Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure QoS for Outbound Traffic
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. 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.
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:
No-override
for
most codepoints. See table 6-11 on page 6-59.)
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 >
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 3 on page
6-24.) 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
)
no qos < udp-port | tcp-port > < tcp-udp port number >
Deletes the specified UDP or TCP port number as a QoS
classifier.
