The signaling group allows for administration of a “Cluster ID”, if the Clustered field is set to ‘y’. Cluster ID is a new field that allows for association of a Session Manager cluster with a signaling group. The field “Far-end Node Name” will be replaced with field “Cluster ID” up on setting “Clustered” to ‘y’. The “Peer Server” field will be read only and will be set to SM. The Enable Layer 3 Test field will be set to y and will be read only. The clustering functionality works only with Avaya Aura® Session Manager.

Administration of a Session Manager cluster on a Signaling Group form allows the signaling group to point to all Session Managers in the cluster. In this example, see the figure in the Cluster Session Manager section and figure in the Signaling group section, the signaling group is pointing to primary and secondary Session Managers.

The SIP signaling group remains in service if at least one Session Manager is reachable from Communication Manager. The signaling group is out of service if all the Session Managers in the cluster are not reachable.
