Meaning
Use the show services pgcp active-configuration command to see your configuration and to display the current status of your virtual interfaces, virtual BGF (Packet gateway configuration), and services interfaces.
In addition, make sure that:
Purpose
Verify that gates are running on bgf-1.
Action
user@sp-bgf-router> show services pgcp
gates gateway bgf-1Packet gateway configuration: Name : bgf—1 IP address : 172.16.10.1 Port : 2944 Status : In-Service (Registered) Gate information: Gate id: 4295033088 Gate state: active Action: forward Service set id: 1 Media card: sp-1/2/0 Media handler: bgf1-svc-set Termination-id-string: ip/4/vif-0/2 Gate id: 4295033089 Gate state: active Action: forward Service set id: 1 Media card: sp-1/2/0 Media handler: bgf1-svc-set Termination-id-string: ip/4/vif-0/3
Meaning
The show services pgcp gates command lists the gates on the virtual BGF. It shows whether gates are active, disabled, or closed. It also shows the current action being performed on the gate—forward, add, or drop.
Purpose
Verify the terminations on bgf-1.
Action
user@sp-bgf-router> show services pgcp

Meaning
The show services pgcp terminations command lists the terminations on the virtual BGF. It shows whether the gates within a termination are active, disabled, or closed. You can use the termination names (termination IDs) to troubleshoot problems with voice calls.
Purpose
Verify the PGCP flows.

Meaning
The show services pgcp terminations gateway bgf-name h248 command presents the H.248 parameters as they have been set through H.248 requests and commands from the gateway controller. Comparing this output with the expected H.248 requests reveals whether there was a problem with the requests and commands that the gateway controller sent to the virtual BGF.
