Modifying the TDF Interface of a TDF Domain

This procedure describes how to use maintenance mode to modify attributes of the TDF interface for a TDF domain. You must first halt new sessions from being started and verify that no active sessions remain.

To configure the mobile interface of a TDF domain:

  1. From configuration mode, activate maintenance mode for the TDF domain using the mobile interface to be modified.
  2. Verify that the TDF domain of this mobile interface is in maintenance mode.

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

    You cannot make and commit changes to a mobile interface unless the TDF domain to which it is attached is in maintenance mode.

  3. Verify that no subscribers are active on the TDF domain.
  4. (Optional) Terminate sessions that are using an address pool using the clear command.
  5. When the subscriber count is zero and all sessions have ended, make and commit changes to the TDF domain interface in active maintenance mode.
    Note:

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

  6. Modify the interface.
  7. Exit maintenance mode and commit the changes.
  8. Verify that changes were properly committed.
  9. Return the gateway to operational state.
