Configuring priority mapping
Overview
When a packet arrives, a device assigns a set of QoS priority parameters to the packet based on a
certain priority field carried in the packet or the port priority of the incoming port, depending on your
configuration. This process is called "priority mapping". During this process, the device may modify the
priority of the packet depending on device status. The set of QoS priority parameters decides the
scheduling priority and forwarding priority of the packet.
The device provides various types of priority mapping tables, or rather, priority mappings. By looking up
a priority mapping table, the device decides which priority value is to assign to a packet for subsequent
packet processing.
You can configure priority mapping by configuring trusting packet priority or trusting port priority.
• If packet priority is trusted, the device uses the specified priority field of the incoming packet to look
up the priority mapping tables for the set of QoS priority parameters to assign to the packet. Note
that, if a received packet does not carry the specified priority field, the device uses the port priority
to look up the priority mapping tables for the set of QoS priority parameters to assign to the packet.
• If port priority is trusted, the device uses the port priority rather than packet priority to look up the
priority mapping tables for the set of QoS priority parameters to assign to the packet.
Configuration procedure
1. Select QoS > Trust Mode from the navigation tree to enter the priority trust mode configuration
page.
