Description: Defines SNMP trap notifications for access point events and controller alarms on Enterasys RoamAbout WLAN 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 RBTWS-TRAP-MIB?

RBTWS-TRAP-MIB defines the SNMP notification (trap) objects emitted by Enterasys Networks RoamAbout wireless LAN switches (Access Controllers, AC) about events occurring on themselves and on the access points (AP) and wireless clients they manage. It exposes varbind objects carrying event context such as device and mobility-domain identifiers, AP and client MAC addresses, radio/RF signal information, authentication server details, and client session state, used within notifications rather than as standalone polled tables. In terms of status monitoring, it is primarily fault/event-oriented software monitoring: it lets an NMS learn in near-real time about wireless events like client authentication changes, rogue-transmitter (RF) detection, or session-state transitions, complementing steady-state polling of the controller's own health. It is closely tied to the broader Enterasys RoamAbout WLAN MIB family (device and client tables) whose identifiers these trap varbinds reuse. It is deployed in enterprise wireless LAN environments where Enterasys RoamAbout access controllers manage fleets of access points and need to push asynchronous alerts to a central NMS. Network engineers evaluating or troubleshooting this functionality can download the RBTWS-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RBTWS-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

  • Enterasys RoamAbout wireless LAN controllers (Access Controllers)
  • Enterasys RoamAbout access points (managed via the controller)

Monitoring Examples

A trap using varbinds such as rbtwsDeviceId, rbtwsAPMACAddress, and rbtwsAPRadioNum would tell an admin which controller and access point radio raised an event, while rbtwsRadioRssi and rbtwsRadioBSSID reveal the signal strength and BSSID observed, useful for diagnosing weak coverage or rogue AP detection via rbtwsRFDetectXmtrMacAddr. Client-oriented traps carry rbtwsClientMACAddress, rbtwsUserName, rbtwsClientAuthServerIp, and rbtwsClientSessionState, letting an operator see when a client's session moves to a failed or de-authenticated state, e.g., an authentication server unreachable at rbtwsClientAuthServerIp. rbtwsTrapsV2 is the notification group tying these together for SNMPv2 trap delivery.

What Can Be Monitored

  • wireless client authentication/session state changes
  • access point radio RSSI and BSSID
  • rogue RF transmitter detection
  • client authentication server reachability
  • per-device and per-AP event/alarm notifications
