Issue with AP 3702i, AP not registered in Flex 7500

[Daniel Alejandro Castro Henriquez]

Hi

My problem is this , I have several Access Points 3702i , which are seteados with Static IP , which were previously configured . When connected to the network , they are not able to register with the WLC Flex 7500, the AP reachable from the WLC for ping , but still not recorded.

I connected to the network, I connect the console to the AP and I reconfigure the AP two or three times, until it is able to register.

Anyone know if this happens over a Bug or a series of equipment failures that come with ????

The Access Point throws typical logs trying to connect to the WLC , try enocntrar a DHCP and restarted , despite having a Static ip and is reachable from the WLC .

Greetings and esperi someone can answer .

What code running on your 7500 ? 3700 require 7.6.100.x or above

If possible attach the console output of the AP while this issue is happening. That will tell us reason for the failures

Version WLC 7.6.120.0

the problem only happens with AP 3702i serial number FCWxxxxx

what if you configure WLC information statically on AP,

LAP#ap capwap primary-base <wlc_name> <wlc_mgt_ip>

Would that make AP register ?

Anyway suggest to move onto 7.6.130.0 as it has lot of bug fixed that are in 7.6.120.0

There are a couple of bugs on the 3700s with latest 15.3+ recovery image releases related to problems with DHCP and DNS discovery.  Also, which discovery method are your APs using to identify your WLC's management IP address?

Optionally, try the following...

ap#debug capwap console cli
ap#test capwap controller ip x.x.x.x

or

ap#capwap ap primay-base WLCNAME WLCIPADDRESS
