scenario in a converged services environment is that voice traffic will be given highest priority, best effort data (HSD) will
be given lowest priority, and DSG data will be given a priority somewhere in between. When determining the priority to be
applied to DSG data, priority for HSD data, voice signaling data, and voice data itself should be taken into account.
DSG Classifier
The DSG Classifier parameters are:
Classifier ID (mandatory)
DSG Tunnel ID (mandatory)
Classifier Priority (defaults to zero, which is the lowest priority)
DSG Tunnel Destination IP Address (mandatory)
DSG Tunnel Source IP Address (optional)
Mask (optional)
Destination Port Range (optional)
These parameters make up the DSG Classifier in the DCD. Note that the classifier ID must be unique per CMTS. For all
parameters that are not mandatory or do not have a default value are not included in the DCD when they are not explicitly
configured.
The command to configure a DSG classifier is:
configure cable dsg tunnel <dsgTunnelId> classifier <dsgClassId> [priority <classPri>] dest-ip
<destIP> [source-network <sourceIp>[/<maskLen>]] [dest-port-range <portStart>-<portend>]
[include-in-dcd]
By default, the DSG Classifier is not included in the DCD, unless the keyword
include-in-dcd
is specified on the
command line. The following command includes the classifier in the DCD:
configure cable dsg tunnel <dsgTunnelId> classifier <dsgClassId> include-in-dcd
Note: A classifier must be configured to route packets to a tunnel, even if that classifier is not included in the DCD.
To remove the classifier from the DCD, use the
NO
version of the command. The classifier ID will be suppressed from the
DSG rule in the DCD if the classifier is not configured to be included in the DCD.
