H3C S5600 Series Operation Manual page 842

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.
Configuring the enhanced cluster features
Complete the following tasks to configure the enhanced cluster feature:
Configuring cluster topology management function
Configuring cluster device blacklist
Configuring cluster topology management function
1) Configuration prerequisites
Before configuring the cluster topology management function, make sure that:
The basic cluster configuration is completed.
Devices in the cluster work normally.
2) Configuration procedure
Follow these steps to configure cluster topology management function on a management device:
To do...
Enter system view
Enter cluster view
Check the current topology and
save it as the standard topology.
Save the standard topology to the
Flash memory of the administrative
device
Task
Use the command...
system-view
cluster
topology accept { all [ save-to local-flash ]
| mac-address mac-address | member-id
member-id | administrator }
