Description: Handles physical port configuration, speed/duplex settings, and traffic statistics on Bay Networks Rapid-City series 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 RC-PORT-MIB?

RC-PORT-MIB is a Bay Networks/Nortel enterprise MIB for the Rapid-City (Accelar) switch family, providing physical port-level configuration and status management. It exposes per-port objects for connector type, speed/duplex-related routing behavior, priority, Power-over-Ethernet (PoE) status, port locking, and redundant/backup connector configuration, along with port test actions and results. Its monitoring focus is hardware status at the port level: checking rcPortActiveConnector and rcPortBackupConnectorStatus for redundant-link failover, rcPortPoe for powered-device health, and running rcPortAction-triggered tests to catch a failed or degraded physical port. As a self-contained Nortel enterprise MIB it doesn't have a strong external standards dependency, though it functions alongside standard IF-MIB interface objects for the same ports. It is deployed on Bay Networks/Nortel Rapid-City switches in enterprise wiring closets and campus networks where port-level PoE, redundancy, and physical-layer health need close tracking. Engineers can download the RC-PORT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-PORT-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 Rapid-City series switch

Monitoring Examples

An administrator would poll rcPortTable (rcPortEntry) for rcPortConnectorType and rcPortActiveConnector to verify which physical connector (e.g., primary fiber vs. backup copper) is currently active on a redundant port, with rcPortBackupConnectorStatus flagging if the backup path has failed. rcPortPoe status would be checked to confirm powered endpoints (like IP phones) are receiving power correctly. Triggering rcPortAction and reading back rcPortResult against the available rcTestTypes lets an engineer run an on-demand port diagnostic test to isolate a suspected hardware fault.

What Can Be Monitored

  • port connector type and active/backup status
  • Power-over-Ethernet (PoE) status
  • port lock state
  • port diagnostic test action/result

How to Use in IPNetwork Monitor

Example using rcPortNumStateTransition OID:

Select a Bay Networks/Nortel Rapid-City series switch (port-level config, PoE, redundancy status) 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 rcPortNumStateTransition into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports # state transitions. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
