Cisco AIR-AP1832i

[George Rodriguez]

I have an 1832i that I'd like to use on a WLC 5508. Is this possible? Do I need to change the IOS on the AP or is already provisioned to use either a WLC or the Mobility Express?

[Vengatesa Prasath]

yes it is possible..

Run "show version" on CLI 

If the show version CLI displays AP Image Type: MOBILITY EXPRESS IMAGE and AP Configuration: MOBILITY EXPRESS CAPABLE, it operates both as Controller and an Access Point. It participates in the Master Election process in case of a failover.

So based on your response and the output of the AP it looks like I can use it on a WLC 5508. Does it operate the same as the older models where it does a broadcast capwapp looking for a controller?

I am Sorry..

Currently your AP1832 is running in ME mode. You have to convert that to AP so that it can join 5508.

[George Rodriguez]

you stated that if the show version shows this:

AP Image type : MOBILITY EXPRESS IMAGE
AP Configuration : MOBILITY EXPRESS CAPABLE

then I do not have to convert the image.

I'm confused.

[Vengatesa Prasath]

I made a mistake in my first post. 

Currently your 1832I running in mobility Express mode. 1832I wont join 5508 when it runs in Mobility Express mode.

If you want the AP1832 to join 5508, then you have to convert it to Capwap mode. 

Follow below link and convert your 1832I to Capwap:

seems to be doing the broadcast now. I'll try on the network.

Cool .. It should join the 5508..

Let us know how it goes.

Post the complete output to the following commands: 

1.  WLC:  sh sysinfo; 

2.  WLC:  sh time; 

3.  AP:  sh version; and

4.  AP:  sh ip interface brief

Is DHCP Option 43 enabled?
