Defining Basic QoS Settings

The QoS General Page contains information for enabling Trust on the device.
Packets entering a QoS domain are classified at the edge of the QoS domain.
Command Attributes
• Trust Mode — Selects the trust mode. If a packet's CoS tag and DSCP tag are
mapped to different queues, the Trust mode determines the queue to which the
packet is assigned. The possible field values are:
• None — Sets the Trust mode to none. All packets are sent to the lowest queue.
• CoS — Sets the Trust mode to CoS. Packets are queued based on their CoS
field value.
• DSCP — Sets the Trust mode to CoS. Packets are queued based on their
DSCP tag value.
• Always Rewrite DSCP — Rewrites the packet DSCP tag according to the QoS
DSCP Rewriting configuration. Always Rewrite DSCP can only be checked if the
Trust Mode is set to DSCP.
