Switch between management 
device and member device 

cluster switch-to 
{ member-number | 
mac-address H-H-H | 
administrator } 

Optional 

You can use this command 
switch to the view of a member 
device and switch back. 

Configure the MAC address of 
the management device 

administrator-address 
mac-address name name 

Optional 

By default, a switch does not 
belong to any cluster. 

Trace a device through MAC 
address or IP address 

tracemac { by-mac 
mac-address vlan vlan-id | 
by-ip ip-address } [ nondp ] 

Optional

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: 

z 

Display the tree structure three layers above or below the specified node.  

z 

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.
