Use this command to display the Congestion Point Identifier (CPID) to index mapping by port.
| 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. |
| -interesting | (Optional) Displays only statistics of ports that transmitted congestion notification messages. |
If a port or range of ports is not specified, mapping information for all ports displays.
All command modes.
A unique CPID displays for each transmit queue on bonding ports. On 40GbE mux ports, four CPIDs map to a single congestion point.
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 00-1F-45-A0-6A-47-00-14 tg.1.2 13002 5 00-1F-45-A0-6A-47-00-18 tg.1.3 13003 5
show dcb cn congestion-point Output Details provides an explanation of the command output.
