Problem with RAP3.



I`ve got a RAP3 that i have connected to a cisco 3560 switch, when i connect it to the switch the port goes into shutdown within a few moments, 


In the log on the switch i am getting the following information


Feb 12 09:34:10.734 gmt: %ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on FastEthernet0/11.
Feb 12 09:34:10.734 gmt: %PM-4-ERR_DISABLE: loopback error detected on Fa0/11, putting Fa0/11 in err-disable state
Feb 12 09:34:11.757 gmt: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/11, changed state to down


Anyone got any idea what can be wrong here?

Re: Problem with RAP3.


Disable keepalives by using the no keepalive interface command. This

will prevent the port from being errdisabled,
