Usage
Information
This command only works on ports that the system recognizes as CX4 ports. So, for example,
Figure 15-2 shows an attempt to configure an XFP port in an S25P with the command after inserting a
CX4 converter into the port:
Example
Figure 15-2. Example of Unsuccessful CX4 Cable Length Configuration
Figure 15-3 shows a successful CX4 cable length configuration.
Example

For details on using XFP ports with CX4 cables, see your S-Series hardware guide.
long | medium | short
Enter the keyword that matches the cable length to be used at the selected
port:
short = For 1-meter and 3-meter cable lengths
medium = For 5-meter cable length
long = For 10-meter and 15-meter cable lengths
Version 8.3.5.0 Introduced on the S55.
Version 7.7.1.0 Introduced on S-Series
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.
