Configuring A Port To Trust Packet Priority For Priority Mapping; Changing The Port Priority Of An Interface; Displaying And Maintaining Priority Mapping - HP MSR4080 Configuration Manual

Configuring a port to trust packet priority for priority
mapping
This feature is supported only on routers installed with Layer 2 switching modules. For information about
interface modules, see HP MSR Series Routers Interface Module Manual.
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
keywords:
dot1p—Uses the 802.1p priority of received packets for mapping.
•
dscp—Uses the DSCP precedence of received IP packets for mapping.
•
To configure the trusted packet priority type on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the trusted
packet priority type.

Changing the port priority of an interface

If an interface does not trust any packet priority, the device uses its port priority to look for the set of
priority parameters for the incoming packets. By changing port priority, you can prioritize traffic received
on different interfaces.
To change the port priority of an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Set the port priority of
the interface.

Displaying and maintaining priority mapping

Execute display commands in any view.
