6.5 Class-of-Service (CoS) Support

The switch provides two transmit queues on each port, with a weighted fair queuing scheme. This
function can be used to provide independent priorities for various types of data such as real-time video or
voice, and best-effort data.
Priority assignment to a packet in this switch can be accomplished in any of the following ways:
• Priority can be explicitly assigned by end stations which have applications that require a higher priority
than best-effort. This switch utilizes the IEEE 802.1p and 802.1Q tag structure to decide priority
assignments for the received packets.
• A port may be manually configured as high priority. In this case, when any other port receives traffic
from a high-priority port, that traffic is automatically placed in the high-priority output queue.
