◆ GvcpForceIpRequestLayer() [1/2]

pcpp::GvcpForceIpRequestLayer::GvcpForceIpRequestLayer	(	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

◆ GvcpForceIpRequestLayer() [2/2]

pcpp::GvcpForceIpRequestLayer::GvcpForceIpRequestLayer	(	const MacAddress &	macAddress,
		const IPv4Address &	ipAddress,
		const IPv4Address &	subnetMask,
		const IPv4Address &	gatewayIpAddress,
		GvcpFlag	flag = `0`,
		uint16_t	requestId = `1`
	)

A constructor that creates a new GVCP force IP command

Parameters

[in]	macAddress	The MAC address of the device to configure
[in]	ipAddress	The IP address to force on the device
[in]	subnetMask	The subnet mask to force on the device
[in]	gatewayIpAddress	The default gateway to force on the device
[in]	flag	The flag, optional
[in]	requestId	The request ID, optional. The spec requires a non-zero value

Member Function Documentation

◆ getGatewayIpAddress()

IPv4Address pcpp::GvcpForceIpRequestLayer::getGatewayIpAddress ( ) const

Returns: The default gateway IP address to force on the device

◆ getHeaderLen()

size_t pcpp::GvcpForceIpRequestLayer::getHeaderLen ( ) const

inlineoverridevirtual

Returns: The size of the GVCP header and the force IP command body

Reimplemented from pcpp::GvcpRequestLayer.

◆ getIpAddress()

IPv4Address pcpp::GvcpForceIpRequestLayer::getIpAddress ( ) const

Returns: The IP address to force on the device

◆ getMacAddress()

MacAddress pcpp::GvcpForceIpRequestLayer::getMacAddress ( ) const

Returns: The MAC address of the device to configure

◆ getSubnetMask()

IPv4Address pcpp::GvcpForceIpRequestLayer::getSubnetMask ( ) const

Returns: The subnet mask to force on the device

◆ isDataValid()

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

static

A static method that checks whether the data is a valid GVCP request which is large enough to hold a GVCP force IP command

Parameters

[in]	data	A pointer to the raw data
[in]	dataLen	Size of the data in bytes

Returns: True if the data can be parsed as a GVCP force IP command, false otherwise

◆ serializeLayer()

void pcpp::GvcpForceIpRequestLayer::serializeLayer ( ObjectScope & serializer ) const

overrideprotectedvirtual

Serializes the layer's data into a provided serializer object. This is used for generating serialized representations (like JSON) of the packet layers. This method should be overridden by derived layers to provide specific serialization logic.

Parameters

[in] serializer The object scope serializer to which the layer details should be written.

Reimplemented from pcpp::GvcpRequestLayer.

◆ setGatewayIpAddress()

void pcpp::GvcpForceIpRequestLayer::setGatewayIpAddress ( const IPv4Address & gatewayIpAddress )

Set the default gateway IP address to force on the device

Parameters

[in] gatewayIpAddress The default gateway IP address to set

◆ setIpAddress()

void pcpp::GvcpForceIpRequestLayer::setIpAddress ( const IPv4Address & ipAddress )

Set the IP address to force on the device

Parameters

[in] ipAddress The IP address to set

◆ setMacAddress()

void pcpp::GvcpForceIpRequestLayer::setMacAddress ( const MacAddress & macAddress )

Set the MAC address of the device to configure

Parameters

[in] macAddress The MAC address to set

◆ setSubnetMask()

void pcpp::GvcpForceIpRequestLayer::setSubnetMask ( const IPv4Address & subnetMask )

Set the subnet mask to force on the device

Parameters

[in] subnetMask The subnet mask to set
