ServiceChange Notification for Interface Status Change

Note For more details on the sbc interface-idcommand, see the Cisco IOS Integrated Session Border Controller Command Reference.

The ServiceChange H.248 notification is generated by any of the following events:

•Link up and link down.

For link up—MG Service Restoration event. The ServiceChangeMethod is Restart and the ServiceChangeReason is 900 (Service Restored).

For link down—MG Service Cancellation event. The ServiceChangeMethod is Forced and the ServiceChangeReason is 905 (Term taken Out Of Service).

•Interface shutdown or interface online insertion and removal (OIR).

The ServiceChange Notification for Interface Status Change feature has the following restrictions and conditions:

•It is only supported on EtherChannel (gigabit EtherChannel and fast EtherChannel) and on all Ethernet interfaces. EtherChannel may also be called port channel.

•The sbc interface-idcommand cannot be configured on VLAN subinterfaces or any subinterfaces.

•When a ServiceChange notification is sent, the termination ID is always reported wildcarded.

•It is generated well before the Media Timeout event, which has a 30 seconds default.

•If an interface configured with the sbc interface-idcommand goes down, the affected terminations are marked “Out Of Service.” If the DBE then receives an H.248 ADD or MODIFY request that moves one of these affected terminations “In-Service,” although the interface is marked “down,” the ADD or MODIFY request is not rejected. The request can move the termination state to “in-service,” even though the interface cannot accept any packets until it goes up. When the interface changes status to either up or down, the MG reports a service change with the affected termination IDs to the SBE.

Note The ServiceChange procedure is described in H.248.1v3 Annex F.
