SQE would never leave the tranceiver so that's that. Besides, it's not like you have an external AUI transceiver lying around! W/o a cisco router, there's no keepalive (loop replies used by Cisco to make sure the path is OK - electrically speaking) so that rules that out.

Keep in mind that almost all switches will not forward damaged frames, so you need to keep that in mind. I know you're using a tap, but you have to ensure that the tap is in the path reporting the dropped frames. This is obvious, but I just wanted to rule it out. -- Thanks, Hansang _______________________________________________ Wireshark-users mailing list Wireshark-users@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-users
