Consider this topology GSR - 3750 --(GE over 4xVC4) - NSE100 - NSE100 --(GE over 4xVC4) -- 3550 - GSRThis should have been Nortel GBE, not Lucent my bad.
My first best guess was right, it was lucent system after all. We've now solved the issue, problem is in GBE card in Lucent in hardware revision S1:7, which is broken by design. S1:3, S1:6 work and we should be able to test S1:8 soon, but we expect it to work also. Symptoms were that it flipped bits (but not randomly, just couldn't figure out why certain places saw bit flips) and calculated new, correct CRC to the ethernet frame, after it had flipped bit. -- ++ytti
