Description: Manages Cisco device clusters, providing configuration and status for cluster membership, command switches, and member switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-CLUSTER-MIB?

CISCO-CLUSTER-MIB manages Cisco device clusters, groups of switches comprising a command switch (providing a single management point via SNMP, Web Console, or CLI/Telnet) and zero or more member switches managed through it, placing it in the switch management/topology technology area. It exposes configuration and status data about cluster identity and mode, the command switch's address and identity, membership change history, and per-member status. This supports monitoring the software/management status of a switch cluster: an admin can confirm the cluster's command switch identity and mode, check the timestamp of the last membership change, review the last failure encountered when adding a member, and track individual member status via ccMemberTable, all useful for diagnosing why a switch failed to join or was dropped from a cluster. It is a self-contained Cisco cluster-management MIB without an evident dependency on another standard MIB, though it references standard SNMP transport addressing (TDomain/TAddress) for identifying the command switch and NMS. It is deployed on Cisco switches (historically Catalyst series) configured into management clusters in enterprise wiring-closet or campus network environments. Engineers can download the CISCO-CLUSTER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CLUSTER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Cisco switches (e.g. Catalyst series) configured in a management cluster

Monitoring Examples

An admin would poll ccStatusClusterName and ccStatusClusterMode to confirm cluster identity and mode, then check ccStatusCommanderTDomain/ccStatusCommanderTAddress and ccStatusCommanderMacAddress to verify which device is currently acting as command switch. ccStatusLastFailureAddMember alongside ccStatusLastNMSAddMemberTAddress would be checked when a switch fails to join the cluster, revealing the cause and the NMS that attempted the operation, while ccStatusTimeOfLastChange shows when membership last changed. ccMemberTable (via ccMemberTable's entries) would be polled against ccStatusMaxNumberOfMembers and ccStatusMemberOrder to confirm actual membership count and order match expectations.

What Can Be Monitored

  • cluster name and mode
  • command switch identity and address
  • cluster membership change timestamp
  • last member-add failure cause
  • member switch status and order
  • maximum configured cluster members

How to Use in IPNetwork Monitor

Example using ccStatusClusterMode OID:

Select a Cisco switches (e.g. Catalyst series) in a management cluster (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type ccStatusClusterMode into the Find box to locate it in the OID tree, then select it and click OK. The mode of the device. A device can become a member switch only when it is added to the cluster at the command switch. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value changes unexpectedly, since which mode is correct for this device depends on your cluster topology and an unplanned change often indicates a fault or misconfiguration. Click Finish to create the monitor; you can adjust any parameter later.
