Creating an IPv4 Filter Policy
Configuring and applying filter policies is optional. Each filter policy must have the
following:
• The filter type specified (IP)
• A filter policy ID
• A default action, either drop or forward
• Filter policy scope specified, either exclusive or template
• At least one filter entry with matching criteria specified
• Optionally, an existing filter policy can have a Filter Name assigned, that can then be
used in CLI to reference that filter policy including assigning it to SAPs and/or
network interfaces.
IPv4 Filter Entry
Within a filter policy, configure filter entries which contain criteria against which ingress,
egress, or network traffic is matched. The action specified in the entry determine how the
packets are handled, such as dropping or forwarding.
• Enter a filter entry ID. The system does not dynamically assign a value.
• Assign an action.
• Specify matching criteria.
The following displays an IPv4 filter entry configuration example.
