User Guidelines

Packets entering a quality of service (QoS) domain are classified at the edge of the QoS domain. When 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 device in the domain.

A switch port on an inter-QoS domain boundary can be configured to the DSCP trust state, and, if the DSCP values are different between the QoS domains, the DSCP to DSCP mutation map can be applied.

Use this command to specify whether the port is trusted and which fields of the packet to use to classify traffic.

When the system is configured as trust DSCP, traffic is mapped to a queue according to the DSCP-queue map.

Example

The following example configures the system to the DSCP trust state.

Console(config)# qos trust dscp

qos trust (Interface)

The qos trust Interface Configuration (Ethernet, port-channel) mode command enables each port trust state while the system is in the basic QoS mode. To disable the trust state on each port, use the no form of this command.

Syntax

qos trust

no qos trust

Default Configuration

qos trust is enabled on each port when the system is in basic mode.
