The traffic prioritization feature supported by the Switch
is compatible with the relevant sections of the IEEE
802.1D standard (incorporating IEEE 802.1p).
This Switch uses the Weighted Round Robin (WRR)
algorithm to determine the frequency at which it
services each priority queue. The Switch allows you to
choose between using IP Precedence or DSCP
(Differentiated Services Code Point) priority. When either
of these services is enabled, the priorities are mapped to
a Class of Service value by the Switch, and the traffic
then sent to the corresponding output queue.
