Hi all together!
I have abnormal stattistic of runts errors on ethernet of C3750 (both GE MM, FE UTP) in case I connected PIX firewall ports in trunk mode. LED on C3750 port blink yellow. All other errors counters in order. Total statistic is 1 runts per 2-3 totoal pockets.
(I mean GE ports, than I use PIX 535 with MM optic connection, FE - PIX 525 with ordinary UTP connetctions. Some fact - then I changed "mode auto" on FE ports C3750 to fixed value, statistic RUNTS|TotalPackets changed from 1/1 òî 1/3)
At the same time i havn't problem with throughtput or interface resets.
What does it matter?
