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.
