Change the MTU of a Data Interface

You can change the value for a data interface within limits determined by the data network to which the interface is attached.

The data interface must be equal to or greater than the of the data network.

  1. Lock all hosts attached to the data network.

    1. From Admin > Platform > Host Inventory, select the Hosts tab.
    2. From the Edit menu for the standby controller, select Lock Host.

  2. On all the hosts, edit the interface to change the value.

    1. Click the name of the host, and then select the Interfaces tab and click Edit for the interface you want to change.
    2. In the Edit Interface dialog, edit the MTU field, and then click Save.

  3. Unlock all the hosts.

    From the Edit menu for the host, select Unlock Host.

    The network is updated with the new value.
