Routed traffic
If you route traffic over the core network, VLANs are not kept separate.
If you configure the port to core, you assume that, for all incoming traffic, the QoS configuration
is properly marked. All core switch ports simply read and forward packets. The switch does
not re-mark or classify the packets. The customer device or the edge devices perform all initial
QoS markings.
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.
