Cisco AP 3802 cannot join WLC - aptrace_register_sysproc_fn: duplicate registeration for 'wired'
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 184.108.40.206 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?
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 18:40:55.3865] Waiting for uplink IPv4/IPv6 configuration [*02/23/2018 18:41:08.3887] Resetting wired0, if[02/23/2018 18:41:08.4200] wired0: stopped config down up [02/23/2018 18:41:10.5000] wired0 emac 2: link up [02/23/2018 18:41:10.5600] wired0: link up [02/23/2018 18:41:10.6000] wired0: started [*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
