| Starting with v1.9.0, mgmt interface details are displayed in the Cluster Network Configuration screen through the mgmt vlanconfigs. These VLAN configurations are read-only and are used only to display management interface details.

| Starting with v1.9.0, the **Cluster Network Configuration** screen displays management interface details (for all non-witness nodes) through corresponding read-only VlanConfig resources. These VLAN configurations inherit their MTU value directly from the management interface. However, changing the management interface MTU does not automatically update the MTU used by VM networks attached to the `mgmt` cluster network. To update the MTU for these VM networks, you must explicitly annotate `mgmt` as shown in the preceding example. | |
| To reset the MTU to the default value on virtual machines using the `mgmt` cluster network, remove the annotation: |

Problem:
The doc has to explicitly mention about vlanconfigs present for mgmt cluster network from v1.9.0 and users must annotate uplink-mtu annotation on mgmt cluster network to use non-default MTU values and remove the annotation to use default MTU value.
Solution:
