Configuring Ip Rtp Classification - Cisco Nexus 9000 Series Configuration Manual

Configuring Classification
This example shows how to configure the CoS class-map configuration:
switch# conf t
switch(config)# class-map type qos match-all cos6
switch(config-cmap-qos)# match cos 6
switch(config)# class-map type qos match-all cos1
switch(config-cmap-qos)# match cos 1
switch(config)# class-map type qos match-all cos2
switch(config-cmap-qos)# match cos 2
switch(config)# class-map type qos match-all cos3
switch(config-cmap-qos)# match cos 3
switch(config)# class-map type qos match-all cos0
switch(config-cmap-qos)# match cos 0

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.
SUMMARY STEPS
1. configure terminal
2. class-map [type qos] [match-any | match-all] class-name
3. match [not] ip rtp udp-port-value
4. exit
5. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2 class-map [type qos] [match-any | match-all]
class-name
Example:
switch(config)# class-map class_rtp
Purpose
Enters global configuration mode.
Creates or accesses the class map named class-name and then
enters class-map mode. The class-map name can contain
alphabetic, hyphen, or underscore characters, and can be up to 40
characters.
