AggreGate Network Manager can monitor diverse wireless devices via SNMP. The required MIB files are included in the distribution bundle.
The basic tool designed for analyzing wireless device information is Wireless Information widget. Other AggreGate tools, such as events, widgets, or charts can be created for monitoring wireless SNMP-enabled devices that use non-standard MIBs.
Wireless Information Widget
The Wireless Information widget is available on any SNMP-compliant wireless device providing cDot11ActiveDevicesTable SNMP variable. To start the widget, select Wireless Information item in context menu of the device in System Tree.
The widget presents the following essential information about the selected wireless device.
| 1. | System Name and Description. System name assigned to the managed item and its textual description are read from sysName and sysDescr SNMP variables respectively. This data is displayed in the widget header. |
| 2. | Wireless Interfaces. A list of wireless (IEEE 802.11) interfaces is obtained from ifTable SNMP variable. Those are the ones having ifType equal to ieee80211 (71) value. Advanced information for every wireless interface is retrieved from cDot11ActiveDevicesTable. The following information is presented for each wireless interface: |
Field Name
|
Description
|
Source
|
Description
|
A textual string containing information about the interface. This string should include the name of the manufacturer, the product name and the version of the interface hardware/software.
|

|
Max. Stations
|
The maximum number of wireless stations which may be associate with this radio interface through the SSID. If the value is '0', the maximum number is limited only by IEEE 802.11 standard or hardware/firmware limitations. The default value is '0'.
