Verifying the DOCSIS 1.1 Configuration
To display the DOCSIS 1.1 QoS statistics, including the type of service flow and packet classifiers being
used for each queue, use the show controllers cable-modem qos command:
Router# show controllers cable-modem 0 qos
Queue SID SID SFID TX TX RX RX Capabilities

Step 10
ip qos dscp class-selector media
Example:
Router(config-dial-peer)# ip qos dscp cs5 media
Router(config-dial-peer)#
(Optional) Specifies that the packet’s IP precedence level is
specified in the Differentiated Services Code Point (DSCP)
field in the IP packet. The class-selector specifies the
precedence level:
• cs1—codepoint 1 (precedence 1)
• cs2—codepoint 2 (precedence 2)
• cs3—codepoint 3 (precedence 3)
• cs4—codepoint 4 (precedence 4)
• cs5—codepoint 5 (precedence 5)
• cs5—codepoint 6 (precedence 6)
• cs7—codepoint 7 (precedence 7)
Typically, the ip qos dscp command should be used instead of the ip precedence command.
Step 11
exit
Example:
Router(config-dial-peer)# exit
Router(config)#
Exits dial-peer configuration mode.
Step 12

Example:
Router(config)# gateway
Router(config)#
Enables the VoIP gateway on the router.
Step 13
