The MIB module for the management of a group of
devices called a 'cluster'.  A cluster comprises:

1. A command switch, which is a device that can provide
   a single point of management (including SNMP, Web
   Console and CLI/Telnet Console) for the devices
   in the cluster;

2. Zero or more expansion switches, or called the
   cluster members throughout the context of this MIB,
   which are devices that can be managed via a command
   switch.  The command switch is also considered as a
   cluster member.  Thus it has an entry in the MIB tables
   defined below for cluster members.

Only the command switch IP address, passwords, and SNMP
community strings need to be configured in order to
provide management access to members of the cluster.

The Entity MIB is cross-referenced from this MIB for
some of its table entries, which contain useful
information about a cluster.  For example, in the
Entity MIB, there is the logical table which contains
the community string.  This information is used to
access detailed management information for some logical
entity (the cluster, in this case).

To determine if a particular device can be a command switch
or a member switch please refer to the device's
user's guide.
