Filter Policies
7210 SAS D, E OS Router Configuration Guide Page 71
Configuration Notes
The following information describes filter implementation caveats:
• Creating a filter policy is optional.
• Associating a service with a filter policy is optional.
• When a filter policy is configured, it should be defined as having either an exclusive scope
for one-time use, or a template scope meaning that the filter can be applied to multiple
SAPs.
• A specific filter must be explicitly associated with a specific service in order for packets to
be matched.
• A filter policy can consist of zero or more filter entry. Each entry represents a collection of
filter match criteria. When packets enter the ingress or egress ports, packets are compared
to the criteria specified within the entry or entries.
• When a large (complex) filter is configured, it may take a few seconds to load the filter
policy configuration and be instantiated.
• IP filters applied on an IES SAP cannot match against IP packets containing IP options.
• The action keyword must be entered for the entry to be active. Any filter entry without the
action keyword will be considered incomplete and be inactive.
