Modifying Filter Groups Per Cable Modem
The Cuda 12000 allows the network administrator to temporarily modify the
matching criteria of a default filter group on a per cable modem basis.
A default filter group is modified when the network administrator feels it is
necessary to use different matching criteria for a particular cable modem or
CPE device. The modifications are applied as follows:
■The filter group containing the modifications overrides the matching
criteria of the default filter group. These changes do not persist. The next
time the cable modem re-initializes, the changes are wiped out and the
cable modem uses the default filter group.
■The filter group containing the modifications is a temporary assignment
and is not persisted on the Route Server.
■Since a non-default filter group is not persisted, the modifications do not
overwrite the initial source matching criteria of the default filter group.
The following table lists the parameters that you set to modify glob al filter
groups on the Cuda 12000:
