Modifying a TDF Domain

This procedure describes how to use maintenance mode to modify a TDF domain. Options include modifying such parameters as TDF domain, mobile-interface, address filtering, AAA parameters, session characteristics, and access interfaces. You must first halt new sessions from being started and verify that there are no active sessions remaining.

To change a TDF domain for a group of subscribers that belong to that domain:

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

    This command displays the service-mode status for all the TDF domains. You can verify the status for the specific TDF domain and take action accordingly.

    The service mode for the TDF domain shows Maintenance – Active Phase if all the sessions using this TDF domain are cleared. The service mode for the TDF domain shows Maintenance - In Phase if some sessions are actively using this TDF domain.

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

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

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

    The command output displays the configuration changes you made to the TDF domain.

  9. Return the gateway to operational state.

Although maintenance mode does not explicitly include AAA options, certain AAA changes require you to place affected TDF domains in maintenance mode first. These changes include changing an AAA profile name and changing authorization or accounting elements. If you attempt to make AAA changes that affect a TDF domain that is not in maintenance mode, you are prompted to place the appropriate TDF domain into maintenance mode before proceeding with AAA profile name or element changes.
