Command History
Version Description
7.7.1.0 Introduced on the S-Series.
Usage Information This command only works on ports that the system recognizes as CX4 ports. The show interfaces
command shown in the Example below describes an attempt to congure an XFP port in an S25P with the
command after inserting a CX4 converter into the port.
NOTE: When using a long CX4 cable between the C-Series and the S-Series, to avoid errors,
congure the cable using the cx4-cable-length short command only.
NOTE: The 15M CX4 active cable is not supported on the C-Series and S-series. It is only
supported for S2410 with active end on the device.
NOTE: For information about using XFP ports with CX4 cables, refer to your S-Series hardware
guide.
