Figure 23: Filter Policy Components

Filter (mandatory) — This is the value which identifies the filter.
Description (optional) — The description provides a brief overview of the filter's features.
Scope (mandatory) — A filter policy must be defined as having either an exclusive scope
for one-time use, or a template scope which enables its use with multiple SAPs and
interfaces.
Default action (mandatory) — The default action specifies the action to be applied to
packets when no action is specified in the IP or MAC filter entries or when the packets do
not match the specified criteria.
Entry ID (one or more) — Each entry represents a collection of filter match criteria.
Packet matching begins the comparison process with the criteria specified in the lowest
entry ID.
Entries identify attributes which define matching conditions and actions. All criteria in the
entry must match the specified action to be taken. Each entry consists of the following
components:
→ Entry ID (mandatory) — This value determines the order amongst all entry IDs,
within a specific filter ID, in which the matching criteria specified in the collection is
compared. Packets are compared to entry IDs in an ascending order.
→ Description (optional) — The description should provide a brief overview of the entry
ID criteria.
→ Action (mandatory) — An action parameter must be specified for the entry to be
active. Any filter entry without an action parameter specified will be considered
incomplete and be inactive.
→ Packet matching criteria — You can input and select criteria to create a specific
template through which packets are compared and either forwarded or dropped,
depending on the action specified. See
