Detailed Description

Represents Rapid Spanning Tree Protocol (RSTP)

Constructor & Destructor Documentation

◆ RapidStpLayer()

pcpp::RapidStpLayer::RapidStpLayer	(	uint8_t *	data,
		size_t	dataLen,
		Layer *	prevLayer,
		Packet *	packet
	)

inline

A constructor that creates the layer from an existing packet raw data

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes
[in]	prevLayer	A pointer to the previous layer
[in]	packet	A pointer to the Packet instance where layer will be stored in

Member Function Documentation

◆ getRstpConfHeader()

rstp_conf_bpdu* pcpp::RapidStpLayer::getRstpConfHeader ( ) const

inline

Get a pointer to Rapid STP header

Returns: A pointer to Rapid STP header

◆ getVersion1Len()

uint8_t pcpp::RapidStpLayer::getVersion1Len ( ) const

inline

Returns the length of version1 field. Fixed at 0x0 for Rapid STP

Returns: Length of the version1 field

◆ isDataValid()

static bool pcpp::RapidStpLayer::isDataValid	(	const uint8_t *	data,
		size_t	dataLen
	)

inlinestatic

A static method that validates the input data

Parameters

[in]	data	The pointer to the beginning of a byte stream of an Rapid STP packet
[in]	dataLen	The length of the byte stream

Returns: True if the data is valid and can represent an Spanning Tree packet

◆ toString()

std::string pcpp::RapidStpLayer::toString ( ) const

inlinevirtual

Returns: Returns the protocol info as readable string

Reimplemented from pcpp::StpConfigurationBPDULayer.

Reimplemented in pcpp::MultipleStpLayer.
