Aironet 1250 channel bonding - config 802.11a chan_width

[g.rienstra]

Hi ,

I tried to bond two 20MHz channels on a 1250 (802.11A - LWAPP - 12.4(10b)JA) but get the following error:

' Slot is not Disabled or Customize is not enabled'

I have disabled the 802.11network/ radios etcetc but no luck yet.

You can not club to channels for usage with wireless network. You only have an option to add a channel available to be allocated. You use the command config 802.11 channel ap for this purpose.

I am having the same issue while in LWAP mode.

According to this document:

http://www.cisco.com/en/US/solutions/collateral/ns340/ns394/ns348/ns767/white_paper_80211n_design_and_deployment_guidelines.html

40mhz is supported on WLC's, it even gives steps on how to enable it, but I am receiving the same error as the original poster.

I was able to successfully deploy 802.11n @ 40mhz in autonomous mode, but the operation fails in LWAP mode.

I am going to open a TAC case to see if this is a bug.

You have to set the channel first then change the channel width. You might have to set the power also...

If you want to set above 40MHz use these channels: 36,44,52,60,100,108,116,132,149.157

If you want to set below 40MHz use these channels: 40,48,56,64,104,112,136,153,161

Hope this helps.

Hi Jeremy, I see your post is very old but I wanted to reply in case Cisco TAC was able to solve your issue and ask if you know of a way to set the Channel Width with Templates or CLI.

Thanks

Hi Ed,

Did you try something like below. Replace your AP name with LAP1 below.

(5508-1) >config 802.11a disable LAP1
(5508-1) >config 802.11a chan_width LAP1 40 
(5508-1) >config 802.11a enable LAP1

(5508-1) >save config 

Are you sure you want to save? (y/n) y

The AP I was testing was on the wrong channel for 40mhz width.

I am sorry to say that you cannot mix the channel 20MHz channels on a 1250 (802.11A - LWAPP - 12.4(10b)JA)

Yes i tested.

Try this from Controller console.

First disable the 802.11a then mention the below commands for your LAP.

config 802.11a chan_width LAP1 40 

config 802.11a enable LAP1

save config 

hope this will work.

Note: If problem persist ,reimage the lap and try again.
