Wireless Access

Hi,

Though dashboard --> Access points, we see the lot more information consolidated in the best possible way. 

However there are certain fields which I don't find any means to obtain through cli, like the ones of seeing "channel utilization", "Channel Quality", "Channel busy"....

Wanted to see the confirmation from TAC if there's a possible way to obtain this information from the cli as well?

The airewave is likely to be in our network few months down the line.

Through controller cli, is it not possible to see the informaion that has been reflected through gui.

I am specificially looking for info like: "channel utilization"/ "Channel Quality"/"Channel busy" for all the associated APs.

Thanks Joseph for the prompt response. 

I could see channel utilization and interference. However appears the volume of consolidated information captured via gui is not possible throught cli.

NF: Noise Floor(dBm); U: Utilization(%); I: Interference(%)
Mode: HT or VHT mode followed by Key Word "SCH" indicates that single chain mode is enabled on this radio
TD/TM/TC(*/*/*/*/*/*): "*" is the time used by Data/Mgmt/Ctrl Frames(%) in a 10 seconds time slot in the past 1 minute
AP followed by "^" indicates that spectrum monitoring is enabled on the radio in AP mode

It does not match it exactly, no.  The commandline provides information at that time, and not charts and graphs.  What other information did you want?

Obviously, its not expected the information in cli be represented in the way its done via gui( charts and graphs) :)

I was rather asking for the means to know the variety of info that is seen in GUI, can it be seen throught cli?

For instance, channel utilization and interference can be captured in "show ap radio-summary".

However there are other infos like:
SNR, Goodput, Health, Channel Quality, Channel busy ..

Which I fail to find though cli's.

Please correct me if I am missing something.

SNR of clients is in "show ap association"

Goodput and Health only show up in the GUI and are synthetic measurements.

Channel Busy is the same as channel utilization.

Thanks Joseph.

Could obtain the SNR from the cli you recommended. Is there any cli to obtain the RSSI of client as well?
