given a QoS priority based on the upper 6 bits of the IP ToS field from the packets as they enter
the switch. The assignment of Diffserv Codepoints to 802.1p priorities is done via the qos
dscp-map command. Any Diffserv Codepoint in an inbound IPv4 packet can be re-mapped to
a different codepoint (and its associated 802.1p priority) on outbound. This is done by using
the syntax: qos type-of-service diff-services <af11..ef|0-63|000000...111111> dscp
<af11..ef|0-63|000000...111111>

to assign priority for IPv4 packets if a QoS classifier uses
this DSCP policy as the method of traffic prioritization.
The mapping also provides the profile for inbound classification
