Qos Trust (Interface) - Dell PowerConnect 3424 Cli Reference Manual

• cos — Indicates that ingress packets are classified with packet CoS values. Untagged
packets are classified with the default port CoS value.
• dscp — Indicates that ingress packets are classified with packet DSCP values.
Default Configuration

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.
• 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
