Description: Defines SNMP traps for AP state changes, client events, and controller fault conditions on Nortel NTWS platforms.

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 NTWS-TRAP-MIB?

NTWS-TRAP-MIB is the fault/event notification MIB for Nortel's NTWS wireless LAN platform, defining the SNMP traps the Access Controller and its Access Points emit for state changes, client events, and controller fault conditions. Its varbind objects carry contextual data for these traps, including device and mobility-domain identifiers, AP and client MAC addresses, detected rogue-transmitter MAC address, port and radio number, RSSI, BSSID, username, authentication server IP, and client session state. As a notification-focused MIB it is squarely about software/operational status monitoring: it is how the controller proactively alerts a management station to AP up/down transitions, client authentication or session-state changes, RF/rogue detection events, and other fault conditions, rather than requiring constant polling. It is designed to work hand-in-hand with the data-oriented NTWS MIBs in this family (NTWS-AP-STATUS-MIB, NTWS-CLIENT-SESSION-MIB, and NTWS-INFO-RF-DETECT-MIB), since its trap varbinds reference the same identifiers (AP serial/MAC, client MAC, RF transmitter MAC) defined there. It is deployed on Nortel NTWS wireless controllers as the real-time alerting layer of an enterprise WLAN deployment. Engineers can download the NTWS-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NTWS-TRAP-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 NTWS wireless LAN controllers (Access Controllers) and managed Access Points

Monitoring Examples

A trap carrying ntwsAPMACAddress and ntwsPortNum together with a state-change indication would alert an operator that a specific AP just went down, while a trap including ntwsClientMACAddress, ntwsUserName, and ntwsClientSessionState would signal a client authentication or session event needing attention. A burst of traps referencing ntwsRFDetectXmtrMacAddr and ntwsRadioRssi in a short window would reveal a wave of newly detected RF transmitters, prompting investigation into a potential rogue AP incident.

What Can Be Monitored

  • AP state-change events
  • client authentication/session events
  • rogue/RF transmitter detection events
  • client RSSI at time of event
  • controller fault conditions
  • mobility domain and device identifiers in alerts
