OUNTERMEASURES

When a MAP radio detects radar on a channel, the radio switches to 
another channel and does not attempt to use the channel where the 
radar was detected for 30 minutes. MSS also generates a message.

You can enable MSS to use countermeasures against rogues. 
Countermeasures consist of packets that interfere with a client’s ability to 
use the rogue. 

Countermeasures are disabled by default. You can enable them on an 
individual radio-profile basis. When you enable them, all devices of 
interest that are not in the known devices list become viable targets for 
countermeasures. Countermeasures can be enabled against all rogue and 
interfering devices, against rogue devices only, or against devices explicitly 
configured in the WX switch’s attack list. The Mobility Domain’s seed 
switch automatically selects individual radios to send the countermeasure 
packets.

RF Detection requires the Mobility Domain to be completely up. If a 
Mobility Domain is not fully operational (not all members are up), no new 
RF Detection data is processed. Existing RF Detection information ages 
out normally. Processing of RF Detection data is resumed only when all 
members of the Mobility Domain are up. If a seed switch in the Mobility 
Domain cannot resume full operation, you can restore the Mobility 
Domain to full operation, and therefore resume RF Detection data 
processing, by removing the inoperative switch from the member list on 
the seed.
