Basic command output question

All,

 

This is most probably a simple question re the output of this command:-

 


(LHRR1-DC-WIFI1) # show ap association client-mac 00:21:6a:53:e6:0e

Flags: W: WMM client, A: Active, K: 802.11K client, B: Band Steerable

PHY Details: HT: High throughput; 20: 20MHz; 40: 40MHz
             <n>ss: <n> spatial streams

Where it shows channel noise 88 and SNR 29, does this equate to RSSI being 59? i.e is  'channel noise' the same as the noise floor? When I run 'inssider' the rssi from that mac to the same AP shows as 50... I am wondering is this just that inssider is unreliabe or I have misconstrued 'channel noise'?

 

Thanks.

EDIT:  I typed to quickly.

 

Channel Noise is the noise floor.

Re: Basic command output question

Client SNR is in RSSI? Not sure what that means, SNR is the difference between background noise and signal strength which is measure in RSSI on Inssider for example isnt it?

 

The measurements are take from Inssider on my laptop which shows my mac's rssi from the AP that is also shown on the command.

 

But is 'channel noise' as shown in the command the same as the noise floor measurement? Or am I looking at two different things?

Re: Basic command output question

Noise is noise floor, correct.

 

SNR does = power-noise floor, yes.

 

What version of ArubaOS is this and what access point?
