3.12 QoS Priority Queue Management

Quality of Service (QoS) Priority Queue is a feature that allows the switch to prioritize packets, thereby ensuring that high-priority traffic is handled before low-priority traffic when there is congestion on the network. This can improve network performance and bandwidth utilization on your network.

You can configure four traffic priorities by defining filters, based on packet characteristics, that cause the switch to place traffic into one of these four queues; the queue with the highest priority is serviced first until it is empty, then the lower queues are serviced in sequence.

Defining the Priority List

A priority list contains the definitions for a set of priority queues. The priority list specifies which queue a packet will be placed in. In order to perform queuing using a priority list, you must assign the list to a protocol or ingress port. The same priority list can be applied to multiple port numbers.

To define a priority list, perform the tasks described in the following section.

Assigning Packets to Priority Queues

Assign packets to priority queues based on one of the following qualities:

Protocol type

Interface where the packets enter the switch (Ingress port)

You can specify multiple assignment rules. The priority-list commands are read in order of appearance until a matching protocol or interface type is found. When a match is found, the packet is assigned to the appropriate queue and the search ends. Packets that do not match other assignment rules are assigned to the default queue.

Type o in the Configuration Menu to access the QoS Priority Management Menu. Type i in the QoS Priority Queue Management Menu to set a priority list. Follow the prompts to configure the list.
