5.17.8 qos trust (Global)

The qos trust global configuration command can be used in basic mode to configure the system to "trust" state. To return to the default state, use the no form of this command.

Syntax

qos trust {cos dscp tcp-udp-port}}

no qos trust

ƒcos — Classifies ingress packets with the packet CoS values. For untagged packets, the port default CoS is used.

ƒdscp — Classifies ingress packets with the packet DSCP values.

ƒtcp-udp-port— Classifies ingress packets with the packet destination port values.

Default Configuration

If the system is in basic mode then CoS is the default trust mode.

Command Mode

Global Configuration mode

User Guidelines

This command can be used only in QoS basic mode.

Packets entering a quality of service (QoS) domain are classified at the edge of the QoS domain. When the packets are classified at the edge, the switch port within the QoS domain can be configured to one of the trusted states because there is no need to classify the packets at every switch within the domain.

Use this command to specify whether the port is trusted and which fields of the packet to use to classify traffic. DSCP value 0-7 8-15 16-23 24-31 32-39 40-47 48-56 57-63

Queue-ID 1 2 3 4 5 6 7 8

For an inter-QoS domain boundary, the port can be configured to the DSCP-trusted state and apply the DSCP-to-DSCP-mutation map, if the DSCP values are different between the QoS domains.
