If the management device of a cluster is a slave device in an XRN fabric, the standard topology
information is saved only to the local Flash of the master device in the XRN fabric.

Configuring cluster device blacklist

Follow these steps to configure the cluster device blacklist on a management device:
To do… Use the command… Remarks
Enter system view system-view —
Enter cluster view cluster —
Add the MAC address of a
specified device to the cluster
blacklist
black-list add-mac
mac-address
Optional
By default, the cluster blacklist
is empty.
Delete the specified MAC

Displays the information about
the devices in the cluster
blacklist display cluster black-list
Optional
This command can be
executed in any view.
Configuring the Cluster Synchronization Function
After a cluster is established, to simplify the access and management to the cluster, you can
synchronize the SNMP configurations on the management device and the local user configurations to
the member devices of the cluster by configuring the cluster synchronization function.

SNMP configuration synchronization

With this function, you can configure the public SNMP community name, SNMP group, SNMP users
and MIB views. These configurations will be synchronized to the member devices of the cluster
automatically, which not only simplifies the configurations on the member devices, but also enables the
network management station (NMS) to access any member device of the cluster conveniently.
For the SNMP configurations, refer to the SNMP-RMON Operation part in this manual.
