Command Modes INTERFACE
Command History
Version 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.
