When I checked before, there

jvasilko · ‎03-23-2017

I am having an issue with getting some new 3702i APs to join a new 5520 WLC. I am trying to add about 180 Aps to this controller and none of them join. I see them trying to join in the AP Join section, but all are unsuccessful. I have another new 5520 at a different site that I had one AP try to connect to, and it successfully joined without issue.

Both controllers are running the same version of code (8.2.141) and have the same configuration aside from local IP addressing. The clock looks to be set to the proper time (using NTP) and the Aps can ping the WLC that will not allow them to join.

When I did a debug capwap event, I was immediately deluged with output from all of the Aps trying to join. One of the lines of output that was related to all was Disconnecting due to a wait join timer expiry event.

When I did a debug capwap error one of the lines associated to all of the APs was....unable to get AP bundled version, using controller version.

Any thoughts on what I am missing?

Post the complete output to the following commands:

1. WLC: sh sysinfo;

2. WLC: sh time;

3. AP: sh version;

4. AP: sh ip interface brief; and

5. Reboot the AP. We want to see the entire boot-up process.

jvasilko · ‎03-24-2017

I have attached the sysinfo, time, and an AP boot sequence, did not have access to the AP (remotely located) to get the AP info you requested, hopefully the AP boot will tell you what you need to know.

*Mar 1 00:03:46.967: %CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP
. Renewing DHCP IP.

Here's the reason: DHCP Option 43 is not configured.

jvasilko · ‎03-24-2017

I used the DNS entry cisco-capwap-controller.x.com as the alias for my controller address. I am seeing them attempt to join the controller, so they know how to get there.

Jerry Lemke · ‎03-24-2017

I didn't see from the APs perspective that it actually discovered the controller. From the controller what does is show under AP join statistics for these APs? Monitor>statistics> AP Join.

You could try to Prime the controller address into the AP using "capwap ap" commands from the AP CLI.

jvasilko · ‎03-24-2017

Each AP show up as 'not joined' and have a reason for unsuccessful attempt as failed to delete database entry.

I would normally prime these with the controller command, but that did not work either. They tried to join, but failed with the response above.

Leo Laohoo · ‎03-24-2017

Cisco IOS Software, C3700 Software (AP3G2-RCVK9W8-M)

Look at the IOS the AP is loading, it is the recovery (aka RCV) image. This means the AP has never seen a controller before.

If the AP has an IP address, enter this enable command: config ap primary- <WLC Name> <WLC Management IP address>

sandjose_cisco · ‎03-27-2017

were you able to get the debug capwap events from the WLC

check if DTLS is getting completed

show dtls connections

There are some cert issues with SHA2 , please have a check

http://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63916.html

jvasilko · ‎03-27-2017

When I checked before, there was a successful DTLS connection being made for the APs. These APs are all brand new 3702i APs trying to connect to a brand new 5520 running 8.2.141.0 code, so I would hope that SHA2 certs are not the problem.

jvasilko · ‎03-27-2017

Found the issue this morning. I checked the licenses and they weren't activated. The GUI showed 1500 AP license, but they weren't accepted. Sort of a silly exercise to accept something that I obviously wanted, but its resolved now so I am good to .

jvasilko · ‎03-27-2017

The APs are trying to connect to the controller, they are getting denied for some reason, and that is the issue. I have entered the command directly on a test AP with the same results. SO the APs have seen the controller, they are just unable to join.

ibneali991 · ‎03-20-2024

Hello brother I am facing same issue. how you resolve this issue before kindly guide me thanks.
