Configuring the probe table

Define enhanced probes to detect rogue Clients within the network. A Mobility 300 transmits
beacons and the Clients sends a probe request to the AP for association. A Mobility 300 (on receipt
of the probe request) sends a probe response and associates to the Client.
When using an enhanced probe, a Mobility 300 sends a probe response to the Client to associate.
At the same time, the AP forwards the Client's probe request information to the controller. The
controller maintains a table of the probe requests the Mobility 300 receives from Clients.
To configure enhanced beacons:
1. Select Security > Enhanced Probe/Beacon Table from the main menu tree.
2. Select the Probe Table tab.
