4000 Router Series ACL and QoS Configuration Guide

• Configuring priority trust mode—In this approach, you can configure a port to look up a certain

trusted priority type (802.1p, for example) in incoming packets in the priority maps and map the

trusted priority to the target priority types and values.

• Changing port priority—If no packet priority is trusted, the port priority of the incoming port is used.

By changing the port priority of a port, you change the priority of the incoming packets on the port.

To configure priority mapping, perform the following tasks:

Configuring a port to trust packet priority for priority

mapping

NOTE:

This feature is supported only on routers installed with Layer 2 Ethernet switching modules. For information

about interface modules, see

HP MSR Router Series Interface Module Guide

You can configure the device to trust a particular priority field carried in packets for priority mapping on

ports or globally.

When you configure the trusted packet priority type on an interface, use the following available
