Description: Provides the base MIB framework for Bay Networks Rapid-City ERS switch management.

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 RAPID-CITY?

RAPID-CITY is the base MIB module for Bay Networks'/Nortel's Rapid City switch software, originally developed for the Accelar product family and later used across Bay Networks/Nortel Ethernet Routing Switches (ERS). It exposes core system-level configuration and status objects: system IP addressing (rcSysIpAddr, rcSysNetMask, rcSysBroadcast), SNMP community-string configuration (rcSysCommReadWriteAll, rcSysCommReadWrite, rcSysCommReadOnly), software version (rcSysVersion), an action/result command interface (rcSysAction, rcSysResult), and change-tracking timestamps (rcSysLastChange, rcSysLastVlanChange, rcSysLastStatisticsReset); these objects are registered under the RAPID-CITY OID branch inherited from the original Accelar switch software architecture. This makes it useful for monitoring both configuration and software status of the device — confirming the running software version, detecting unexpected configuration changes via the last-change timestamps, and tracking when VLAN configuration or statistics counters were last reset — though it is oriented toward system/config state rather than chassis hardware sensors like temperature. It builds on the standard SNMPv2 framework (internet, snmpModules) referenced in its OID tree. It is deployed on Bay Networks/Nortel Accelar and Ethernet Routing Switch chassis in enterprise and campus network environments.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAPID-CITY. 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 Accelar and Ethernet Routing Switch (ERS) chassis switches

Monitoring Examples

An admin would poll rcSysVersion to confirm the software release running on an Accelar/ERS switch, and watch rcSysLastChange or rcSysLastVlanChange for an unexpected timestamp update indicating an unplanned configuration change. Checking rcSysCommReadWriteAll/rcSysCommReadOnly would reveal whether default or non-standard SNMP community strings are configured, a common security audit point, while rcSysAction/rcSysResult would be used to issue and confirm the outcome of a management command like a reset or save-config operation.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using rcSysBufferUtil OID:

Select a Bay Networks/Nortel Accelar or Ethernet Routing Switch (ERS) chassis switch 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 rcSysBufferUtil into the Find box to locate it in the OID tree, then select it and click OK. It reports the system's packet buffer utilization as a percentage — the device's own description notes that a high value indicates congestion. 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 buffer utilization exceeds 80%, giving early warning of congestion before packets start being dropped. Click Finish to create the monitor; you can adjust any parameter later.

FAQ

How can I confirm the software version and recent configuration changes on a Bay Networks/Nortel Ethernet Routing Switch using RAPID-CITY?
RAPID-CITY exposes rcSysVersion for the running software version, along with change-tracking timestamps like rcSysLastChange, rcSysLastVlanChange, and rcSysLastStatisticsReset. An admin troubleshooting an ERS or Accelar switch can check these to confirm what firmware is running and detect whether configuration, VLANs, or statistics counters were reset unexpectedly.

Does RAPID-CITY expose the SNMP community strings configured on a switch?
Yes — it includes rcSysCommReadWriteAll, rcSysCommReadWrite, and rcSysCommReadOnly, along with basic system IP addressing objects (rcSysIpAddr, rcSysNetMask, rcSysBroadcast). This is useful when auditing or fixing SNMP access configuration on a Bay Networks/Nortel Accelar or ERS switch in a campus network.
