What to Do Next
If you configure or remove the default MQoS while the CMTS is sending multicast traffic, duplicate traffic
is generated for approximately 3 minutes (or 3 times the query interval).
Note
Configuring Global Tunnel Group Settings for Advanced-Mode DSG 1.2
This procedure configures global and interface-level commands on the Cisco CMTS router to enable DSG
tunnel groups. A DSG tunnel group is used to bundle some DSG channels together and associate them to a
MAC domain interface.
Global A-DSG 1.2 Tunnel Settings
This procedure sets and enables global configurations to support both A-DSG 1.2 clients and agents. Additional
procedures provide additional settings for these clients and agents.
Before You Begin
When DOCSIS Set-top Gateway (DSG) is configured to have quality of service (QoS) for tunnel, ensure that
the default multicast QoS (MQoS) is also configured. For more information, see
Multicast Quality of Service, on page 14
.
The DSG tunnel service class configuration is rejected, if default MQoS is not configured.
