Release R.11.17 Enhancements
1.
Identify the TCP or UDP port-number classifier you want to use for assigning a DSCP policy.
2.
Determine the DSCP policy for packets carrying the selected TCP or UDP port number or range
of port numbers.
a.
Determine the DSCP you want to assign to the selected packets. (This codepoint will be used
to overwrite (re-mark) the DSCP carried in packets received from upstream devices.)
b. Determine the 802.1p priority you want to assign to the DSCP.
3.
Configure the DSCP policy by using qos dscp-map to configure the priority to the codepoint you
selected in step
2step
N o t e
A codepoint must have an 802.1p priority assignment (0 - 7) before you can configure a policy for
prioritizing packets by TCP or UDP port numbers or a range of port numbers. If a codepoint you want
to use shows No-override in the Priority column of the DSCP map (show qos dscp-map), then you must
assign a 0 - 7 priority before proceeding.
4.
Configure the switch to assign the DSCP policy to packets with the specified TCP or UDP port
number or range of port numbers.

a.
Syntax: [no] qos <udp-port | tcp-port> <1-65535> [dscp < 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.)
