Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure QoS for Outbound Traffic
Options for Assigning Priority. Priority control options for TCP or UDP
packets carrying a specified TCP or UDP port number include:
■ 802.1p priority
■ DSCP policy (Assigning a new DSCP and an associated 802.1p priority;
inbound packets must be IPv4.)
For a given TCP or UDP port number, you can use only one of the above
options at a time. However, for different port numbers, you can use different
options.
TCP/UDP Port Number Ranges. There are three ranges:
■ Well-Known Ports: 0 - 1023
■ Registered Ports: 1024 - 49151
■ Dynamic and/or Private Ports: 49152 - 65535
For more information, including a listing of UDP/TCP port numbers, go to the
Internet Assigned Numbers Authority
(IANA) website at:

Port Numbers
Assigning 802.1p Priority Based on TCP or UDP Port Number
This option assigns an 802.1p priority to (IPv4) TCP or UDP packets as
described below.
Syntax: qos < udp-port | tcp-port > < tcp or udp port number > priority < 0 - 7 >
Configures an 802.1p priority for outbound packets
having the specified TCP or UDP application port
number. This 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.
