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 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, to avoid errors,
configure 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.
