AP-375 won't join Wireless Manager

Good afternoon all,

I'm trapped into an issue which I'm unable to sort it out.

Our environment has a redundant 7205 Wireless Manager running 8.3.0.1.

I have a bunch of AP-304 and AP-305 that works fine. I had to add additional AP to our env, in particular AP-375 outdoor. I would expect that AP would join WM automatically as other AP has done but it wasn't.

Then I connect to the serial console and forced AP conversion via cmdline specifying CAP mode and WM VRRP ip address.

Then AP download the new firmware and reboots. Once it boots then it stops at:

On WM no AP appears to be provisioned. After 60-70 secs AP reboots to factory image.

 

Does anybody has some suggestions?

 

Thank you

Re: AP-375 won't join Wireless Manager

Thanks for the update on the firmware version running on the mobility controller (8.3.0.1 vs 8.0.3.1). That addresses the first concern.

 

Can you attach the full console log from the AP-375 booting up? Specifically, I'm looking for the part where the AP gets an IP address and then does master discovery to try and find the controller to connect to.

 

The AP-375 will behave a little differently than the AP-300 series, as it is a single image universal image that can run in either Instant or controller based architectures, depending on what it discovers during boot up. Since it appears the AP did discover your mobility controller in order to update code, those boot details will help diagnose further what is going on.

Hi Charlie,

here you will find the full console log captured BEFORE and AFTER the AP conversion to managed AP. It boots the same Wireless Manager Version but stops at # prompt. Then it rebbots automatically to factory after 60-70 secs.

 

Thanks

Thanks for the logs. Is CPSec enabled in this environment, and has the new AP-375 been added to the whitelist so that it can communicate with the controller?

ADP is disabled by uap_controller_less

Re: AP-375 won't join Wireless Manager

Hi Charlie,

yes the CPSec is enabled and the AP is whitelisted. I have tried as well as to disable UAP controller less env but same issue.

I have also captured the datapath table once the AP is booted after conversion.

No way to hook it up. It still reboots.

 

Thank you

Is there anything interesting in the mobility controller's log?

Hi Charlie,

thi is what I captured from system log just after issuing AP converion command and rebooted it.

Re: AP-375 won't join Wireless Manager

There's not enough information from the log entries to show the AP-375 attempting to connect. The datapath output you provided shows the AP sending syslog to the controller (port 514), but there is no PAPI for control plane. The AP and controller are on the same subnet, so unless there's a layer 2 firewall blocking traffic, there should not be anything keeping a whitelisted AP from joining.

 

Two thoughts. The AP-375 is not trying to come up as a mesh point, correct?

 

What is the current license state on your controller? 

 

show ap license-usage

Are there enough valid licenses available for the new AP to join the controller?

Re: AP-375 won't join Wireless Manager

Hi Charlie,

that's exactly our issue. AP won't come as mes point.

What drives me crazy is that I have this issue ONLY with AP-375 (I have 5 of them and no one joins the controller). The behavior is the same: connect to WLC, get latest firmware, reboot and try to connect, then reboot in factory mode. I have already joined several 304 and 305 models with no issues.

 

Below there's my license info:

 

(W11NWLAC01) [mynode] #show ap license-usage

Thank you again for your support.
