Using Filter Templates
When you create traffic filters, it is important to understand the difference between
a traffic filter template and an actual traffic filter.
A traffic filter template is a reusable, predefined specification for a traffic filter.
Each template contains a complete filter specification (criterion, range, and
action) for one protocol, but is not associated with a specific interface or circuit.
You create an actual traffic filter when you use the Configuration Manager to
apply (save) a traffic filter template to a configured router interface. You can apply
a single template to as many interfaces as you want, thus creating multiple filters
for that protocol.
When you want to add a filter to an interface, you have several options:
• If there is a template that contains the exact filtering instructions you want for
this interface, apply that template to the interface.
• If there is a template that contains filtering instructions similar to what you
want, copy, rename, and edit the template. Then, apply the new template to
the appropriate interface.
• If there is no template containing filtering instructions similar to what you
want for this interface, you must create a template from scratch. Then, apply
the new template to the appropriate interface.
• If there is an existing filter on the interface that contains instructions similar to
what you want, edit the existing filter and save it.
