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. |
