To modify the MTU setting for interface groups, you must modify the MTU of the broadcast domain.

VLAN MTU size should match the broadcast domain MTU of the underlying interface groups and physical ports. If a different VLAN setting is needed for a VLAN, it must not exceed the size specified by the underlying broadcast domain.

Steps

  1. Modify the broadcast domain settings:

    broadcast-domain modify -broadcast-domain broadcast_domain_name -mtu mtu_setting

    The following warning message is displayed:

    Warning: Changing broadcast domain settings will cause a momentary data-serving interruption.
Do you want to continue? {y|n}: y

  2. Enter y to continue.

  3. Verify that the MTU setting were modified correctly:
