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.
