Description: Manages Apple AirPort Base Station 3 wireless access point configuration, client associations, and network status.

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 AIRPORT-BASESTATION-3-MIB?

AIRPORT-BASESTATION-3-MIB is Apple's vendor MIB for the third-generation AirPort and AirPort Extreme Base Station wireless access points, exposing system identity/configuration and wireless client association data. It covers system-level configuration objects (name, contact, location, uptime, firmware version) alongside a wireless client table reporting each associated station's address, connection type, and data rates. Its monitoring value spans both software status — sysConfUptime and sysConfFirmwareVersion reveal device availability and whether firmware is current — and wireless service status, since wirelessNumber and wirelessClientsTable/wirelessClient rows show how many stations are associated and their per-client physical address, association time, and negotiated rates. It is a self-contained vendor MIB built on standard SNMPv2-SMI conventions rather than layered on IEEE 802.11 MIBs. It is deployed in home/small-office and some enterprise environments using Apple AirPort Base Station access points for Wi-Fi connectivity. Engineers can download the AIRPORT-BASESTATION-3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AIRPORT-BASESTATION-3-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

Apple AirPort / AirPort Extreme Base Station (v3)

Monitoring Examples

An administrator would poll sysConfUptime and sysConfFirmwareVersion to confirm the base station hasn't rebooted unexpectedly and is running current firmware. Polling wirelessNumber alongside wirelessClientsTable/wirelessClient rows (with wirelessPhysAddress, wirelessType, wirelessDataRates, and wirelessTimeAssociated) would show which client devices are currently connected, their negotiated data rate, and how long they've been associated — useful for spotting a client stuck at a low data rate due to poor RF conditions. A sudden drop in wirelessNumber could indicate the radio or the base station itself has gone offline.

What Can Be Monitored

system uptime
firmware version
number of wireless clients
per-client MAC address and association time
per-client data rate
system identity (name/contact/location)

How to Use in IPNetwork Monitor

Example using sysConfUptime OID:

Select an Apple AirPort/AirPort Extreme Base Station (v3) (legacy) 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 sysConfUptime into the Find box to locate it in the OID tree, then select it and click OK. It reports the length of time, in seconds, the AirPort Base Station has been running. 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 the value is unexpectedly low (e.g. under 10 minutes), since that indicates a recent, possibly unplanned, reboot or restart. Click Finish to create the monitor; you can adjust any parameter later.
