A codepoint must have an 802.1p priority assignment (0 - 7) before you can
configure that codepoint as a criteria for prioritizing packets by source-port.
If a codepoint shows No-override in the Priority column of the DSCP Policy
Table (show qos dscp-map), then you must assign a 0 - 7 priority before
Configure the switch to assign the DSCP policy to packets from the
Syntax: qos dscp-map < codepoint > priority < 0 - 7 >
This command is optional if a priority has already
been assigned to the < codepoint >. The command creates
a DSCP policy by assigning an 802.1p priority to a
specific DSCP. When the switch applies this priority to
a packet, the priority determines the packet's queue in
the outbound port to which it is sent. If the packet leaves
the switch on a tagged port, it carries the 802.1p
priority with it to the next downstream device.
(Default: For most codepoints, No-override. See figure
6-11 on page 6-59 on page 6-59.)
