show dcb cn cp-mapping

Use this command to display the Congestion Point Identifier (CPID) to index mapping by port.

Syntax

show dcb cn congestion-point [port-string]

Parameters

port-string (Optional) Specifies a congestion point port to display for CPID to index mapping. For a detailed description of possible port-string values, refer to Port String Syntax Used in the CLI in the S-, K-, and 7100 Series Configuration Guide.
cp-id (Optional) Specifies a congestion point ID to display.
stats (Optional) Displays congestion point statistics.

Defaults

If a port or range of ports is not specified, mapping information for all ports displays.

Mode

All command modes.

Usage

A unique CPID displays for each transmit queue on bonding ports. On 40GbE mux ports, four CPIDs map to a single congestion point.

Examples

This example displays congestion point mapping information for ports tg.1.1 through tg.1.3:

System(rw)->show dcb cn cp-mapping tg.1.1-3
CP Identifier            Port        IF Index    CP Index
-----------------------  ----------  ----------  ----------
00-1F-45-A0-6A-47-00-10  tg.1.1      13001       5
