Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic

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 policy 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. For
IPv4 packets, the DSCP will be replaced by the codepoint
specified in this command. (Default:
most codepoints. See table 8-14 on page 8-63.)
Syntax: qos < udp-port | tcp-port > < tcp or udp port number > dscp < codepoint >
Assigns a DSCP policy to outbound packets having the
specified TCP or UDP application port number and
overwrites the DSCP in these packets with the assigned
<codepoint >
ority and determines the packet's queue in the out-
bound port to which it is sent. (The
configured with an 802.1p setting. See step 3 on page
8-27.) If the packet leaves the switch on a tagged port,
it carries the 802.1p priority with it to the next down-
stream device. (Default:
no qos < udp-port | tcp-port > < tcp-udp port number >
Deletes the specified UDP or TCP port number as a QoS
