The MIB module for the management of a group of devices called a 'cluster'. A cluster comprises: 1. A manager device, 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 devicees, or called the cluster members throughout the context of this MIB, which are devices that can be managed via a manager device. The manager device is also considered as a cluster member. Thus it has an entry in the MIB tables defined below for cluster members. Only the manager device 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 not cross-referenced from this MIB. To determine if a particular device can be a manager device or a member device please refer to the device's user's guide.
