Hi guys,
I was wondering if anyone has tried a S-31DLC20D GBIC in a Cisco 3750 Catalyst and had success.
We are going to be transitioning to Mikrotik HW on this particular switch, but I need a fiber circuit up ASAP and I really don’t want to spend hundreds on a GBIC that’s Cisco only.
Please make sure your switch device does not have proprietary lock for SFP modules, you need to study Cisco documentation.
Cisco products only supports their own SFPs, other SFPs don’t work.
But you may have a look here, maybe it helps: http://www.flexoptix.net
I don’t have a S-31DLC20D to test, but Cisco 3560/3750 switches can support 3rd party SFPs if you enter the following commands:
service unsupported-transceiver
no errdisable detect cause gbic-invalid
The first allows non-Cisco SFPs and the 2nd stops SFPs being put into the err-disable state.
