Hi all
I've a problem with a 1562I that wont join my WLC. I've read a few threads in the Cisco community, describing the same problem, but the solutions doesn't work for me.
Info about my installation:
- Cisco WLC 8540 - software: 8.3.135.0 - 2K+ AP's
- Around 10 different AP models, from 1042's to 2802's (Yes, I know. I should kick out the old models, but you know - economy!)
- 25 Cisco 1562I - running and working
- 1 Cisco 1562I - not working - error message shown in title.
It seems that the AP has been connected and configured once, but when installed at location, it couldn't join WLC. I have recieved it at my office, and is extracting info.
AP is running 8.3.135.0, with 8.5.131.0 as backup boot image. I've tried to switch the boot image with config boot path 1|2 , but with no change.
Solutions from other threads, including adding the AP MAC-address to the "AP Authorization List", doesn't work. Neither does the commands to be used in CLI config ap mode local|flexconnect, can't be used. It seems that those commands doesn't exist on the AP. If I type:
AP70B3.1706.B028#config ap ?
client-trace Configure Client Trace
...then I dont' have the options mentioned in other threads.
Output from show configuration on AP:

Does anyone have suggestions about what to do? RMA (well, I like to solve the problems myself - also to learn)

Try and flash the AP with a newer version code, since you only experiencing this with one 1562 while the other 1562 series are fine I would give that a try as the message you are receiving is related to a software bug. The link below will show you the software versions that are known fixed releases.

Hi Jurgens
I've considered doing just that, but with no change when I switch between primary and backup image, I haven't put much energy in flashing with new code. I did however, try to enter the "u-boot", but haven't yet found a guide to flash. I've only tried to recover image on older AP's through rommon. Can you provide a link or guide to flash though u-boot?

paste the output of these commands
From AP: sh version
From WLC: sh sysinfo

from the AP try this command before using the other commands from the other threads:
debug capwap client cli
Other option would be downloading the AP image from Cisco.com and uploading it via TFTP to the AP

Hi Leo and Haydn
@Haydn Andrews: The command you refer to, isn't accepted on the AP. I can get to debug capwap client, but cli isn't accepted.
AP70B3.1706.B028#debug capwap client
avc CAPWAP client AVC
detail CAPWAP detail
efficient-upgrade Smart image download debugging
error CAPWAP error
events CAPWAP events
flexconnect CAPWAP flexconnect mode event
info CAPWAP info
keepalive CAPWAP keepalive
payload CAPWAP payload
pmtu CAPWAP Path MTU debugging
qos CAPWAP qos
reassembly CAPWAP reassembly
security CAPWAP security
@Leo Laohoo: Check attached log, created with the show logging comand. The show logs doesn't work either.

Raise a TAC Case. I suspect this is CSCvf71074.

Hi guys
Thanks for all your replies.
Our Cisco Partner has advised us to RMA the AP. The time spend on creating a case with TAC, isn't worth it.
Best regards
