Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name	Type	Description
PacketFilterBase	simple module	This is a base module for various packet filter modules. Derived modules must implement a single packet matcher function which determines if a packet is to be passed through or filtered out.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"dropped %d/%p pk (%k/%l)"	determines the text that is written on top of the submodule
backpressure	bool	false
popFcs	bool	true

Properties

Name	Value	Description
display	i=block/checker
class	EthernetFcsChecker

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit
packetPushedIn	inet::Packet
packetPulledIn	inet::Packet
packetDropped	inet::Packet
packetPushedOut	inet::Packet
packetPulledOut	inet::Packet
