New Install 2504-K9 & 1602I-E-K9 Radio down

Answered Question
Jan 11th, 2014
User Badges:

Searched forums and blogs, this has got me stumped and I hope someone can help.


I have a new install, seems the AP can find the controller but the radios will not come up.


The AP is directly connected to the controller by a 70m cable run.


Checked the regulatory domain, all UK.


Controller AIR-CT2504-K9

Software Version

7.4.100.0


AP AIR-CAP1602I-E-K9


I’ve attached when I get from a console cable during an AP boot, but my research have been around the following:


*Jan 10 14:07:08.495: %CAPWAP-3-ERRORLOG: Invalid event 10 & state 5 combination.

*Jan 10 14:07:08.495: %CAPWAP-3-ERRORLOG: CAPWAP SM handler: Failed to process message type 10 state 5.

*Jan 10 14:07:08.495: %CAPWAP-3-ERRORLOG: Failed to handle capwap control message from controller

*Jan 10 14:07:08.495: %CAPWAP-3-ERRORLOG: Failed to process encrypted capwap packet from 10.10.10.20

*Jan 10 14:07:08.827: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to administratively down


Any help greatly appreciated.


Thanks.

You can enable the 802.11a radios from there.

State of 802.11b Network......................... Disabled

State of 802.11a Network......................... Disabled

Uhhhhhh ... This is the main reason why your radios are down.  I found it in the first file, the "sh sysinfo".

I have a new install, seems the AP can find the controller but the radios will not come up.

Radios will always be down because the AP can't find the controller.  Once the AP joins the controller the radios will go up.

The AP is directly connected to the controller by a 70m cable run.

This better be a temporary solution.  This method is not recommended by Cisco.


Can you please post the following output:


1.  WLC:  sh sysinfo;

2.  AP:  sh version;

3.  AP:  sh ip interface brief; and

4.  AP:  sh inventory

You should also post more of the output from the console of the AP. That ca tell us more than what you have provided.

Thanks Leo - Didn’t realise that I had to explicitly enable the radios.


So for others new to Cisco Wireless: via the controller, Wireless, 802.11b/g/n, network > enable in the general settings.
