set class-of-service pfc-uplink-group original-dscp to-code-point

The set class-of-service pfc-uplink-group original-dscp to-code-point command modifies the queue priority of hook flow packets that match the PFC uplink port group and the original DSCP value.

The delete class-of-service pfc-uplink-group original-dscp to-code-point command deletes the configuration.

NOTE:

  • This command is supported only on the Trident3-X5 and Trident3-X7 platforms.

  • When configuring or deleting on the Trident3-X5 and Trident3-X7 platforms, the following two commands both need to be configured and submitted in the same commit.

set class-of-service pfc-uplink-group <group-name> original-dscp <origin-value> to-code-point <queue>

set class-of-service pfc-uplink-group <group-name> original-dscp <origin-value> dscp <value>

 

Command Syntax

set class-of-service pfc-uplink-group <group-name> original-dscp <origin-value> to-code-point <queue>

delete class-of-service pfc-uplink-group <group-name> original-dscp <origin-value> to-code-point

 

Parameter

Parameter

Description

pfc-uplink-group <group-name>

Specifies the name of the uplink port group. The value is a string.

original-dscp <origin-value>

Specifies the original DSCP value of the hook flow packets that matches the PFC uplink port group. The value is an integer that ranges from 0 to 63.

to-code-point <queue>

Specifies the adjusted queue priority of hook flow packets that match the PFC uplink port group, ensuring that the hook flow packets are forwarded from the specified queue. The value is an integer that ranges from 0 to 7.

 

Usage Guidelines

For hook flows that match the PFC uplink port group, the queue priority and DSCP value in the packets will be actively adjusted, changing the path of PFC pause frames to prevent PFC pause frames from forming loops.

 

Example

  • Modify the queue priority and DSCP value of hook flow packets that match the PFC uplink port group and the original DSCP value.
