ClientLink on a FlexConnect AP

[Alejandro.Angon]

Hello,

I have a problem configuring ClientLink on a FlexConnect local switching AP (3602i), the problem is that I can not see the clients that are using the ClientLink feature when entering the show interface dot11radio 1 lbf rbf command, the AP shows  "Hardware beamforming stats not supported (radioid 0x3B00)" message instead of show the client information. I am using a 2504 Wireless LAN Controller running 7.3.101.0 software version, do you know why is not working properly?

Well you are trying to get that information from the AP correct? Well most of that data isn't really meant to be viewed like that. All info should be viewed from the WLC. Some info is viewable but others are not.

Yes, according to the configuration guide you can see that information through the AP CLI, I have globally enable ClientLink using the config 802.11a | 802.11b beamforming global enable command into the WLC and I can see the ClientLink active status for both networks into WLC and the AP, however I´am not seeing any information about clients using this feature, do you know if  ClientLink is supported on FlexConnect AP?

thanks a lot

Yes it is supported... see the link below:

Beam forming isn't something that happens all the time, is my understanding .. Perhaps one of the Cisco guys can chime in ..

You right George. Only OFDM and if your far as hell away from the AP:)

Yea that's what I understood.. Just never went deep into the subject personally .. Also this is for legacy devices .. So if you are looking at a 802.11n client expect not to see anything

Q. What is Beamforming?

A. Beamforming (also called ClientLink) is a spatial-filtering mechanism used at a transmitter to improve the received signal power or signal-to-noise (SNR) ratio at an intended receiver (client). Beamforming uses multiple transmit antennas to focus transmissions in the direction of an 802.11a or 802.11g client, which increases the downlink SNR and the data rate to the client, reduces coverage holes, and enhances overall system performance. Beamforming is supported on Cisco Aironet 1140 and 1250 series access points and works with all existing 802.11a and 802.11g clients. It is disabled by default.
