Configure Filter
Filters restrict select types of user data on a particular interface. There are three
steps to implementing a filter in the BitStorm 4800:
„
Define filter rules (see
Configure Filter-Rule
on page A-10)
„
Define a named filter comprising one or more rules (see Table A-7, Configure
Filter Command )
„
Bind the filter to an interface (see Configure Filter-Binding on page A-9)
The configure filter command creates and deletes filters.
Table A-7. Configure Filter Command

The configure filter create command creates a filter based on existing filter rules.
