Ip layer counters.

Fields

deliver_unicast: C

Count of incoming IP unicast packets delivered.

deliver_multicast: C

Count of incoming IP multicast packets delivered.

dispatch_receive_ip_packet: C

Count of incoming IP packets that are dispatched to the appropriate protocol.

dispatch_receive_ip_packet_other_host: C

Count of incoming IP packets destined to another host.

receive_ip_packet: C

Count of incoming IP packets received by the stack.

send_ip_packet: C

Count of sent outgoing IP packets.

forwarding_disabled: C

Count of packets to be forwarded which are instead dropped because forwarding is disabled.

forward: C

Count of incoming packets forwarded to another host.

no_route_to_host: C

Count of incoming packets which cannot be forwarded because there is no route to the destination host.

mtu_exceeded: C

Count of incoming packets which cannot be forwarded because the MTU has been exceeded.

ttl_expired: C

Count of incoming packets which cannot be forwarded because the TTL has expired.

receive_icmp_error: C

Count of ICMP error messages received.

fragment_reassembly_error: C

Count of IP fragment reassembly errors.

need_more_fragments: C

Count of IP fragments that could not be reassembled because more fragments were needed.

invalid_fragment: C

Count of IP fragments that could not be reassembled because the fragment was invalid.

fragment_cache_full: C

Count of IP fragments that could not be reassembled because the stack’s per-IP-protocol fragment cache was full.

parameter_problem: C

Count of incoming IP packets not delivered because of a parameter problem.

unspecified_destination: C

Count of incoming IP packets with an unspecified destination address.

unspecified_source: C

Count of incoming IP packets with an unspecified source address.

invalid_source: C

Count of incoming IP packets with an invalid source address. See the definitions of net_types::ip::Ipv4SourceAddr and net_types::ip::Ipv6SourceAddr for the exact requirements.

dropped: C

Count of incoming IP packets dropped.

tx_illegal_loopback_address: C

Number of frames rejected because they’d cause illegal loopback addresses on the wire.

version_rx: I::RxCounters<C>

Version specific rx counters.

multicast_no_interest: C

Count of incoming IP multicast packets that were dropped because The stack doesn’t have any sockets that belong to the multicast group, and the stack isn’t configured to forward the multicast packet.

invalid_cached_conntrack_entry: C

Count of looped-back packets that held a cached conntrack entry that could not be downcasted to the expected type. This would happen if, for example, a packet was modified to a different IP version between EGRESS and INGRESS.

fragmentation: FragmentationCounters<C>

IP fragmentation counters.

socket_egress_filter_dropped: C

Number of packets filtered out by the socket egress filter.
