11 Select the radio profile you created and click the properties button. The Radio Profile Properties dialog
box is displayed.
12 To enable countermeasures against rogues detected by radios managed by this profile, select one of the
following from the Countermeasures Mode pull-down list:
•
None—Radios do not use countermeasures. This is the default.
•
All—Radios use countermeasures against devices classified by WSS Software as rogues and
against devices classified by WSS Software as interfering devices.
against devices classified by WSS Software as interfering devices.
A rogue is a device that is in the Nortel network but does not belong there. An interfering device is
not part of the Nortel network but also is not a rogue. WSS Software classifies a device as an
interfering device if no client connected to the device has been detected communicating with any
network entity listed in the forwarding database (FDB) of any WSS in the Mobility Domain.
Although the interfering device is not connected to your network, the device might be causing RF
interference with AP radios.

Configured—Causes radios to attack only devices specified in the attack list on the WSS
(on-demand countermeasures). When this option is used, devices found to be rogues by other
means, such as policy violations or by determining that the device is providing connectivity to
the wired network, are not attacked.

13 To disable active scanning for rogue devices, deselect Enable Active Scan.
When active scan is enabled, radios send probe any requests (probe requests with a null SSID name), to
solicit probe responses from other access points. Radios also passively scan by listening for beacons and
probe responses. When active scan is disabled, radios perform passive scanning only.

Caution!
Countermeasures affect wireless service on a radio. When an AP
radio is sending countermeasures, the radio is disabled for use by network traffic,
until the radio finishes sending the countermeasures.
