Every document I find on Cisco's website seems to indicate that the SFP-GE-S is not supported on the 2960 platform. However, I have a customer who is using one in a 2960 connected to a 4506. Does anyone know if this used to be supported, or is currently supported or what?
According to the matrix here -
That SFP isn't supported in the 2960 platform, however it is supported in the ME3400 from IOS 12.2(46)SE. The only difference I can see between the SFP-GE-S and the GLC-SX-MM is DOM (Digital Optical Monitoring):
I assume therefore that either the 2960 supports this module but it isn't documented well or it is being detected as a GLC-SX-MM transceiver.
