Client link is now called beam forming in the 7.2 release.

This can be done via cli of the wlc only.        

Currently the only way to enable Beamforming (Client-Link) on 7.2 is to use

the below CLI command

config {802.11a | 802.11b} beamforming global {enable | disable}

Please see below on how to configure this via the cli of the wlc:

config 802.11 beamforming

To enable or disable beamforming on the network or on individual radios, enter the config 802.11 beamforming command.

config 802.11{a | b} beamforming {global | ap ap_name} {enable | disable}

Usage Guidelines

When you enable beamforming on the network, it is automatically enabled for all the radios applicable to that network type.

Follow these guidelines for using beamforming:

*Beamforming is supported only for legacy orthogonal frequency-division multiplexing (OFDM) data rates (6, 9, 12, 18, 24, 36, 48, and 54 mbps).

NoteBeamforming is not supported for complementary-code keying (CCK) data rates (1, 2, 5.5, and 11 Mbps).

*Beamforming is supported only on access points that support 802.11n (AP1250 and AP1140).

*Two or more antennas must be enabled for transmission.

*All three antennas must be enabled for reception.

*OFDM rates must be enabled.

If the antenna configuration restricts operation to a single transmit antenna, or if OFDM rates are disabled, beamforming is not used.


This example shows how to enable beamforming on the 802.11a network:

> config 802.11a beamforming global enable

This is absent from 7.2 configuration guide and release notes


what happens if I have 2 APs configured for beamforming if one AP already have 15clients, will the next client go to the 2nd AP to form beamforming?
