Media Interface Link Detection and Gateway Polling

You can use media interface link detection and gateway polling globally on the Oracle® Enterprise Session Border Controller, or you can override those global parameters on a per-network-interface basis.

Use the Oracle® Enterprise Session Border Controller HA node (redundancy) configuration to establish global parameters. When configured globally, they will appear like this in the ACLI:
```
gateway-heartbeat-interval     0
gateway-heartbeat-retry        0
gateway-heartbeat-timeout      1
gateway-heartbeat-health       0
```

Use the network interface’s gateway heartbeat configuration to override global parameters on a per-network-interface basis. When configured for the network interface, these parameters will appear like this in the ACLI:

gw-heartbeat
                state                          enabled
                heartbeat                      0
                retry-count                    0
                retry-timeout                  1
                health-score                   0
