I'm cascading two 2950 Switches using a GBIC module on each of the switches.However one of the devices reports the error:-
ETHCNTR-3-LOOP_BACK_DETECTED:, keepalive packet Loop-back detected on GigabitEthernet0/1 . The port
is forced to link down.
I have no intention of looping back anything and neither am I using a Balun cable.
What am I missing guys?

could be due to damge hardware or software. try to reload both switches and check with an other switch.

Thanks for your response.Strange thing is;after connecting the two switches,the link is established for sometime after which the LED goes off and the error message is displayed.
