}Expand description
This struct holds the data needed for the IP, ICMP, TCP, and UDP management information bases for an SNMP agent.
For more details, see RFC1213 and SNMP counter
Fields§
§ip_forwarding: IpForwarding§ip_default_ttl: u32The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this entity, whenever a TTL value is not supplied by the transport layer protocol.
ip_in_receives: u64The total number of input datagrams received from interfaces, including those received in error.
ip_in_hdr_errors: u64The number of input datagrams discarded due to errors in their IP headers.
ip_in_addr_errors: u64The number of input datagrams discarded because the IP address in their IP header’s destination field was not a valid address to be received at this entity.
ip_forw_datagrams: u64The number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination.
ip_in_unknown_protos: u64The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
ip_in_discards: u64The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (e.g., for lack of buffer space).
ip_in_delivers: u64The total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
Note that this counter does not include any datagrams discarded while awaiting re-assembly.
ip_out_requests: u64The total number of IP datagrams which local IP user-protocols (including ICMP) supplied to IP in requests for transmission.
Note that this counter does not include any datagrams counted in ipForwDatagrams.
ip_out_discards: u64The number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (e.g., for lack of buffer space).
Note that this counter would include datagrams counted in
IpForwDatagrams if any such packets met this (discretionary) discard
criterion.
ip_out_no_routes: u64The number of IP datagrams discarded because no route could be found to transmit them to their destination.
Note that this counter includes any packets counted in IpForwDatagrams
which meet this `no-route’ criterion.
Note that this includes any datagarms which a host cannot route because all of its default gateways are down.
ip_reasm_timeout: u64The maximum number of seconds which received fragments are held while they are awaiting reassembly at this entity.
ip_reasm_reqds: u64The number of IP fragments received which needed to be reassembled at this entity.
ip_reasm_oks: u64The number of IP datagrams successfully re-assembled.
ip_reasm_fails: u64The number of failures detected by the IP re-assembly algorithm (for whatever reason: timed out, errors, etc).
Note that this is not necessarily a count of discarded IP fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
ip_frag_oks: u64The number of IP datagrams that have been successfully fragmented at this entity.
ip_frag_fails: u64The number of IP datagrams that have been discarded because they needed
to be fragmented at this entity but could not be, e.g., because their
Don't Fragment flag was set.
ip_frag_creates: u64The number of IP datagram fragments that have been generated as a result of fragmentation at this entity.
icmp_in_msgs: u64The total number of ICMP messages which the entity received.
Note that this counter includes all those counted by icmp_in_errors.
icmp_in_errors: u64The number of ICMP messages which the entity received but determined as having ICMP-specific errors (bad ICMP checksums, bad length, etc.
icmp_in_csum_errors: u64This counter indicates the checksum of the ICMP packet is wrong.
Non RFC1213 field
icmp_in_dest_unreachs: u64The number of ICMP Destination Unreachable messages received.
icmp_in_time_excds: u64The number of ICMP Time Exceeded messages received.
icmp_in_parm_probs: u64The number of ICMP Parameter Problem messages received.
icmp_in_src_quenchs: u64The number of ICMP Source Quench messages received.
icmp_in_redirects: u64The number of ICMP Redirect messages received.
icmp_in_echos: u64The number of ICMP Echo (request) messages received.
icmp_in_echo_reps: u64The number of ICMP Echo Reply messages received.
icmp_in_timestamps: u64The number of ICMP Timestamp (request) messages received.
icmp_in_timestamp_reps: u64The number of ICMP Timestamp Reply messages received.
icmp_in_addr_masks: u64The number of ICMP Address Mask Request messages received.
icmp_in_addr_mask_reps: u64The number of ICMP Address Mask Reply messages received.
icmp_out_msgs: u64The total number of ICMP messages which this entity attempted to send.
Note that this counter includes all those counted by icmp_out_errors.
icmp_out_errors: u64The number of ICMP messages which this entity did not send due to problems discovered within ICMP such as a lack of buffers. This value should not include errors discovered outside the ICMP layer such as the inability of IP to route the resultant datagram. In some implementations there may be no types of error which contribute to this counter’s value.
icmp_out_dest_unreachs: u64The number of ICMP Destination Unreachable messages sent.
icmp_out_time_excds: u64The number of ICMP Time Exceeded messages sent.
icmp_out_parm_probs: u64The number of ICMP Parameter Problem messages sent.
icmp_out_src_quenchs: u64The number of ICMP Source Quench messages sent.
icmp_out_redirects: u64The number of ICMP Redirect messages sent. For a host, this object will always be zero, since hosts do not send redirects.
icmp_out_echos: u64The number of ICMP Echo (request) messages sent.
icmp_out_echo_reps: u64The number of ICMP Echo Reply messages sent.
icmp_out_timestamps: u64The number of ICMP Timestamp (request) messages sent.
icmp_out_timestamp_reps: u64The number of ICMP Timestamp Reply messages sent.
icmp_out_addr_masks: u64The number of ICMP Address Mask Request messages sent.
icmp_out_addr_mask_reps: u64The number of ICMP Address Mask Reply messages sent.
tcp_rto_algorithm: TcpRtoAlgorithm§tcp_rto_min: u64The minimum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds. More refined semantics for objects of this type depend upon the algorithm used to determine the retransmission timeout. In particular, when the timeout algorithm is rsre(3), an object of this type has the semantics of the LBOUND quantity described in RFC 793.
tcp_rto_max: u64The maximum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds. More refined semantics for objects of this type depend upon the algorithm used to determine the retransmission timeout. In particular, when the timeout algorithm is rsre(3), an object of this type has the semantics of the UBOUND quantity described in RFC 793.
tcp_max_conn: i64The limit on the total number of TCP connections the entity can support. In entities where the maximum number of connections is dynamic, this object should contain the value -1.
tcp_active_opens: u64The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
tcp_passive_opens: u64The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
tcp_attempt_fails: u64The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
tcp_estab_resets: u64The number of times TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state.
tcp_curr_estab: u64The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
tcp_in_segs: u64The total number of segments received, including those received in error. This count includes segments received on currently established connections.
tcp_out_segs: u64The total number of segments sent, including those on current connections but excluding those containing only retransmitted octets.
tcp_retrans_segs: u64The total number of segments retransmitted - that is, the number of TCP segments transmitted containing one or more previously transmitted octets.
tcp_in_errs: u64The total number of segments received in error (e.g., bad TCP checksums).
tcp_out_rsts: u64The number of TCP segments sent containing the RST flag.
tcp_in_csum_errors: u64[To be documented.]

udp_in_datagrams: u64The total number of UDP datagrams delivered to UDP users.
udp_no_ports: u64The total number of received UDP datagrams for which there was no application at the destination port.
udp_in_errors: u64The number of received UDP datagrams that could not be delivered for reasons other than the lack of an application at the destination port.
