Syntax
qos trust {cos | dscp}
no qos trust
Parameters
•
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
CoS is the default trust mode.
Command Mode
Global Configuration mode
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
