I have a strange behaviour when I connect 2 giga optical interface of 2 cisco 7600 over an SDH link (7600 - ADM ----sdh----ADM - 7600).
I can observe loss of packet even with a simple ping with size 100B...but the misterious is that if I start different parallel sequence of the same ping (ex 10000 pckts)..after the 3rd all works fine (all the 3 ping have loss no more)!!!
Furthermore if I use fastethernet instead of gigibitethernet, all works fine.
Many thanks in advance for your support
