Default Ingress User
Priority
See or enter a new 802.1p port transmit priority for frames that are
received (ingress) without priority information in their tag header.
Valid priority values are 0 through 7, with 0 being lowest priority and
7, highest. A port receiving a frame without priority information in its
tag header is assigned a priority according to the priority setting on the
port. For example, if the priority of a port is set to 5, the frames
received through that port without a priority indicated in their tag
header are classified as a priority 5. Default port priority is 1.
Number of Egress
Traffic Classes
See the number of egress traffic classes, or transmit queues, available
for each port. Of the 4 traffic classes (numbered 0 through 3) available,
0 is assigned the lowest priority queue. Traffic classes can map 802.1p
port priorities to transmit queues. For example, if the port priority
queue is set to 3 for those frames with a port priority 7, then those
frames would be transmitted before any frames contained in traffic
classes 2 through 0.
