description

Provide a brief description of the realm-config configuration element

• Default: 0.0.0.0

An IPV6 address is valid for this parameter.

network-interface

Enter the network interface through which this realm can be reached. Entries in this parameter take the form: <network-interface-ID>:<subport>.<ip_version>.

Note:

Only one network interface can be assigned to a single realm-config object.

Enable or disable media being steered through the Oracle Communications Session Border Controller when the communicating endpoints are located in the same realm

• Default: disabled
• Values: enabled | disabled

mm-in-network

Enable or disable media being steered through the Oracle Communications Session Border Controller when the communicating endpoints are located in different realms within the same network (on the same network-interface). If this field is set to enabled, the Oracle Communications Session Border Controller will steer all media traveling between two endpoints located in different realms, but within the same network. If this field is set to disabled, then each endpoint will send its media directly to the other endpoint located in a different realm, but within the same network.

• Default: enabled
• Values: enabled | disabled

If this field is set to disabled, the media and signaling will pass through both Oracle Communications Session Border Controllers. If this field is set to enabled, the media is directed directly between the endpoints of a call.

• Default: disable
• rbt
• asymmetric-preconditions

• Range: 1 - 95%

steering-pool-alarm-monitoring-time

Operates in conjunction with the steering-pool-lower-threshold, and specifies in minutes the duration for which the system considers an alarm condition triggered by the steering-pool-threshold as still in effect. After the system triggers this alarm, it uses this window as the amount of time steering pool port usage must be below the steering-pool-lower-threshold before the system can issue a new steering-pool-threshold alarm. This logic prevents the system from issuing multiple alarms for what you consider the same issue.
