Configuring the Service State of a VPG or a Virtual Interface

You can set the service state of a VPG or a virtual interface. You can set the service state to in-service, or you can perform a forced or graceful shutdown of the VPG or virtual interface.

Configuring the service state of a virtual interface is useful when you do not want to shut down the entire VPG.

Configuring the Service State of a VPG

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




service-state (in-service
| out-of-service-forced | out-of-service-graceful);

To cause the VPG to be operational and available for traffic, set the service state to in-service. When the VPG is in service, it attempts to connect to the PGC and accepts all PGCP commands from the PGC.

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

Forced—The VPG immediately removes all gates and disconnects from the PGC. The packet gateway does not attempt to establish a new connection.
Graceful—The VPG 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 VPG accepts only subtract commands from the PGC.

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:




service-state (in-service
| out-of-service-forced | out-of-service-graceful);

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.
