Cisco WLC GUI doesn't show Radio Power Levels

dot1x — Mon, 05 Jul 2021 15:35:14 GMT

Hi All,

I'm trying to check the radio power levels on 2 different WLCs running v8.3.

In one of the controllers, when I go to WIreless>>802.11a/n/ac Radios, I can see the Power Levels.

Whereas, on the other controller, it doesn't show the power levels, instead it has some Load Profile, Interference Profile columns. (Please see attached).

Could someone please assist?

Thanks.

Exactly what version of 8.3?

Uhmmmm ... I'd be upgrading first and see if it's made some improvements.

Thanks Leo.
Since we are not managing the customer's controllers, we can't upgrade.
I used CLI command to check the power levels: show advanced 802.11a txpower

Tx Power Available Power Levels
*6/8 ( 8 dBm) [23/20/17/14/11/8/5/2]
*4/5 ( 6 dBm) [15/12/9/6/3/3/3/3]

I understand that these 2 APs are operating at power level 6 and 4. What does 8 and 5 mean here?
Since Power Level 1 is the highest power level, does it mean the lowest power APs could go are 8 and 5?

Updating the case:

When you go to Monitor >> Access Points >> Radios >> 802.11a/n/ac or 802.11b/g/n

you won't see the power levels.

You see the power levels when you go to:

Wireless >> Access Points >> Radios >> 802.11a/n/ac or 802.11b/g/n

Hope it would help others too.
