Command Reference Guide
rtp qos dscp <value>
Use the rtp qos dscp command to configure the maximum Realtime Transport Protocol (RTP) quality of
service (QoS) parameters for differentiated services code point (DSCP).
Syntax Description
<value>
Default Values
By default, no RTP QoS DSCP is configured for this interface.
Command History
Release 9.3
Release 11.1
Functional Notes
By setting the rtp qos dscp value on an individual trunk or user, you will override the global rtp qos dscp
setting for RTP packets. QoS is set using a DSCP value. Valid DSCP values are 10 to 63, and a higher
DSCP value has a higher priority. The default DSCP value for RTP is 46. Remember that if you are using a
public IP connection, such as the Internet, for Voice over Internet Protocol (VoIP), end-to-end QoS may not
be guaranteed. The default DSCP value for Session Initiation Protocol (SIP) is 26. To configure QoS for
the RTP traffic that carries the voice conversation, use the command ip rtp qos dscp followed by the
desired DSCP value.
Usage Examples
By setting the rtp qos dscp value on an individual trunk or user, you will override the global rtp qos dscp
setting for RTP packets. The following example sets the DSCP value for RTP packets that trunk T02
generates to 60.
(config)#voice trunk t02 type isdn
(config-t02)#rtp qos dscp 60
60000CRG0-35E
Configures the RTP QoS parameter for DSCP. Enter a value between 10
and 63.
