Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
For example, suppose you wanted to assign these DSCP policies to the packets
identified by the indicated UDP and TDP port applications:
After configuring the DSCP policies for the codepoints you want to use, assign
the DSCP policies to the selected UDP/TCP port applications and display the
result.
• dscp codepoint overwrites the DSCP codepoint in the
IPv4 ToS byte or IPv6 Traffic Class byte of matching
packets with the specified value.
Valid values for the DSCP codepoint are as follows:
- A binary value for the six-bit codepoint from 000000
to 111111.
- A decimal value from 0 (low priority) to 63 (high
priority) that corresponds to a binary DSCP bit set
-An ASCII standard name for a binary DSCP bit set
Type ? to display the list of valid codepoint entries.
no qos < udp-port | tcp-port > < tcp-udp port number | range <start end >>
The no form of the command deletes the specified UDP
or TCP port number or range of port numbers as a QoS
classifier. If you configured a range of port numbers as
the QoS classifier, you must enter the entire range in
the no command; you cannot remove part of a range.
