QoS Baseline Model (11 Class)
Voice: Refers to voice only, and it is marked with EF and limited to 10 percent of link bandwidth in a strict-priority queue.
Interactive Video: Refers to voice and video, and it is marked with AF41 or sometimes as EF and limited to 13 percent of link bandwidth.
Call Signaling: Marked with CS3 and provisioned with a minimum of 2 percent of link bandwidth.
Network Management: Marked with CS2 and provisioned as guaranteed 2 percent of link bandwidth.
Bulk Data: Marked with AF11 and provisioned with 10 percent of link bandwidth with WRED enabled.

Voice → EF (Expedited Forwarding)
Interactive Video → AF41
Bulk Data → AF11
Call-Signaling → AF31/CS3
Network Management → CS2
