Cisco AP 3802 cannot join WLC - aptrace_register_sysproc_fn: duplicate registeration for 'wired'

bbcanary73 — Mon, 05 Jul 2021 16:33:08 GMT

Hi,

We have bought some Cisco 3802 Ap's. I connected 1 of the AP's to a switch we have at our office to see if it worked and it did. I read that there has been some bugs with the AP where if you connect it to a 100mbps port it will show you the "aptrace_register_sysproc_fn: duplicate registeration for 'wired'".
I have now set up the antenna up on the right location, but we are using a POE which is 1gbps.

The problem is the same as with 100mbps... I have tried to google it, but so far I don't see any solution.

The WLC is running version 8.5.135.0 which is not the newest. I would love to update the version, but we can't since we also have 1602 AP's in our enviroment, so if we update 1 more version it doesn't support it anymore.

Does anyone have a good solution to make the 3802 AP to work with a POE?

Regards,

Jørgen

Could be this bug

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvi14641/?rfs=iqvred

Symptom:
Access point goes into a boot loop. The switch shows the link as up, but no CDP information.
The AP console shows messages similar to the following:

[*02/23/2018 18:40:50.3857] waiting for POE negotiation to complete
[*02/23/2018 18:40:52.9034] SYS-COND: AP is in critical condition

[*02/23/2018 18:41:10.6537] aptrace_register_sysproc_fn: duplicate registeration for 'wired'

Conditions:
- switch port speed is configured for 100Mbps (or, in some cases, a port configured for 1Gbps may come up in 100Mbps due to cabling)
- AP2802 or 3802 (problem does not affect IOS APs or 1800 series)

Workaround:
Change the switch port speed to 1000M, or use a power injector

I had a similar issue with AIR-2802I unable to obtain an IP address via DHCP and join 3504WLC. Besides changing the software, you could try what I did which was assigning the AP an IP address manually, i.e.

capwap ap ip {ip_addr} {subnet_mask} {default_GW} {dns_srv1} {dns_srv2} {domain}

Ap was able to join WLC afterwards.

Hello all.

I'm getting the same error message described on the subject. This is the first time that happened with me.

So I'm using dell swiches. I got 20 2802i APs connected and working and one of them is with this message.
aptrace_register_sysproc_fn: duplicate registeration for 'wired'

from the swich side I got 100Mbps Half duplex (with autonegotiation on). all the other ports negotiated at 1000Mbps Full Duplex

If I use another 2802i AP in the same switchport it works fine. I got 200x 2802i APs working, only this one with error.

Even though the AP gets connected to the WLC after a while, but still on half duplex mode 100Mbps

If I fix the speed to 1000Mbps in the port configuration, the AP keep the same message. I don't have any power injector in this site to test.

Software version 8.5.140.0 for all APs

Any other hint?

Hey,

Please check the DHCP server settings in the controller.

If the DHCP hint from arunkr doesn't help, RMA the AP, might be broken.

Hi,

I got the same issue on cisco 2802 and assume this is related to a missing configuration on DHCP server.

I was able to solve by adding a default-router to the DHCP scope:

ip dhcp pool MANAGEMENT
SW(dhcp-config)#def
SW(dhcp-config)#default-router 192.168.1.1

Issue was AP looping DHCP client:

Well, I tried with 5 other APs on the same switchport, and all of them work, but not the faulty one.
I will open an RMA.

I solved this problem by investigating the DHCP server. It turns out conflicts on my DHCP server used up all the addresses. The AP was cycling endlessly trying to get an address. Once I cleared up the DHCP server, the AP connected to the controller and progressed as expected.

Keep in mind that this can happen again. This is known issue with Windows DHCP server and bad address. AP’s like the 3702 when unable to find the controller will request a new dhcp address.

Hello everyone,

This is a bit weird.. I got same error message "aptrace_register_sysproc_fn: duplicate registeration for 'wired'". And I also thought it was DHCP server thing.

Actually i got the above error message by using power injector.

But when i connect without power injector AP receives ip from DHCP and hence joined the controller..

do you think faulty power injector might also display this kind of error?

or any other reasons?

AP is AIR-AP2802I-B-K9.

regards,

shrijan

Test it once or twice more. If you can replicate it, then it's very probably the power injector or one of the cables.

This fixed my issue -- thanks!

I had a small setup where I put the APs on the same LAN as the AP Join interface and WLC 9800 acting as a DHCP server for the AP Join interface. I didn't set a default gateway thinking it wasn't necessary since all on same L2 network, but never got past the "Waiting for uplink IPv4 configuration" stage.

I had this problem as well. In my case what ended up being the problem was the DHCP scope was not defined correctly. Verify your DHCP scope is defined on your server and matches the subnet.
