Priority; Port Priority Configuration - Alcatel OmniStack 8008 User Manual

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:
