look for rogue devices by sending probe any frames (probes with a null

Scan

SSID name), to solicit probe responses from other APs.

 

Active scan is enabled by default. You can disable or reenable the feature

 

on an individual radio profile basis. To disable or reenable active scan on a

 

radio profile, use the following command:

 

set radio-profile name active-scan {enable disable}

 

The following command disables active scan in radio profile radprof3:

 

WX1200# set radio-profile radprof3 active-scan disable

 

success: change accepted.

 

 

Enabling MAP

A MAP signature is a set of bits in a management frame sent by a MAP

Signatures

that identifies that MAP to MSS. If someone attempts to spoof

 

management packets from a 3Com MAP, MSS can detect the spoof

 

attempt.

 

MAP signatures are disabled by default. To enable or disable them, use

 

the following command:

 

set rfdetect signature {enable disable}

 

The command applies only to MAPs managed by the WX switch on

 

which you enter the command. To enable signatures on all MAPs in a

 

Mobility Domain, enter the command on each WX switch in the Mobility

 

Domain.

 

You must use the same MAP signature setting (enabled or disabled) on all

 

WX switches in a Mobility Domain.
