show mgc

Last Updated : Jun 04, 2021 |

Displays the currently active media gateway controller state, setup parameters and the gateway mode.

This command will also display the H.248 Link Encryption technique that has been registered with Communication Manager. The technique can be TLS, PTLS or none.

Additionally, when the gateway mode is set to Edge, this command will also display the status of MGSBC management link between the Edge Gateway and Avaya SBC.

Note:

The media gateway configured in Edge mode will only use TLS version 1.2 for the following links:

  • H.248 link between the Edge Gateway and Avaya SBC

  • MGSBC management link between the Edge Gateway and Avaya SBC
