We have replaced couple of our 2960CPD-8PT-L with C1000-8FP-2G. On the interfaces that are configured as trunk, the "duplex" command isn't available. Can any C1000 user confirm that?  Thanks

Speed and duplex is not supported on SFP ports.

The small form-factor pluggable (SFP) gigabit LH transceiver provides a full-duplex gigabit solution up to 70 km on single-mode fiber.

standardized speeds from 10Mbps up to its maximum supported speed (e.g. a GigE NIC speaks 10, 100, and 1000Mbps), an optical Ethernet module usually support only the specific transmission speed

The duplex can not be changed.

Hope that is clear now.

Thanks,
Jitendra
