PacketDirectionReverser

simple module

This module is part of the layer 2 architecture. It turns an incoming packet into an outgoing packet simply by removing all attached indication tags and turning some of them into an attached request tag on the packet.

Extends

Name	Type	Description
PacketFlowBase	simple module	This is a base module for various packet flow modules. A packet flow module passes or streams all pushed or pulled packets after processing them from its input to its output.

Parameters

displayStringTextFormat	string	"processed %p pk (%l)"	determines the text that is written on top of the submodule
forwardVlan	bool	true
forwardPcp	bool	true
excludeEncapsulationProtocols	object	[]
