Helo!

I have few controllers and more than 100 ap's. When I connnet ap to the ppoe switch (cat 3560) som ap's detected as ieee pd device and not seen by cdp. This ap's received ip addreses from DHCP and I can ping this device but can not registred this ap's on controller. I saw info that ap's can be broken, but it means that more than 25% of new 1240AG broken from the box.... can somebody help me out please

What is the EXACT model of your switch?

Cisco Catalist 3560  POE IOS 12.2(55)SE8

In DHCP i have:

Vendor classes for 1020 and 1240AG

102 option for each vendor class

dns name

in dns I have record

CISCO-LWAPP-CONTROLLER with  managemen address controller

Cisco Catalist 3560  POE IOS 12.2(55)SE8

Again, let me repeat my question:  What is the EXACT MODEL of your switch? 

Whenever I see "IEEE PD" this means three things:

1.  Your AP is not booting up properly;

2.  You have a faulty cable; or

3.  Your switch is dead. 

I'm trying to determine #2.  The only way to do this is to determine if your switch model can support TDR

My switch do no support TDR.

We try connet new AP's from the box with new patchcord to the switch - no result - same story.  It happens on few switches. For example port 46 work ok - but ports 47-48 - is not

Change the patch cable on both ends and try again.

Strange, ap's get ip and i can ping this ip, but not work. Now I will try to connet it to the switch directly with a new cable. The question is - it should be just cat 5 or 6 cable - nothing else?

Cable should have all four pairs terminated. 

What meant is ap no registred and Cause=Max Retrasmission

we try to attach ap directrly with a short cable, but no sucsess, still ieee pd. switch is working properly. Other ap is detected correctly and registred on controller.

The problem still exist. ap's received dhcp address, the lights on 1020 shows that's all ok but not work !

What is the software version you are running on your WLC ?
