◆ EvrNetICMP6_ChecksumFailed()

__STATIC_INLINE void EvrNetICMP6_ChecksumFailed ( uint16_t  if_id,
uint32_t  length 
)

Event on ICMP6 frame checksum check failed (Error)

Parameters
if_idnetwork interface identifier
lengthframe length in bytes

The event ChecksumFailed is created when the network library has checked the checksum on the received ICMPv6 frame and the verification failed. The ICMPv6 frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • len: length of the ICMPv6 frame in bytes.

__STATIC_INLINE void EvrNetICMP6_EchoReplyDisabled ( uint16_t  if_id)

Event on ICMP6 sending echo reply disabled (Op)

Parameters
if_idnetwork interface identifier

The event EchoReplyDisabled is created when the network library receives an ECHO request, but the ECHO response is disabled in the interface configuration for IPv6. This configuration option is rarely enabled, usually for security reasons only.

Value in the Event Recorder shows:

  • netif: network interface identifier.

Parameters
if_idnetwork interface identifier
codereceived ICMPv6 code
code_validvalid ICMPv6 code

The event EchoReplyWrongCode is created when the network library receives the ICMPv6 echo reply, but the code byte is invalid. The ICMPv6 frame is therefore discarded.

Value in the Event Recorder shows:

Parameters
if_idnetwork interface identifier
eidreceived echo identifier
eid_validvalid echo identifier

The event EchoReplyWrongId is created when the network library receives the ICMPv6 echo reply, but the echo identifier is not identical to the identifier that was sent in echo request. The ICMPv6 frame is therefore discarded.
