Assigning Default Filter Groups
Default filter groups are used by cable modems and CPE devices on all cable
interfaces, for upstream and downstream traffic.
You assign four default Subscriber Management filter groups:
■One upstream and one downstream default filter group for ca ble
modems.
■One upstream and one downstream default filter group for C PE devices.
The following applies to default filter groups:
■To assign the default filter group, specify the group ID of a filter group
that you create with the cm-filter command. This filter group contains
the matching criteria to be used as the default filter group.
■Default filter groups are persisted on the Router Server.
■You can use the same default filter group for cable modems and CPE
devices.
■You can use the same default filter group for upstream and downstream
traffic.
The following table lists the parameters that you set to assign default
Subscriber Management filter groups on the Cuda 12000:
