Configuring enhanced beacons and probes

Configuring the beacon table
The Beacon Table is used to detect rogue APs. An adopted 7131N-FGR in dependent mode
transmits beacons and MUs send a probe request to the AP for association. The adopted
7131N-FGR in dependent mode (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 168 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.
To configure enhanced beacons:
1. Select Security > Enhanced Probe/Beacon Table from the main menu tree.
2. Select the Beacon Table tab.
