Usage Guidelines

Usage Scenario

The DSCP value is designed to ensure the communication service quality. It is an 8-bit identifier contained in an IP packet header, and identifies service types and priorities.

When network data transmission is stable, PCE Client does not need to change the DSCP value of the data packets sent. When packet loss occurs during data transmission, you can configure a DSCP value for the data packets sent. You can improve the priority of packet transmission to ensure the quality of network data transmission.

Prerequisites

Run the connect-server command to configure a candidate PCE server for the PCE client.

Precautions

The DSCP value of IPv4 packets ranges from 0 to 7.

Example

# Configure a DSCP value for a PCE client.
