Detailed Description

Represents network topology change BPDU message of Spanning Tree Protocol

Constructor & Destructor Documentation

pcpp::StpTopologyChangeBPDULayer::StpTopologyChangeBPDULayer	(	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

stp_tcn_bpdu* pcpp::StpTopologyChangeBPDULayer::getStpTcnHeader ( )

inline

Get a pointer to network topology change (TCN) BPDU message

static bool pcpp::StpTopologyChangeBPDULayer::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 Spanning Tree Topology Change BPDU packet
[in]	dataLen	The length of the byte stream

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

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

inlinevirtual

Implements pcpp::Layer.
