I have two Cisco Catalyst 2960G switches that I am trying to trunk together.
Each switch has a SFP transciever module plugged into the gi0/24 GBIC port. My setup is like this:
switch1----media converter******media converter-----switch2
- is LC to ST fiber
* is cat5e STP straight through cable
The only reason we are using the media converters is because we don't have any LC to LC fiber. Media converters both state that links are active (flashing lights), but when I do a "show cdp neighbors" on either switch, nothing shows up. The interfaces on both switches show as (notconnect). Trunk ports ARE properly configured to trunk..
Anybody have any ideas? Help would be greatly appreciated.
That would very likely be your issue then. SFPs are typically gigabit only. Fiber transceivers from cisco are pretty much either 100base FX or 1000base FX.
To prove your configuration you'd be better off duplicating the trunk config on a copper port and using a crossover cable to verify.
This is why you couldn't hard-set the port speed. It's already hard-set at gigabit. What is the model of SFP being used?
