Information
This command only works on ports that the system recognizes as CX4 ports. The figure
below shows an attempt to configure an XFP port in an S25P with the command after
inserting a CX4 converter into the port:
Example
FTOS#show interfaces tengigabitethernet 0/26 | grep "XFP type"
Pluggable media present, XFP type is 10GBASE-CX4
FTOS(conf-if-te-0/26)#cx4-cable-length short
% Error: Unsupported command.
FTOS(conf-if-te-0/26)#cx4-cable-length medium
% Error: Unsupported command.

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

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.
