Has anyone experienced a situation where GBIC occasionally does not transmit properly with required power? I had a WS-G5486 GBIC in WS-X4306-GB module connected to a SFP in another switch and all of the sudden link started to flap with 4-6min intervals. It had been stable for years. Rx power at the SFP end was very low(SFP had a DOM support). I replaced the GBIC with another one(link came up instantly and become stable) and tested the problematic GBIC in another switch(same model and module) and GBIC transmits with nominal power(-6dBm) and links with another SFP just fine. What bothers me the most is that in the second switch the problematic GBIC seems to works as good as ever. Any experience with similar occasions?
