an attempt to configure 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, configure the
cable using the cx4-cable-length short command only to avoid any errors.
Note:
15M CX4 active cable is not supported on C-Series and S-series. It is only supported
for S2410 with active end on the device.
