Displays whether Class of Service (CoS) is enabled or disabled on Layer 2
Switching Modules; shows how the eight possible priority values are
assigned (or, if CoS is disabled, how they were last assigned) to the two
queues; and shows the rate limit that exists on the high priority queue
(queue 1).
Valid Minimum Abbreviation
b c s
Important Considerations
By default, CoS is enabled and the eight priority values (traffic classes
0 – 7) are divided between the two queues in accordance with IEEE
802.1p recommendations — that is, queue 1 (high priority) has classes
4, 5, 6, and 7 and queue 2 (low priority) has classes 0, 1, 2, and 3.
If CoS is disabled (indicated at the top of the display), the display
reflects the most recent configuration even though it is no longer
active.
