DSG Tunnel Groups
DSG tunnels are associated with a DS cable interface via DSG tunnel Groups. The command to associate a group with an
interface and to configure the tunnel group’s parameters is:
configure interface cable-downstream <slot>/<port> cable dsg tunnel-group <tunnelGrpId> [index
<value>] [priority <priority>] [vsp-list <vendorSetId>]
The command to display the DSG tunnel groups assigned to a DS cable interface is:
show interface cable-downstream <slot>/<port> cable dsg tunnel-group
DSG Tunnel Group Parameters
The assignment of the DSG tunnels to DSG tunnel groups was covered in the DSG tunnel Group section above. The DSG
tunnel Group parameters that are part of the DSG rule is:
Rule Priority (defaults to 0, which is the lowest priority in this case)
Vendor-specific Parameters (optional)
The rule priority is mandatory for the DSG rule so if it is not specified when configuring the DSG tunnel Group, the rule
priority takes on a value of zero. If the VSP list is not specified with the command, it is omitted from the DSG rule in the
DCD. Note that this logic applies for all parameters with defaults and those that are optional.
The command to configure the DSG tunnel Group parameters is:
configure interface cable-downstream <slot>/<port> cable dsg tunnel-group <tunnelGrpId> [priority
<priority>] [vsp-list <vendorSetId>]
The commands to display the DSG tunnel group parameters are:
show cable dsg tunnel-group
show interface cable-downstream [<word>] cable dsg tunnel-group
DSG Tunnel Parameters
The DSG tunnel parameters are:
DSG Tunnel Group (mandatory)
Client ID List (mandatory)
DSG Tunnel’s Destination MAC Address (mandatory)
Service Class Name (SCN) (optional; not included in DCD)
