How to tell if client is channel bonding from WLC end?

[GARY HAHN]

Greetings,

I'm reading that if the WLC client detail shows rates m7 - m15, then it must be a 40Mhz wide channel (bonded 20's). However, I'm seeing those rates on 2.4 clients as well, which would be impossible, since those are not bonded.   I'm looking at a 4402 running 7.0.240.0.

Is the 2.4 reading just buggy?  Different rules for 2.4 MCS?  Why doesn't Cisco simply show the Mbps like the client itself does rather than leaving us with this MCS mXX hieroglyph?

Thanks!

Gary

So long as the rate is avaialber and the client has RSSI/SNR to support it, it can connect at that rate.  There are diffferent rates for 20 vs 40 wide, as well as the guard interval.

If it's bonded, it should say that the client is connected to "an" or "bn" under "Protocol".
