C1000 duplex command

[cokho]

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.

[Jitendra Kumar]

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.
