Routed traffic

When you route traffic over the core network, VLANs are not kept separate. The following case
describes QoS design guidelines you can use to provide and maintain high service quality in an
Avaya Ethernet Routing Switch 8800/8600 network.
Routed trusted traffic
When you set the port to core, you assumethat, for all incoming traffic, the QoS setting is properly
marked.All core switch ports simply read and forward packets. The packetsare not re-marked or
reclassifed from the switch. All initial QoSmarkings are performed by the customer device or the
edge devices,such as the 8003 switch or the Business Policy Switch 2000(in this case, the 8003
switch treats ingress traffic as trusted).
The following figure shows the actions performed on three different routed traffic flows (that is VoIP,
video conference, and e-mail) at access and core ports throughout the network.
