Hi All,
While doing my practice labs, I was facing the below 2 error message and the interface will be err-disabled.
ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on <INTERFCAE>
PM-4-ERR_DISABLE: l2ptguard error detected
I googled the above messages and got directed to a cisco link which explains the first error message to be a condition due to balun cable incorrectly connected to ports and I didnt get any useful info about the second one
Can some one please let me know if it is any config issue?. I was practicing Lab 20 in IEWB 4.1 Volume 2
As a workaround, I disabled the error check and continued the lab.
Regards,
Nagendra
