Description

Events generated by the Network - IPv6 Core functions.

The Network IPv6 Core functions generate events that report events in the network core of Internet Protocol version 6 and help in troubleshooting.

Function Documentation

__STATIC_INLINE void EvrNetIP6_DestinationAddressNull ( uint16_t  if_id)

Event on IP6 destination address not provided (Error)

Parameters
if_idnetwork interface identifier

The event DestinationAddressNull is created when the internal send_frame function wants to send the IPv6 frame and finds out, that the destination address is not specified. The IPv6 header can not be created and therefore the frame is not sent.

Value in the Event Recorder shows:

  • netif: network interface identifier.
__STATIC_INLINE void EvrNetIP6_FrameTooShort ( uint16_t  if_id,
uint32_t  length,
uint32_t  min_length 
)

Event on IP6 receive frame too short (Error)

Parameters
if_idnetwork interface identifier
lengthframe length in bytes
min_lengthminimum length of the frame

The event FrameTooShort is created when the network library receives the IPv6 frame that is too short. The frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • len: length of the received frame in bytes.
  • min: minimum valid frame length in bytes.
__STATIC_INLINE void EvrNetIP6_InitCore ( uint16_t  if_id)

Event on IP6 core initialize (Op)

Parameters
if_idnetwork interface identifier

The event InitCore is created when the IPv6 core is initialized, that is, when the function netInitialize is executed. It also informs you of the default network interface assigned to access the Internet.

Value in the Event Recorder shows:

  • default: default network interface for internet access.
__STATIC_INLINE void EvrNetIP6_InterfaceNotSupported ( uint16_t  if_id)

Event on IP6 network interface not supported (Error)

Parameters
if_idnetwork interface identifier

The event InterfaceNotSupported is created when the network library receives an IPv6 frame on the network interface that does not support the IPv6. The IPv6 frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
__STATIC_INLINE void EvrNetIP6_InvalidIpVersion ( uint16_t  if_id,
uint8_t  ip_version 
)

Event on IP6 invalid protocol version (Error)

Parameters
if_idnetwork interface identifier
ip_versionIPv6 protocol version value

The event InvalidIpVersion is created when the network library receives an IPv6 frame that has an unrecognized IP version encoded in the IPv6 header. The IP version should be 6, all other values are invalid. The frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • ver: received IPv6 protocol version.
__STATIC_INLINE void EvrNetIP6_ProtocolUnknown ( uint16_t  if_id,
uint8_t  ip6_protocol 
)

Event on IP6 unknown protocol type in sending frame (Error)

Parameters
if_idnetwork interface identifier
ip6_protocolunknown IPv6 protocol type value

The event ProtocolUnknown is created when the network library wants to send the IPv6 frame, but the provided IPv6 protocol type is not supported. The frame is therefore not sent.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • proto: unknown protocol type.
__STATIC_INLINE void EvrNetIP6_ReceiveFrame ( uint16_t  if_id,
uint32_t  length 
)

Event on IP6 receive frame (Op)

Parameters
if_idnetwork interface identifier
lengthframe length in bytes

The event ReceiveFrame is created when the network library receives the IPv6 frame. The frame can come from any interface.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • len: length of the received IPv6 frame in bytes.
__STATIC_INLINE void EvrNetIP6_SendFrame ( uint16_t  if_id,
uint8_t  ip6_protocol,
uint32_t  length 
)

Event on IP6 send frame (Op)

Parameters
if_idnetwork interface identifier
ip6_protocolIPv6 protocol type
  • 6: TCP
  • 17: UDP
  • 58: ICMP6
lengthframe length

The event SendFrame is created when the internal send_frame function wants to send the IPv6 frame. The IPv6 header is constructed and the frame is sent to the transfer interface.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • proto: IPv6 protocol type (TCP, UDP, ICMPv6).
  • len: length of the IPv6 frame payload.
__STATIC_INLINE void EvrNetIP6_SetDefaultInterface ( uint16_t  if_id)

Event on IP6 set default interface for internet access (Op)

Parameters
if_idnetwork interface identifier

The event SetDefaultInterface is created when the system wants to change the network interface used to access the internet. This usually happens when the netIF_SetDefault function is executed.

Value in the Event Recorder shows:

  • netif: network interface identifier.
__STATIC_INLINE void EvrNetIP6_ShowFrameHeader ( const void *  ip6_header)

Event on IP6 display frame header (Detail)

Parameters
ip6_headerpointer to IPv6 frame header of 40 bytes
  • VerClass (1 byte)
  • ClassFlow (1 byte)
  • Flow (2 bytes)
  • Len (2 bytes)
  • NextHdr (1 byte)
  • HopLim (1 byte)
  • SrcAddr (16 bytes)
  • DstAddr (16 bytes)

The event ShowFrameHeader is created when the network library wants to display detailed information about the IPv6 header.

Value in the Event Recorder shows:

  • dst: destination IPv6 address.
  • src: source IPv6 address.
  • proto: protocol type (TCP, UDP, ICMPv6).
  • hops: hop limit.
  • len: length of the received frame in bytes.
__STATIC_INLINE void EvrNetIP6_SourceAddressNull ( uint16_t  if_id)

Event on IP6 source address not provided (Error)

Parameters
if_idnetwork interface identifier

The event SourceAddressNull is created when the internal send_frame function wants to send the IPv6 frame and finds out, that the local address is not specified. The IPv6 header can not be created and therefore the frame is not sent.

Value in the Event Recorder shows:

  • netif: network interface identifier.
__STATIC_INLINE void EvrNetIP6_UninitCore ( void  )

Event on IP6 core de-initialize (Op)

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

Value in the Event Recorder shows:

  • ip6
__STATIC_INLINE void EvrNetIP6_WrongDestinationAddress ( uint16_t  if_id,
const uint8_t *  ip6_addr 
)

Event on IP6 wrong destination address (Op)

Parameters
if_idnetwork interface identifier
ip6_addrpointer to IPv6 destination address

The event WrongDestinationAddress is created when the network library receives an IPv6 frame that has an invalid destination address. The IPv6 frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • ip: received destination IPv6 address.
__STATIC_INLINE void EvrNetIP6_WrongMulticastProtocol ( uint16_t  if_id,
uint8_t  ip6_protocol 
)

Event on IP6 wrong multicast protocol type (Error)

Parameters
if_idnetwork interface identifier
ip6_protocolreceived protocol type
Remarks
Only UDP multicast frames are allowed.

The event WrongMulticastProtocol is created when the network library receives an IPv6 multicast frame that has an invalid protocol type. The IPv6 frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • proto: received protocol type (TCP, ICMPv6).
