Deleting a TDF Interface

This procedure describes how to use maintenance mode to delete a TDF interface. You must first halt new sessions from being started and verify that no active sessions are remaining.

You can use maintenance mode to remove any of the TDF interfaces.

You can also enter maintenance mode to delete control and data portions of these interface configurations.

  1. From configuration mode, activate maintenance mode for a gateway.
  2. Verify that the TDF gateway is in maintenance mode.

    From the gateway hierarchy, the service mode for the gateway shows Maintenance – Active Phase if all the sessions using this pool are cleared. The service mode for the gateway shows Maintenance – In Phase if some sessions are actively using this pool. The service mode for the gateway shows Maintenance – Out Phase if maintenance mode is not configured (that is, the gateway is in operational mode).

  3. Verify that no subscribers are active on this gateway.
  4. (Optional) Terminate sessions that are using the gateway and clear CDRs using the following clear command.
  5. When the subscriber count is zero, and all sessions have ended, delete the TDF interface in active maintenance mode.

    These modifications must be made in active maintenance mode or they fail.

  6. Delete the TDF interface.
  7. Exit maintenance mode and commit the changes.
  8. Verify that changes were properly committed.
