Media Interface Link Detection and Gateway Polling Configuration

To configure global media interface link detection and gateway polling:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type system and press Enter to access the system-level configuration elements.
```
ORACLE(configure)# system
```
Type redundancy and press Enter.
```
ORACLE(system)# redundancy
```
From here, you can configure gateway heartbeat parameters. To view all gateway heartbeat parameters, enter a ? at the system prompt.
gateway-heartbeat-interval—Enter the number of seconds between heartbeats for the media interface gateway. Heartbeats are sent at this interval as long as the media interface is viable. The default value is 0. The valid range is:
- Minimum—0
- Maximum—65535
gateway-heartbeat-retry—Enter the number of heartbeat retries (subsequent ARP requests) to send to the media interface gateway before it is considered unreachable. The default value is 0. The valid range is:
- Minimum—0
- Maximum—65535
gateway-heartbeat-timeout—Enter the heartbeat retry time-out value in seconds. The default value is 1. The valid range is:
- Minimum—0
- Maximum—65535
  
  This parameter sets the amount of time between Oracle® Enterprise Session Border Controller ARP requests to establish media interface gateway communication after a media interface gateway failure.
gateway-heartbeat-health—Enter the amount to subtract from the Oracle® Enterprise Session Border Controller’s health score if a media interface gateway heartbeat fails. If the value you set in the gateway time-out retry field is exceeded, this amount will be subtracted from the system’s overall health score. The default value is 0. The valid range is:
- Minimum—0
- Maximum—100
