CIDR Block of the Cluster Management Plane

Check Items

Check whether the CIDR block of the cluster management plane is the same as that configured on the backbone network.

Solution

The CIDR block of the management plane has been modified in your region. As a result, the CIDR block of the management plane and that of the backbone network are inconsistent.

Submit a service ticket to contact technical support to modify the settings, and recheck the configurations.
