Description: Cisco LWAPP extended notifications and event objects for access points, WLANs, and wireless clients on Cisco wireless LAN controllers

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 CISCO-LWAPP-EXT-MIB?

CISCO-LWAPP-EXT-MIB provides extended configuration, status, and notification objects for Cisco wireless LAN controllers that terminate the Light Weight Access Point Protocol (LWAPP) tunnel from lightweight access points. It belongs to the Cisco enterprise wireless networking area, specifically covering controller-level system management, port operational state, and the web portal server used for guest/authentication redirects. It exposes general system data such as agent reset/clear-config actions, current system time, per-port operational status and interface speed/last-change timers, alongside notification objects for extended WLAN events. It is notably useful for monitoring hardware/software status such as controller uptime-adjacent counters (clExtIfSinceLastChange), physical port operational status (clExtPortOperStatus), and system-level actions like resets or configuration clears that indicate administrative or fault-driven state changes. This MIB depends on and extends the base CISCO-LWAPP-MIB framework and is deployed on Cisco wireless LAN controllers (e.g., 4400/5500/WiSM series) in enterprise Wi-Fi deployments. Engineers can download the CISCO-LWAPP-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-LWAPP-EXT-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

  • Cisco Wireless LAN Controller (WLC)

Monitoring Examples

An administrator polls clExtIfTable/clExtIfEntry for clExtIfOperStatus and clExtIfSinceLastChange on controller physical ports to detect an unexpected link flap or a port that has stayed down since a change. Monitoring clExtSysMaxNewConnectionPerSecond alongside clExtPortModeConfigTable settings helps confirm the controller isn't throttling new client connections due to a configured rate limit during a connectivity storm.

What Can Be Monitored

  • controller port operational status
  • interface speed and last-change time
  • system reset/clear-config events
  • max new connections per second
  • system current time

How to Use in IPNetwork Monitor

Example using clExtApDot11RadioStatsRxByteCount OID:

Select a Cisco wireless LAN controller 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 clExtApDot11RadioStatsRxByteCount 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. This object represents the total bytes of packets received on the radio. 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 Counter64-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 (in bytes), 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.
