You want to assign a priority of 5 to a VoIP flow that is destined to an IP

600 phone switch. You then want the switch to use the CBWFQ queue-

servicing algorithm to forward frames from queue 5. The IP 600 phone

switch is connected to an Avaya P882 Multiservice switch on port 5.5.

1. You set up an ACL rule that associates a priority of 5 with the destination

IP address of the VoIP flow. (VoIP traffic cannot tolerate latency or

frame loss, so it needs a high priority to ensure its timely delivery.)

* Note: Priority 5 serves as an example only. Actual

implementations may vary.

2. You enable CBWFQ for queue 5 on port 5.5.

3. The switch assigns a priority of 5 to the ingress VoIP packets and

forwards them through ingress queue 5 to the egress port.

4. The switch stores the VoIP packets in egress queue 5 on port 5.5. (The

switch places packets in the queue that matches their priority.)

5. The switch uses the CBWFQ algorithm to remove the packets from

queue 5 and forward them to the IP 600 phone switch.
