80-Series QoS
Example
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.
