I try to connect with fiber two switches. One Cisco Catalyst 3750 with 12 SFP's and a Enterasys Matrix with several modules.
I install a 1000Base LX GBIC in the CIsco, an i connect it to an SC type connector in the Matrix switch, but they don't link. I try to connect the catalyst 3750 to another catalyst 500 and they link perfectly, so there is no problem with fiber optic cable.
Is there any special configuration needed in the CIsco, or in the Matrix?
What could be the problem?
