6.10 Configuring Enhanced Beacons and Probes
The switch can be configured to detect and locate rogue APs and MUs. Refer to Editing AP Settings on page 4-95 to enable
an AP to forward beacons and association information for AP radios to detect a rogue. An AP can also be configured to
forward MU probe requests to the switch to help locate a rogue MU.
Use the Enhanced Beacons/Probe screen to configure enhanced beacons/probes and their output reports. The Enhanced
Probes and Beacons screens displays four tabs supporting the following configuration activities:
• Configuring the Beacon Table
• Configuring the Probe Table
• Reviewing Found Beacons
• Reviewing Found Probes
6.10.1 Configuring the Beacon Table
The Beacon Table is used to detect rogue APs. An AP300 transmits beacons and MUs send a probe request to the AP for
association. The AP300 (on receipt of the probe request) sends a probe response and forms an AP-MU association.
When enabling an Enhanced Beacon, the switch allows adopted Access Ports to periodically scan for rogue APs on
different channels without disassociating MUs. The beacons collected in the scan are passed on to the switch so required
information is gathered to locate a particular rogue AP. Refer to
Editing AP Settings on page 4-95 to enable an AP to
forward beacons and association information for AP radios to detect a rouge.
The switch is provided with a set of 802.11a and 802.11bg radio specific channels. The switch radio scans scan each
channel to detect the potential existence or rogues operating on the configured channel. On completion of a scan, the
switch moves the AP back to its original channel.
If, during the scan, an AP is detected on a different channel (due to a leaked signal), this channel is also added to the
channel set. The AP sends this information to the switch, which maintains a table with the following information:
• MAC address of the detected rogue AP
• AP MAC address
• Signal strength of the detected rogue AP
• Channel on which the AP was detected
• Time when the AP was detected.
This information is used by the Motorola Solutions RF Management application (or Motorola Solutions RFMS) to locate
the rogue AP. Motorola Solutions RFMS uses this information to physically locate the position of rogues and authorized
devices within a site map representative of the physical dimensions of the actual device deployment area.
To configure enhanced beacons:
1. Select Security > Enhanced Probe/Beacon Table from the main menu tree.
NOTE: Currently, only an AP300 model Access Port supports enhanced beacons and
probes request forward configuration.
