In recent times we have had a high number of Gig ports on our 5505's sup 3 cards, running up errors (you see runts and giants on the far end) and eventually going faulty where even getting a link light up is an effort. It doesn't seem to be version related - we've tried 5.5(4b),(12)and now (12a)- all up 4 failures in 3 months. The weird thing is - if I reset the chassis, the errors disappear for a few days and then gradually increase to the point where the link is almost unusable. We've got spares and CISCO TAC swap them for us...but is anyone else getting similar problems?
