The event RefreshEntry is created when the network library wants to refresh the required ARP entry in the cache. This happens when the ARP entry expires, and the type of entry is Fixed-IP or Inuse-IP.

Value in the Event Recorder shows:

netif: network interface identifier.
entry: identifier of the host cache entry.

◆ EvrNetARP_ResolveEntry()

__STATIC_INLINE void EvrNetARP_ResolveEntry	(	uint16_t	if_id,
		uint32_t	entry
	)

Event on resolve ARP cache entry (Op)

Parameters

if_id	network interface identifier
entry	cache entry number

The event ResolveEntry is created when the network library wants to resolve the required ARP entry in the cache. This usually happens when the ARP entry is created, but it is not yet resolved or has expired.

Value in the Event Recorder shows:

netif: network interface identifier.
entry: identifier of the host cache entry.

The event SenderAddressInvalid is created when the network library receives the ARP frame, checks the protocol and hardware address of the sender and finds that they are invalid. The frame is therefore discarded. This usually happens in network attacks.

Value in the Event Recorder shows:

netif: network interface identifier.

Parameters

if_id	network interface identifier
opcode	operation code of sending message 0x0001: ARP Request 0x0008: Inverse ARP Request

The event SendRequest is created when the network library wants to send an ARP request message.

opcode: operation code (ARP_REQUEST, InARP_REQUEST).

◆ EvrNetARP_ShowFrameHeader()

__STATIC_INLINE void EvrNetARP_ShowFrameHeader ( const void * arp_header )

Event on ARP display send/receive frame header (Detail)

Parameters

arp_header

pointer to ARP frame header of 28 bytes

ProtLen (1 byte)
OpCode (2 bytes)
SendHwAddr (6 bytes)
SendIpAddr (4 bytes)
TargHwAddr (6 bytes)
TargIpAddr (4 bytes)

The event ShowFrameHeader is created when the network library wants to display detailed information about the ARP header.

Value in the Event Recorder shows:

op: operation code (ARP_REQUEST, ARP_REPLY, RARP_REQUEST, RARP_REPLY, InARP_REQUEST, InARP_RESPONSE).
spa: sender protocol IP address.
tpa: target protocol IP address.
sha: sender hardware MAC address.
tha: target hardware MAC address.

◆ EvrNetARP_UninitCache()

__STATIC_INLINE void EvrNetARP_UninitCache ( uint16_t if_id )

Event on ARP cache de-initialize (Op)

Parameters

if_id network interface identifier

The event UninitCache is created when the function netUninitialize is executed.

Value in the Event Recorder shows:

netif: network interface identifier.

◆ EvrNetARP_UnresolvedIpAddress()

__STATIC_INLINE void EvrNetARP_UnresolvedIpAddress	(	uint16_t	if_id,
		const uint8_t *	mac_addr
	)

Event on ARP unresolved IP address in cache (Op)

Parameters

if_id	network interface identifier
mac_addr	pointer to MAC cache address

The event UnresolvedIpAddress is created when the network library wants to find the host in the ARP cache table to resolve its IP address, but the host is in the process of resolving. IP address is not yet valid.

Value in the Event Recorder shows:

netif: network interface identifier.
mac: MAC address of the host being searched in the cache.

◆ EvrNetARP_UnresolvedMacAddress()

__STATIC_INLINE void EvrNetARP_UnresolvedMacAddress	(	uint16_t	if_id,
		const uint8_t *	ip4_addr
	)

Event on ARP unresolved MAC address in cache (Error)

Parameters

if_id	network interface identifier
ip4_addr	pointer to requested IP address

The event UnresolvedMacAddress is created when the network library wants to find the host in the ARP cache table to resolve its MAC address, but the host is in the process of resolving. MAC address is not yet valid.

Value in the Event Recorder shows:

netif: network interface identifier.
ip: IP address of the host being searched in the cache.

◆ EvrNetARP_UsingGateway()

__STATIC_INLINE void EvrNetARP_UsingGateway	(	uint16_t	if_id,
		const uint8_t *	ip4_addr
	)

Event on ARP use gateway to access external address (Op)

Parameters

if_id	network interface identifier
ip4_addr	pointer to IP address of a gateway

The event UsingGateway is created when the network library wants to find the non-local host in the ARP cache table. The network library uses the gateway to access the host.

Value in the Event Recorder shows:

netif: network interface identifier.
gw: IP address of the default gateway.

◆ EvrNetARP_WrongIpAddress()

__STATIC_INLINE void EvrNetARP_WrongIpAddress	(	uint16_t	if_id,
		const uint8_t *	ip4_addr
	)

Event on ARP wrong destination IP address received (Op)

Parameters

if_id	network interface identifier
ip4_addr	pointer to IP address

The event WrongIpAddress is created when the network library receives the ARP frame, but the target IP address is not the same as our local IP address. The frame is therefore discarded.

Value in the Event Recorder shows:

netif: network interface identifier.
ip: received target IP address.

◆ EvrNetARP_WrongMacAddress()

__STATIC_INLINE void EvrNetARP_WrongMacAddress	(	uint16_t	if_id,
		const uint8_t *	mac_addr
	)

Event on ARP wrong destination MAC address received (Op)

Parameters

if_id	network interface identifier
mac_addr	pointer to MAC address

The event WrongMacAddress is created when the network library receives Inverse ARP frame, but the target MAC address is not the same as our local MAC address. The frame is therefore discarded.

Value in the Event Recorder shows:

netif: network interface identifier.
mac: received target MAC address.

◆ EvrNetARP_WrongResponse()

__STATIC_INLINE void EvrNetARP_WrongResponse ( uint16_t if_id )

Event on ARP wrong response received (Error)

Parameters

if_id network interface identifier

The event WrongResponse is created when the network library receives a valid ARP response, but the ARP service waits for none. The received ARP frame is therefore discarded. This usually happens in network attacks.

Value in the Event Recorder shows:

netif: network interface identifier.
