No AP found on CLI Command show ap summary - CISCO 1850

[JMD31]

Hi I have performed 'clear config' and 'reset system' commands on two access point CISCO 1850 with same result.

After reboot I have done the configuration (administrative account and SSID parameters).

But on both AP, after restart, I can login but the command 'show ap summary' don't find any AP. Typical answer is:

Number of APs.................................... 1

The list of the AP's don't appear

I'm convince that it's a configuration problem but I'm not able to figure out what's wrong.

Firmware version is 8.10.162.0.

Thanks for your help

 - Have a checkup of the mobility express controller configuration using : https://community.cisco.com/t5/networking-knowledge-base/show-the-complete-configuration-without-breaks-pauses-on-cisco/ta-p/3115114#toc-hId-1039672820  ; feed the output into :

I guess you're running Mobility Express on both APs?
Are they both connected to the same network/vlan/subnet with a DHCP server and enough free IP addresses to provide 2 IP addresses for each AP? 
When you're running Mobility Express the AireOS controller (ME WLC) consumes 1 IP address and the the client serving AP component also requires an IP.  The APs can't join the WLC until they an IP address.
So step number 1 - make sure each ME and AP has got an IP address from DHCP and that they can ping each other.

Hi

I have the problem one one AP. The show ap summary returns 0 ap.

(Cisco Controller) >show ap summary

Number of APs.................................... 0

Global AP User Name.............................. elta
Global AP Dot1x User Name........................ Not Configured
Global AP Dot1x EAP Method....................... EAP-FAST

* prefix indicates Cisco Internal AP

However I'm able to enter the apciscoshell console and I found that the wired0 interface is down and unassigned.

(Cisco Controller) >apciscoshell
!!Warning!!: You are entering ap shell. This will stop you from establishing new telnet/SSH/Web sessions to controller.
Also the exsisting sessions will be suspended till you exit the ap shell.
To exit the ap shell, use 'logout'

APD4AD.BD66.5340>show ip interface brief
Interface IP-Address Method Status Protocol Speed Duplex
wired0 unassigned unset down up n/a n/a
wired1 n/a n/a down up n/a n/a

wifi0 n/a n/a administatively down down n/a n/a
wifi1 n/a n/a administatively down down n/a n/a
APD4AD.BD66.5340>

I Tried capwap ap ip command, i I get no error but the interface remains down.

How can I put it up ?

Thanks

On ME WLC: show interface summary
On AP shell - go to enable mode "enable" then "term len 0" and "show log" to see what the log shows.
What's the status of the switch port the AP is connected to?
Do you have a DHCP server providing IPs? (did you read my previous reply?)

Hi,

Sorry for the delay I was out of my office yesterday.

And sorry again I forgot to answer, both EWC and AP have fixe IP address.
I had got the same problem on two separated CISCO 1850. On the first I have resolve the problem with the command capwap ap ip x.x. ... and it works well after reboot. But on the second the capwap command didn't resolve the loss of the AP.

I think the second has a real material probelm, but unfortunatly I don't have more time to lead futher investigations. AS far as one of my two AP is working I will just have a look on the show log and stop there.
Thanks for your help.
