SNMP - aiRadioChannel

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.

Re: SNMP - aiRadioChannel

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.
