Description: Manages VLAN creation, port membership, and tagging configuration 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-VLAN-MIB?

RC-VLAN-MIB is a Bay Networks/Nortel "Rapid-City" enterprise MIB module used to manage VLAN configuration on the Accelar product family of Layer 2/3 switches. It exposes objects for creating and naming VLANs, assigning VLAN color-coding, enabling VLAN-based routing, mapping VLANs to interface indexes, and configuring Spanning Tree Group (STG) association and Super VLAN (SVLAN) settings. As a monitoring resource it is used chiefly to confirm the software configuration state of the switch's VLAN topology - e.g., how many VLANs exist, their names, routing-enabled status, and STG membership - which helps operators detect VLAN misconfiguration or unintended routing/bridging behavior rather than hardware faults. It ties into IEEE 802.1Q VLAN and 802.1D Spanning Tree standards, correlating with the switch's underlying bridge and interface tables. It is deployed on Nortel/Bay Networks Accelar (Rapid-City) switches in enterprise campus or data-center networks for VLAN segmentation and routing configuration. Engineers can download the RC-VLAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-VLAN-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

  • Nortel/Bay Networks Accelar (Rapid-City) switch

Monitoring Examples

An administrator would poll rcVlanNumVlans for a quick count of configured VLANs, then walk rcVlanTable/rcVlanEntry (keyed by rcVlanId) to check rcVlanName, rcVlanRoutingEnable, and rcVlanStgId for each VLAN, confirming routing is enabled only on the intended VLANs and that spanning-tree group assignments are correct. Issuing a change via rcVlanAction and checking rcVlanResult reveals whether a VLAN configuration change (add/delete/modify) succeeded or failed, which would explain an unexpected VLAN topology change on the switch.

What Can Be Monitored

  • VLAN count
  • VLAN name and ID
  • VLAN routing-enabled state
  • spanning tree group (STG) assignment
  • super VLAN global settings

How to Use in IPNetwork Monitor

Example using rcVlanNumVlans OID:

Select a Nortel/Bay Networks Accelar (Rapid-City) switch (VLAN/STG/SuperVLAN configuration) 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 rcVlanNumVlans into the Find box to locate it in the OID tree, then select it and click OK. The number of VLANs currently defined in the 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 Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
