Verifying the Media Gateway Controller List

Purpose

Verify that the Media Gateway Controller (MGC) list is correctly configured and that the MGCs are reachable over the network.

Action

From the operational mode in the CLI, enter show tgm fpc slot-number media-gateway-controller.

Sample Output

Media gateway controller(s): 173.26.232.77
                             10.10.10.30
                             10.10.10.40

Meaning

The output shows the configured MGC list. Verify the following:

• The IP addresses and the order of the IP addresses in the MGC list are correct. The first MGC on the list is the primary MGC. The TGM550 searches for the primary MGC first. If it cannot connect to the primary MGC or loses its connection to the primary MGC, it attempts to connect to the next MGC in the list, and so on.
• Use the JUNOS CLI ping command or the J-Web ping host tool (Troubleshoot>Ping Host) to verify that the configured MGCs can be reached over the network.
