EthernetFragmentingMacLayer	compound module	(no description)

Extends¶

Name	Type	Description
ChecksumCheckerBase	simple module	Base module for checksum checkers that verify the integrity of packets. This module filters packets based on their checksum value, dropping packets with invalid checksums. It supports multiple checksum algorithms such as CRC32 and the Internet checksum, and also several checksum modes: disabled, declared correct, declared incorrect, and computed. When in computed mode, it calculates the actual checksum and compares it with the received value.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“dropped {numDroppedPackets}/{numProcessedPackets} pk ({droppedTotalLength}/{processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
backpressure	bool	false
checksumType	string	“ethernet-fcs”
