Priority
IEEE 802.1p defines up to 8 separate traffic classes. This switch
supports Quality of Service (QoS) by using two priority queues, with
weighted fair queuing for each port. You can use the Priority menu to
configure the default priority for each port, or to display the mapping
for the traffic classes as described in the following sections.
Port Priority Configuration
The default priority for all ingress ports is zero. Therefore, any
inbound frames that do not have priority tags will be placed in the
low priority output queue. Default priority is only used to determine
the output queue for the current port; no priority tag is actually added
to the frame. You can use the Port Priority Configuration screen to
adjust default priority for any port as shown below:
Parameter
Port
Default Ingress
User Priority
Number of Egress
Traffic Classes
3-34
Description
Numeric identifier for switch port.
Default priority can be set to any value from 0-7,
where 0-3 specifies the low priority queue and 4-7
specifies the high priority queue.
Indicates that this switch supports two priority
output queues.
