multiple IP destinations |
An SNMP notification can be sent when the status of a IP destination or tunnel endpoint changes, either from Up to Down or from Down to Up.
Note: Tunnel Health-check is not supported for GMIP tunnel.
To enable the SNMP notification, refer to Enable or Disable Events for SNMP Notifications..
