EthernetFrameClassifier

simple module

Classifier that forwards Ethernet PAUSE frames to the pauseOut gate, and other frames to the defaultOut gate.

This component can be used to build a QoS queue that gives the PAUSE frames the highest priority.

Inheritance diagram

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

Extends

Name	Type	Description
PacketClassifierBase	simple module	This is a base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"classified %p pk (%l)"	determines the text that is written on top of the submodule
reverseOrder	bool	false
