Description: Monitors Token Ring port and ring master status for ring topology management on Nortel Centillion 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 CENTILLION-PORT-RING-MASTER-MONITOR-MIB?
CENTILLION-PORT-RING-MASTER-MONITOR-MIB is a Bay Networks (Centillion, later Nortel) proprietary MIB reporting Token Ring port-ring master status for change-tracking purposes. Its objects cover the sysUpTime of the last Port Ring Master table change, and a master table (slot number, port number, IP address, MAC address) identifying the active ring master per port. As a status MIB it lets an administrator confirm which station is currently the active ring master (Active Monitor) on a Centillion Token Ring segment and when that last changed. It is deployed on Bay Networks (Nortel) Centillion Token Ring switches. Engineers can download the CENTILLION-PORT-RING-MASTER-MONITOR-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CENTILLION-PORT-RING-MASTER-MONITOR-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
- Bay Networks (Nortel) Centillion Token Ring switches
Monitoring Examples
An administrator checks portRmTable and portRmLastChg to confirm which station is the current ring master and when that last changed on a Centillion Token Ring segment.
What Can Be Monitored
- Token Ring port-ring master identity and last-change time
