Beamforming (ClientLink)

Enable

ClientLink

if using Cisco 802.11n capable Access Points.

For releases prior to 7.2.103.0,

ClientLink

can be enabled globally via the 802.11 Global Parameters section or on individual

access points via the access point’s 802.11 radio configuration page.
As of release 7.2.103.0,

ClientLink

is no longer configurable via the Cisco Wireless LAN Controller’s web interface and is

only configurable via command line.

With releases 7.2.103.0 and later use the following commands to enable the beamforming feature globally for all access points
or for individual access point radios.

(Cisco Controller) >config 802.11a beamforming global enable
(Cisco Controller) >config 802.11a beamforming ap <ap_name> enable
(Cisco Controller) >config 802.11b beamforming global enable

(Cisco Controller) >config 802.11b beamforming ap <ap_name> enable

The current status of the beamforming feature can be displayed by using the following command.

(Cisco Controller) >show 802.11a
(Cisco Controller) >show 802.11b

Legacy Tx Beamforming setting....................
