Quality of Service (QoS) Commands
Default Configuration
dscp
Command Mode
Global Configuration mode
User Guidelines
This command can be used only in QoS basic mode.
Packets entering a QoS domain are classified at its edge. 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.
When the system is configured with trust DSCP, the traffic is mapped to the queue
by the DSCP-queue map.
When the system is configured with trust CoS, the traffic is mapped to the queue
by the CoS-queue map.
For an inter-QoS domain boundary, configure the port to the DSCP-trusted state
and apply the DSCP-to-DSCP-mutation map if the DSCP values are different in the
QoS domains.
Example
The following example configures the system to the DSCP trust state.
switchxxxxxx(config)# qos trust dscp

47.30 qos trust (Interface)

Use the qos trust Interface (Ethernet, Port Channel) Configuration mode command
to enable port trust state while the system is in the basic QoS mode. Use the no
form of this command to disable the trust state on each port.
