Avaya G430 - Priority Queuing

Priority queuing
Priority queuing enables you to queue packets according to the priority of each packet. There
are four levels of priority. The total number of packets in all queues cannot exceed 5000.
You can enable priority queueing on the following interfaces:
• FastEthernet (L2, L2-L3) - when Traffic Shaping is configured
• Dialer (L2, L2-L3)
Priority queueing is disabled by default, since the default and recommended queueing method
is WFVQ.
The high priority queue can be further split into two parts for voice traffic: control packets and
bearer packets. This is called VoIP queueing. When VoIP queuing is enabled, the bearer queue
size is calculated to meet the estimated queueing delay, which is 20 ms by default. You can
re-estimate the queueing delay, which results in a change in the bearer queue size.
