Where does the Cisco V-Edge Router perform QOS traffic classification?

While QoS policies can be associated with VPNs, the actual packet classification occurs at the interface level, not at the abstract VPN level.

'Per VEdge' is too general; QoS operations are specific to interfaces and applied policies.

Egress interfaces are typically where queuing, shaping, and scheduling actions are performed based on the classification that occurred at the ingress interface.

QoS classification is applied at the ingress interface of the WAN Edge router, immediately upon receiving packets, to identify and mark them according to defined policies for subsequent queuing, shaping, and scheduling throughout the forwarding path.
