port-cable-type-modify

The SerDes (serializer/deserializer) link in switch ports have several associated Signal Integrity (SI) parameters that help in shaping the output into a clean and well-defined signal based on the transmission line characteristics of the signal traces. This output shaping is used to cancel-out factors such as reflection and signal attenuation and enables the receiver to get a clean and well-defined signal. Collectively, these SI parameters are also known as pre-emphasis settings.

You can modify the pre-emphasis (Signal Integrity) settings for specified ports, by overriding the default settings. 

Syntax   port-cable-type-modify

port port-list

Specify the list of ports you want to associate with the cable type.

type optical|dac

Specify the port cable assembly type from one of the options.

cable-sub-type default|ca-n|ca-l|ca-s

Specify the port cable assembly type from one of the options. Note that this optional parameter is applicable only for DAC cable types.

Note: The cable sub type (N, L, or S) is a hardware specific parameter based on the material used by the cable manufacturer. Hence, you must consult the vendor specification to identify the cable assembly type before configuring this parameter.

Defaults   None

Access   Network Administrator

History   Command introduced in version 6.0.0.

Usage   Use this command to associate a cable type with ports.

Examples  To modify the cable type of port 1 to optical, use the command:

CLI network-admin@switch >  port-cable-type-modify port 1 type optical
