I have an Avaya 4524GT routing switch, which has some fibre ports and some ordinary ethernet ports. I want to internally bridge one particular ethernet port to one particular fibre port, so that the device effectively works as a fibre to ether adapter. How does one do this?
You connect both circuits, ensure that thy are linked up properly, then put them in the same VLAN.
Responding to your comment below, this is something that a switch does not do. It actually sounds like all you want is a media converter, which can be had for very cheap.
