Enumeration Type Documentation
◆ Icmpv6DestUnreachableCode
◆ Icmpv6ParamProblemCode
◆ Icmpv6TimeExceededCode
◆ Icmpv6Type
| enum Icmpv6Type |
ICMPv6 message type.
The type field indicates the type of the message. Its value determines the format of the remaining data

Enable support for ICMPv6 Echo Request messages.
- Parameters
-
[in] interface Underlying network interface [in] enable This flag specifies whether the host will respond to ICMPv6 Echo Requests. When the flag is set to FALSE, incoming ICMPv6 Echo Request messages will be dropped
- Returns
- Error code
◆ icmpv6EnableMulticastEchoRequests()
| error_t icmpv6EnableMulticastEchoRequests | ( | NetInterface * | interface, |
| bool_t | enable | ||
| ) |
Enable support for multicast ICMPv6 Echo Request messages.
- Parameters
-
[in] interface Underlying network interface [in] enable This flag specifies whether the host will respond to multicast ICMPv6 Echo Requests. When the flag is set to FALSE, incoming ICMPv6 Echo Request messages destined to a multicast address will be dropped
- Returns
- Error code

Variable Documentation
◆ __packed_struct
| typedef __packed_struct |
ICMPv6 header.
ICMPv6 Echo Request and Echo Reply messages.
ICMPv6 Parameter Problem message.
ICMPv6 Time Exceeded message.
ICMPv6 Packet Too Big message.
ICMPv6 Destination Unreachable message.
ICMPv6 Error message.
A Destination Unreachable message is generated in response to a packet that cannot be delivered to its destination address for reasons other than congestion
A Packet Too Big message is sent by a router in response to a packet that it cannot forward because the packet is larger than the MTU of the outgoing link
A Time Exceeded message is sent by a router when it receives a packet with a Hop Limit of zero
A Parameter Problem message is sent by an IPv6 node when it finds a problem with a field in the IPv6 header or extension headers such that it cannot complete processing the packet
Every node must implement an ICMPv6 Echo responder function that receives Echo Requests and sends corresponding Echo Replies
