Configuring Queue Priorities
Use the Priority Configuration page to specify which data packets have
greater precedence when traffic is buffered in the switch due to congestion.
This switch has two priority queues for each port. Data packets in a port’s
high-priority queue is transmitted before those in the lower-priority queue.
You can map the frame priority tags (i.e., 0 - 7) to the high or low priority
queues, and also set the method used to process priority traffic (i.e., first-in
first-out, all high before low, or weighted round-robin).
Field Attributes
•
Queue Assignment
– The default priority levels are assigned
according to recommendations in the IEEE 802.1p standard. However,
you can map the priority levels to the switch’s output queues in any way
that benefits application traffic for your own network. (Range: Low,
High; Default: Low - Priority Tags 0-3, High - Priority Tags 4-7)
• High/Low Queue Service Ratio
(H:L)
-
#:#
(Weighted Round Robin) – Sets the preference given to packets
in the high-priority queue. This specifies the number of high-priority
packets sent before one low-priority packet is sent. You can set this
field to 1:1 to disable priority service. (Range: 1:1 - 7:1; Default: 2)
-
FIFO
(First Come First Served) – Packets are processed first-in
first-out.
-
H->L
(All High before Low) – All packets in the high-priority queue
are processed before any packets in the low-priority queue.
