## Map Ingress Traffic to Egress Class

1. Map ingress traffic on a defined interface (`0/5` in this example).

       SEFOS# configure terminal
       SEFOS(config)# queue-map CLASS 3000 interface extreme-ethernet 0/5 queue-id 3
       SEFOS(config)# queue-map CLASS 3001 interface extreme-ethernet 0/5 queue-id 4
       SEFOS(config)# queue-map CLASS 3002 interface extreme-ethernet 0/5 queue-id 5
       SEFOS(config)# queue-map CLASS 3003 interface extreme-ethernet 0/5 queue-id 6
       SEFOS(config)# queue-map CLASS 3004 interface extreme-ethernet 0/5 queue-id 7
       SEFOS(config)# exit

2. Review the queue map entries.

       SEFOS# show queue-map interface extreme-ethernet 0/5

       Ex0/5    3000   none          0               3
       Ex0/5    3001   none          0               4
       Ex0/5    3002   none          0               5

       Ex0/5    3003   none          0               6
       Ex0/5    3004   none          0               7

   Forwarding packets from the same traffic class to the different egress ports is possible, as when the system is configured as a router with more than one interface connecting to other routers. Thus, to guarantee the packet behavior on a different port, you can repeat the steps in the forwarding example (using the `queue`, `scheduler`, and `queue-map` commands) for a different interface.
