Even i have heard that, 3rd party SFPs does not work on the Cisco switches. The port is shutdown, when you insert a GBIC other than Cisco SFP.

Re: compatibility about SFP

Cisco doesn't support anything but Cisco-branded GBICs and SFPs.

On some of the GBICs (1000base-T and DWDM), and all of the SFPs, they check for a special ID in the GBIC/SFP, and if it isn't Cisco-branded, it won't work.
