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.

Syntax   port-cable-type-show

port port-list

Specify the list of ports to be displayed.

type optical|dac

Specify the cable type to be displayed.

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 display pre-emphasis settings.

Examples  To display the pre-emphasis settings on switch1, use the command:

CLI (network-admin@switch)1 >  port-cable-type-show

switch  port  type     cable-sub-type

------- ----- -------- --------------

switch1 none  dac      ca-s

switch1 none  dac      ca-l

switch1 none  dac      ca-n

switch1 1-125 dac      default

switch1 none  optical  default
