What Is CAMBIUM-PMP80211-MIB?

CAMBIUM-PMP80211-MIB is a Cambium Networks enterprise MIB for the PMP (Point-to-MultiPoint) family of 802.11-based wireless broadband access points and subscriber modules. It exposes general device identity and software/hardware version information, current date/time, system uptime, the wireless MAC address, and radio-specific operational parameters such as DFS (Dynamic Frequency Selection) status, synchronization source, country code, antenna gain, TDD ratio, and effective SSID. Its monitoring emphasis spans both software status (uptime, software version) and radio/hardware operating state, letting an operator confirm the AP's firmware version, how long it has been running since last restart, and whether its RF configuration (channel, sync source, DFS) is currently as expected. It is a self-contained Cambium-proprietary schema without an evident dependency on external wireless standard MIBs. It is deployed on Cambium PMP 802.11 access points and subscriber modules in fixed wireless broadband access networks. Network engineers evaluating or troubleshooting this functionality can download the CAMBIUM-PMP80211-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CAMBIUM-PMP80211-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

  • Cambium PMP 802.11 access point
  • Cambium PMP subscriber module
  • Cambium Networks PMP (Point-to-MultiPoint) 802.11 fixed-wireless broadband access points and subscriber modules

Monitoring Examples

An operator would poll cambiumSystemUptime and cambiumCurrentSWInfo to confirm the AP's uptime and firmware version match expectations after a maintenance window. Checking cambiumDFSStatus alongside cambiumEffectiveSyncSource and cambiumEffectiveCountryCode reveals whether the radio has been forced off a channel by radar detection or is using an unexpected synchronization source, both are common causes of unexplained link drops. Reviewing cambiumEffectiveTDDRatio and cambiumEffectiveAntennaGain against provisioned values helps confirm the RF configuration wasn't altered from its intended setting.

What Can Be Monitored

  • system uptime
  • software/hardware version
  • DFS status
  • sync source
  • effective SSID/TDD ratio/antenna gain

How to Use in IPNetwork Monitor

Example using cambiumEthRXBytes OID:

Select a Cambium Networks wireless broadband equipment 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 cambiumEthRXBytes into the Find box to locate it in the OID tree, then select it and click OK. It reports the total Ethernet RX bytes Device Allocation: AP, SM. 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, 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.
