What Is ZYXEL-ES-WIRELESS?

This MIB belongs to ZyXEL's ES series switches with integrated wireless LAN capability and covers wireless configuration and monitoring, including radios, SSIDs, security settings, and connected client (station) tracking. It exposes a radio table describing per-radio configuration and status, a station table listing currently associated wireless clients, and a statistics table with traffic counters, alongside an aggregate total-station-count object. This MIB is used heavily for monitoring both software configuration and live operational status of the wireless subsystem: tracking how many clients are associated, per-radio traffic statistics, and overall wireless health, which helps detect radio outages, unusually high or low client counts, or abnormal traffic patterns. It builds on the switch's underlying interface and possibly standard IEEE802dot11-style MIB concepts for wireless-specific data, though it is a ZyXEL-specific implementation. It is typically deployed in enterprise or SMB environments using ZyXEL ES-series switches with built-in or managed wireless access for network monitoring and capacity planning. Engineers can download the ZYXEL-ES-WIRELESS file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZYXEL-ES-WIRELESS. 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.

Monitoring Examples

An administrator would poll wlanRadioTable / wlanRadioEntry to check each radio's operational status and configuration, then check wlanStationTable / wlanStationEntry to see which client devices are currently associated and to wlanTotalStationCount for an aggregate count. If wlanTotalStationCount rises far above the historical baseline for a given radio, wlanStatisticsTable / wlanStatisticsEntry counters can be checked for a spike in traffic or errors indicating congestion. A radio entry unexpectedly showing zero associated stations when clients are known to be nearby would suggest that specific radio has failed or been misconfigured.

How to Use in IPNetwork Monitor

Example using dot11FailedCount OID:

Select a ZyXEL wireless switch 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 dot11FailedCount 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 counter shall increment when an MSDU is not transmitted successfully due to the number of transmit attempts exceeding either the dot11ShortRetryLimit or dot11LongRetryLimit. 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.
