Since this command only shows you info form the Aruba AP neighbors (and not outside neighbors). It can be helpful to determining how close the AP's are from each other.
Current Channel = 6
Neighbors on Channel 6 = 2
Power levels on Neighbors on Channel 6 = 9
SNR from Neighbors on Channel 6 = 6 and 7
When relating this output to an avg SNR your client should have. SNR > 25 @ 2.4ghz, and SNR > 30 @ 5ghz. You can tell that from the AP's perspective the neighbors on channel 6 are not anywhere close enough to create co-channel interference.
You do have 2 neighbors with SNR of 25 on channel 1, which shows that there are 2 AP's fairly close by. I personally dont use this command to review the path loss column.
Typically when I use this command I am targeting a certian area and want to get a baseline of my neighbors. This data can be skewed if there are physical obstructions between the AP's. If you can confirm that your Aruba neighbors dont have high SNR's and are still getting interference on 2.4. Then its either non-aruba SSID's, other frequences that overlap in the same specturm, or non-wifi interference.
Hope this info helps provide a bit better understanding on how this command can be useful.
