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.
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.
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.
Console(config)# qos trust dscp
