Defaults medium Mode Interface Command History Version 7.7.1.0 Introduced on S-Series Usage 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: 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. Example Figure 23-2.
