Configuration considerations
• Map VoIP traffic with IP precedence 6 or 7 to the pre-defined forwarding class NC, VoD traffic with
IP precedence 4 or 5 to the pre-defined forwarding class EF, VPN traffic with IP precedence 2 or 3
to the pre-defined forwarding class AF, and Internet traffic with IP precedence 0 or 1 to the
pre-defined forwarding class BE.
• Mark VoIP traffic, VoD traffic, VPN traffic, and Internet traffic with a QoS-local ID by source IP
address, and then map VoIP traffic, VoD traffic, VPN traffic, and Internet traffic each to a forwarding
group by QoS-local ID.
• The user groups of the VoIP, VoD, VPN, and Internet services are each assigned to a distinct
forwarding group by instantiation.
Configuration procedure
1. Map different classes of traffic to forwarding classes.
As all traffic is differentiated by IP precedence, you can use the default UP-to-forwarding class
mapping table for mapping different classes of traffic to the pre-defined forwarding classes. To this
end, you must use the qos trust auto command on the incoming ports to specify the trusted priority
type.
