Configuring the Service State of a Virtual Interface

To set the service state of a virtual interface, enter the set service-state statement at the [edit services pgcp gateway gateway-name virtual-interface] hierarchy level:

To cause the virtual interface to be operational and available for traffic, set the service state to in-service. When the virtual interface is in service, it is connected to the physical interface and accepts all voice calls.

There are two ways to shut down the virtual interface—forced or graceful:

• Forced—The virtual interface immediately removes all calls and disconnects from the physical interface. The virtual interface does not attempt to establish a new connection.
• Graceful—The virtual interface goes out of service by entering a draining mode and waiting for all terminations to be subtracted before going out of service. During the draining, the virtual interface accepts only subtract commands from the PGC.
