wlc 5508 join new AIR-LAP1142 access point

[as00001111]

Hey guys,

I have a central 5508 wlc and a lof of access points in branch offices.

Branch offices are connected via Site to Site VPN.

All AIR-LAP1142 access points in our branch offices are connected to the central wlc.

Now, we got a new branch office for which I prepared a new access point.

What I did on the ap:

lwapp ap ip address 10.10.10.10 255.255.255.0

lwapp ap ip default-gateway 10.10.10.254

lwapp ap controller ip address 192.168.1.10

My problem now is that the ap doesn't connect to the wlc.

Are there any commands to force the connection?

I can ping the ap, there are no connectivity issues.

Am I missing configuration steps.

Where should the ap appear in wlc gui?

Thank you very much!

What version software does your WLC run, the LWAPP command normally is used for legacy code. You should rather use the CAPWAP command as it's discovery process is much more robust than LWAPP and have dynamic MTU.

Are you sure you have your subnet mask is correct or was this just a typo on the post? 

[as00001111]

wlc does run software version 8.5.151.0.

I wanted to use CAPWAP command but it's not available. Is that normal?

Only lwapp command is available.

(You are right, that was a typo. I fixed it.)

1140 is not supported after 8.4.X.X (and later).

@Leo Laohoo 

Sorry I gave you a wrong information.

Software version on wlc is 8.3.150.0

How shall I proceed? capwap command is not available on the ap, only lwapp.

Most likely the code you run on the AP must be very old that don't support that CAPWAP command. The bigger problem you have as mentioned by @Leo Laohoo is your software version on the WLC.

You will need to check out the device Cisco Wireless Solutions Software Compatibility Matrix

Always double-check the release notes of the WLC software code versions as they will indicate what AP's are supported.

You can't use the capwap command once the ap has joined a controller. You need to factory default the ap if you want to use it.

[as00001111]

I did a factory reset but couldn't use the capwap command. There is only lwapp command available.

Post the complete output to the following commands:
1. AP: sh version;
2. AP: sh ip interface brief;
3. WLC: sh sysinfo; and
4. WLC: sh time

Based on the serial number of the AP, I can determine the AP to be >10 years old.  

Did anyone read this:  Field Notice: FN - 63942 - Wireless Lightweight Access Points and WLAN Controllers Fail to Create CAPWAP/LWAPP Connections Due to Certificate Expiration

[Scott Fella]

Since the ap is a LAP1142, that is defined as an lwapp ap and the capwap command is only available in the newer models.  The command does the same thing, it just depends on the model.

From the Branch do you have reachability to Controller IP, you able to ping from Branch network this first steps to check. ?
