R2511-HP MSR Router Series ACL and QoS Configuration Guide(V5)

In this approach, you can configure a port to look up a certain priority, 802.1p for example, in
incoming packets, in the priority mapping tables. If no packet priority is trusted, the port priority of
the incoming port is used.
• Changing port priority.
By default, all ports are assigned the port priority of zero. By changing the port priority of a port,
you change the priority of the incoming packets on the port.
Perform these tasks to configure priority mapping:
Task Remarks
Configuring a priority mapping table Optional.
Configuring a port to trust packet priority for priority mapping Optional.
Changing the port priority of an interface Optional.
