Wireless Access

Dear experts,

I have a simple question:
When querying via SNMP an Aruba IAP 135 (ArubaOS Version 6.2.0.0-3.2.0.4) I get the following results:

Name/OID: aiRadioChannel.XXXXXXXXXXXXX.1; Value (Integer): 11
Name/OID: aiRadioChannel.XXXXXXXXXXXXX.0; Value (Integer): 308

For the first radio interface everything is crystal clear - we have the  2,4 GHz interface w/ index 1 that is using channel 11.
The question arises when we look at the value retrieved for the interface index 0 (the 5 GHz interface), how should the value 308 be interpreted?

Thank You and Happy Holidays.

When the channel is 20MHz, the number reflects the channel number. When the channel is bonded to 40MHz, the number starts at 292 for 36+ (36 and 40) and increments by 8 for each 40MHz channel.

292 = 36+

300 = 44+ 

308 = 52+

etc

Thank You, very helpful.

Are these things documented somewhere as well?

I couldn't seem to find any documentation.
