Brocade provides full life-cycle support for either a new or existing 802.11n mobility deployment,
from network design to day-to-day support. For information on deploying your 802.11n radio, see

“Configuring the 802.11a/n or 802.11b/g/n radio”

on page 142.

Sensor support

The Brocade Wireless Intrusion Protection System (WIPS) protects your wireless network, mobile
devices and traffic from attacks and unauthorized access. WIPS provides tools for standards
compliance and around-the-clock 802.11a/b/g wireless network security in a distributed
environment. WIPS allows administrators to identify and accurately locate attacks, rogue devices
and network vulnerabilities in real time and permits both a wired and wireless lockdown of wireless
device connections upon acknowledgement of a threat.

An access point radio can function as a sensor and upload sensor mode operation information to a
dedicated WIPS server. WIPS is not supported on a WLAN basis, rather sensor functionality is
supported on the access point radio(s) available to each WLAN. When an access point radio is
functioning as a WIPS sensor, it is able to scan in sensor mode across all channels within the 2.4
and 5.0 GHz bands.

NOTE

Sensor support requires an AirDefense WIPS Server on the network. Sensor functionality is not
provided by the access point alone. The access point works in conjunction with a dedicated WIPS
server.

The following is a network topology illustrating how a sensor functions within an access point
supported wireless network:
