Change the MTU of an OAM Interface Using the CLIΒΆ

You can change the MTU value of an OAM interface using the CLI.

If you prefer, you can use the Horizon Web interface; see Change the MTU of an OAM Interface Using Horizon.

Controller configuration changes require each controller to be locked. This requires a swact.

Procedure

  1. Lock the standby controller.

    ~(keystone_admin)$ system host-lock controller-1
    
  2. Use the system host-if-modify command to specify the interface and the new MTU value on the standby controller. This example assumes the OAM interface name as oam0.

    ~(keystone_admin)$ system host-if-modify controller-1 oam0 --imtu 1600
    
  3. Unlock the standby controller.

    ~(keystone_admin)$ system host-unlock controller-1
    
  4. Swact the controllers.

    ~(keystone_admin)$ system host-swact controller-1
    
  5. Lock the new standby controller.

    ~(keystone_admin)$ system host-lock controller-0
    
  6. Modify the MTU of the corresponding interface on the standby controller.

    ~(keystone_admin)$ system host-if-modify controller-0 oam0 --imtu 1600
    
  7. Unlock the standby controller.

    ~(keystone_admin)$ system host-unlock controller-0
