Configures an AirDefense sensor server on this RF Domain. Sensor servers allow network administrators to monitor and download data from multiple sensors remote locations using Ethernet TCP/IP or serial communications. This enables administrators to respond quickly to interferences and coverage problems.

Access point radios can function as a sensor and upload information to a dedicated AirDefense server (external to the controller). Unique AirDefense server configurations can be used by RF Domains to ensure a WIPS server configuration is available to support the unique data protection needs of individual RF Domains. The access point works in conjunction with a dedicated AirDefense server forms a Wireless Intrusion Protection System (WIPS).

WIPS protects the controller managed network, wireless clients and access point radio traffic from attacks and unauthorized access. WIPS provides tools for standards compliance and around-the-clock 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 acknowledgment of a threat.

WIPS is not supported on a WLAN basis, rather sensor functionality is supported on the access point radio(s) available to each controller managed WLAN. When an access point radio is functioning as a WIPS sensor, it is able to scan in sensor mode across all legal channels within the 2.4 and 5.0 GHz bands. Sensor support requires a 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.



Starting with the WiNG 7.2.0 release, AP5XX model access points are capable of capturing WPA3 frames in the sensor mode. For more information, see rf-mode.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000

sensor-server <1-3> ip <IP/HOSTNAME> {port [443|<1-65535>]}
Sensor-server <1-3> Configures the AirDefense sensor server parameters
  • <1-3> – Select the server ID from 1 - 3. The server with the lowest defined ID is reached first. The default is 1.
ip <IP/HOSTNAME> Configures the (non DNS) IPv4 address of the sensor server
  • <IP/HOSTNAME> – Specify the sensor server‘s IPv4 address or hostname.
port [443|<1-65535>] Optional. Configures the sensor server port. The options are:
  • 443 – Configures port 443, the default port used by the AirDefense server
  • <1-6553> – Allows you to select a WIPS/AirDefense sensor server port from 1 - 65535
