Configuring the Enhanced Cluster Features

Enhanced cluster feature overview
1) Cluster topology management function
After the cluster topology becomes stable, you can use the topology management commands on the
cluster administrative device to save the topology of the current cluster as the standard topology and
back up the standard topology on the Flash memory of the administrative device.
When errors occur to the cluster topology, you can replace the current topology with the standard
cluster topology and restore the administrative device using the backup topology on the Flash memory,
so that the devices in the cluster can resume normal operation.
With the display cluster current-topology command, the switch can display the topology of the
current cluster in a tree structure. The output formats include:
Display the tree structure three layers above or below the specified node.
Display the topology between two connected nodes.
The topology information is saved as topology.top in the Flash memory to the administrative device.
You cannot specify the file name manually.
2) Cluster device blacklist function
To ensure stability and security of the cluster, you can use the blacklist to restrict the devices to be
added to the cluster. After you add the MAC address of the device that you need to restrict into the
cluster blacklist, even if the cluster function is enabled on this device and the device is normally
connected to the current cluster, this device cannot join the cluster and participate in the unified
management and configuration of the cluster.
