Define Incoming Packet Priorities

You can define the priority of incoming packets by using the priority-map command so that incoming packets are tagged with a defined priority. You can use the map interface command to define the interface.

1. Define the priority for incoming packets on a given interface (0/4 in this example).

   SEFOS# configure terminal 
   SEFOS(config)# priority-map 500 
   SEFOS(config-pri-map)# map interface extreme-ethernet 0/4 in-Priority-type vlanPri in-priority 5 regen-priority 3 
   SEFOS(config-pri-map)# exit 
   SEFOS(config)# exit
   

2. Review the priority map information.

   SEFOS# show priority-map 500
   QoS Priority Map Entries 
   ------------------------ 
   PriorityMapId          : 500 
   IfIndex                : Ex0/4 
   VlanId                 : 0 
   InPriorityType         : VlanPriority 
   InPriority             : 5 
   RegenPriority          : 3 
   InnerRegenPriority     : None
   

   You can use any of the preceding commands to define a packet stream. You must define each traffic stream with an interface. After you define a packet stream, you must map it into a traffic class for QoS management. You do this with the class-map command.
