Configuring IP RTP Classification

The IP Real-time Transport Protocol (RTP) is a transport protocol for real-time applications that transmit data
such as audio or video and is defined by RFC 3550. Although RTP does not use a common TCP or UDP port,
you typically configure RTP to use ports 16384 to 32767. UDP communications uses an even-numbered port
and the next higher odd-numbered port is used for RTP Control Protocol (RTCP) communications.
You can configure classification based on UDP port ranges, which are likely to target applications using RTP.

Configuring IP RTP Classification
Purpose
hyphen, or underscore characters, is case
sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets
based on list of CoS values. Values can range
from 0 to 7.
Use the not keyword to match on values that
do not match the specified range.
Exits global class-map queuing mode, and
enters configuration mode.
Saves this configuration change.
Purpose
Enters global configuration mode.
Creates or accesses the class map named
class-map-name and enters class-map mode.
The class map name can contain alphabetic,
hyphen, or underscore characters, is case
sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets
based on a range of lower and upper UDP port
numbers, which is likely to target applications
using RTP. Values can range from 2000 to
65535.
