port-cable-type-show
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 display the pre-emphasis (Signal Integrity) settings for specified ports by using this command.

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. |
