- Silver, 250 points or more
I have two catalyst 4500 model switch, connecting a trunk of fiber. At one end, there is '4510 with SFP (WS-X4516) module' and at another end there is '4510 with GBIC (GLC-SX-MM) module'. But the problem is, our SFP module is getting damaged on regular basis each after 5/6 months. Can anyone guide whether it's the compatibility issue or anything else? What change can prevent this damage?
