We are having intermittent problems where trunk links error-disable due to ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected error.
So far it has happened on 2950 (12.1(22)EA9) and 2960 (12.2(25)SEE2) switches, with the latter only having one trunk link to the next switch.
We may be running into bug: CSCea46385, with the workaround of removing keepalives from the interfaces. If we do this, how will it affect spanning tree?
Thanks in advance.
