Syntax: [no] qos < udp-port | tcp-port > <portnum | <range <start > <end>>>
< priority < 0 - 7 > | dscp <codepoint>>
Assigns a DSCP policy to outbound packets having the
specified TCP or UDP application port number or
range of port numbers and overwrites the DSCP in
these packets with the assigned
<codepoint > value. This
policy includes an 802.1p priority and determines the
packet’s queue in the outbound port to which it is sent.
(The
<codepoint > must be configured with an 802.1p
setting. See step step 3.) If the packet leaves the switch
on a tagged port, it carries the 802.1p priority with it
to the next downstream device. (Default:
No-override)
A port range can be from 1 to 65535 (inclusive) ports
or any subset thereof. See “Operating Notes on Using
Port Ranges” on page 43. The minimum port number
must precede the maximum port number in the range.
The no form of the command deletes the specified UDP
or TCP port number or range of port numbers as a QoS
classifier.
Note: If you have specified a range of port numbers,
you must specify the entire range in the no command;
you cannot remove part of a range.
