Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

IgorFi — Mon, 05 Jul 2021 16:02:38 GMT

Ho Folks. I'm doing a degree work and I have some gear here to make some tests, but failing...

I bought a Cisco AIR-LAP1142N-E-K9 on ebay and using evaluation version of vWLC. I have already tried two various versions of vWLC: Air CTVM-7-3-101-0 and CTVM-K9-8-0-152-0.

They have same problem. The wWLC actually can see the LAP, but it tells Status "Not Joined".

It sees its IP address (but not MAC). The can ping each other. The vWLC evaluation is activated.

So see the same thing:

So tired, i tried so many offers.

This some version screenshots:

Some screens from the vWLC:

I don't know if this is enough, The time i set everywhere.

Also, I said, the vWLC can see the LAP:

Could you help me with that? Thank yo.

Post the complete output to the following vWLC commands:
1. sh sysinfo;
2. sh time
I don't see any signs the AP knows the WLC details via DHCP Option 43.

Hi Leo! Thank you for response.

I have installed the AIR-CTVM-K9-8-0-152.0 again.

Here is the information requested:

1) sh sysinfo

2) Sh time:

Interfaces:

And this is fro the LAP:

And this is how Devices are connected:

vWLC is running on VMware Workstation 14. Two network interfaces are selected in VMware, both are Bridged to Host Ethernet Gigabit interface.

Host is wired to the home router (SkyHub3).

Cisco LAP is wired to the Homer router and there is a PoE injector between them.

USB to console cable is wired to the LAP.

Home router ip 192.168.0.1

Settings that I put when installed the vWLC on Workstation:

Service interface IP Address configuration: STATIC

Service interface IP address: 10.10.10.1 255.255.255.0

Management interface IP address: 192.168.0.55

Management interface default router: 192.168.0.1

Management Interface DHCP Server IP address 192.168.0.1

Virtual gateway IP address: 1.1.1.1

Configure NTP server now: NO

Configure system time now: YES

I'm not sure what else to post.

IgorFi — Tue, 28 Aug 2018 12:11:35 GMT

Hi Leo.

I just configured the NTP on the vWLC GUI. But still the same thing.

As you see, I chose my Home router ip as NTP server.

Also, I hope that is not the reason:

This will be a problem for wireless connection, but shouldn't prevent the LAP from joying when wired.

Leo Laohoo — Tue, 28 Aug 2018 12:31:37 GMT

Did you activate the AP license?
Maybe the vWLC doesn't have enough license to support the AP numbers?

Check https://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63942.html

It's also possible that the certificate on the 1142 was somehow corrupted. Can happen when doing the Autonomous -> LWAP conversion not correctly.

You tried to factory reset the AP?

Re: Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

IgorFi — Tue, 28 Aug 2018 17:07:55 GMT

The evaluation version says 200 aps. I have only one LAP.

Re: Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

IgorFi — Tue, 28 Aug 2018 17:16:22 GMT

Hi Patorbeli. Yes, I did the factory reset a few times. Taking the ethernet cable out, then pressing the button, then putting the cable back. The light started flashing blue. Then the terminal shows how the LAP loading. So frustrated, as I bought it on eBay 2 months ago and now need to finish the uni degree project in three weeks. Maybe the LAP firmware is outdated? Where i can see it? Is it feasible to update the LAP firmware without joining the vWLC? Is it easy process? I didn't find any commands related to an update on the LAP.

I don't think the field notice applies because the age of the AP is only 8 years old.

Re: Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

patoberli — Wed, 29 Aug 2018 07:01:26 GMT

You're right. On the first screenshot it looks like the AP is running on the recovery image.
@IgorFi, can you please attach the full boot log of the AP? It seems it's missing an image.
Also check this here for a similar case (with a different AP model): https://community.cisco.com/t5/wireless-and-mobility/wlc-5508-7-6-100-0-ap-invalidates-primary-backup-image-after/td-p/2369541
I don't remember anymore if it first attaches to the WLC or if it first tries to update the image anymore.

Oh and unrelated to this issue, don't use 1.1.1.1 as the virtual-interface address. This address is now being used in the internet and Chrome actually blocks the access if you use a guest portal on that address. Use a 10.x.x.x address.

Re: Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

IgorFi — Wed, 29 Aug 2018 12:13:48 GMT

Guys, thanks for help so far. Hare are some screen shoots upon booting the LAP. If this is what you asked me. I see only one image "rcv".

Re: Cisco AIR-LAP1142N-E-K9 cannot join the vWLC.....

patoberli — Wed, 29 Aug 2018 13:28:42 GMT

You miss the next ~30 lines of log file, the important ones 🙂 Next it should try to connect to the WLC and do a software upgrade (which either fails because of the certificate issue, or some other problem).

If you connect via console, you could also copy&paste the log, instead of screenshots. That would be a little bit easier to read.
One the AP is booted and you waited some 3 more minutes, can you login to it and post the output of the 'dir' command?

Leo Laohoo — Wed, 29 Aug 2018 22:22:23 GMT

Go to the vWLC and enter the command "sh ap join stats summary all". Look for the MAC address of the AP.
Then issue the command "sh ap join stats detail <AP MAC address>". Post the entire output (don't use screenshots).

patoberli — Thu, 30 Aug 2018 07:02:49 GMT

Under Management - HTTP-HTTPS what is the expiry date of that certificate? Asking because this could maybe have an effect on the WLC DTLS certificate. If this certificate was generated before the correct time was configured on the WLC, it might already be expired. In that case, you need re re-generate it and reboot the vWLC.

No worries patoberli, thank you for help.

I'm wondering if the issue is related to another issue I'm having right now. When I'm trying to access the Home router page, I get Windows Internet Information Services Page:

I have disabled IIS feature, but still redirected to this page.
