AP 1262 don´t negotiate with Gig Interface

Question

Hi !!
I have new 1262 APs, this have Gig Interface, when I connect the AP in my 6500 with PoE Gig Interface, the AP turn on, but the interface never get up.
I need to change the speed to 100 in the 6500 switch port, when I do this, the interface become UP.
This is the model of the card  WS-X6148A-GE-45AF
This is the Switch IOS  s3223-ipservicesk9_wan-mz.122-18.SXF11.bin
The controller is 5500 version 7.2
This is the interface config:
interface GigabitEthernet4/36
switchport
switchport access vlan 308
switchport mode access
switchport port-security
switchport port-security maximum 5
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity

Yes I do.  ALL the time.
This is caused by a fault in your cable.  Pair D of your cable controls GigabitEthernet and it could be the fault.  There's one way of testing and it would mean running a TDR from the 6500.    Here are the process:
1.  Command:  test cable tdr int Gi4/36;
2.  Wait for 61 seconds (Yes, it takes THAT long when dealing with 4500/6500 line cards);
3.  Command:  sh  cable tdr int Gi4/36;
4.  Please post the output.
