I have set my AP's to run at 17dBm power on wifi1.
However, some of them are only running at 14dBm and some at 12dBm.
As you can see from CLI output, ACSP is disabled.
show acsp

Wifi0 Disable(Link down) Down 20 Disable(Link down) Down Channel:No Power:No
Wifi1 Disable(User disable) 56* 20 Disable(User disable) 12* Channel:No Power:No
Here is a sample output from show interface wifi1 on an AP with 17dBm shown in GUI.
```

and here is sample output from an AP with 12 dBm shown in GUI...

Why is EIRP showing the same dBm on both APs? Both are AP230 , on channel 44 and 52. Set to Norwegian country code.
