InReceives |
Indicates the total number of input datagrams received from interfaces, including those received in error. |
InHdrErrors |
Indicates the number of input datagrams discarded due to errors in their IP headers, including bad checksums, version number
mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options.
|
InNoRoutes |
Indicates the number of input IP datagrams discarded because no route is found to transmit them to their destination. |
InAddrErrors |
Indicates the 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. This count includes invalid addresses (for example, 0.0.0.0) and addresses of
unsupported Classes (for example, Class E). For entities which are not IP Gateways and therefore do not forward datagrams,
this counter includes datagrams discarded because the destination address was not a local address.
|
InUnknownProtos |
Indicates the number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported
protocol.
|
InTruncatedPkts |
Indicates the number of input IP datagrams discarded because the datagram frame did not carry enough data. |
InDiscards |
Indicates the number of input IP datagrams for which no problems were encountered to prevent their continued processing, but
which were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded
while awaiting reassembly.
|
InDelivers |
Indicates the total number of input datagrams successfully delivered to IP user-protocols (including ICMP). |
OutForwDatagrams |
Indicates the number of datagrams for which this entity was not their final IP destination and for which it was successful
in finding a path to their final destination. In entities that do not act as IP routers, this counter will include only those
datagrams that were Source-Routed through this entity, and the Source-Route processing was successful.
|
OutRequests |
Indicates the 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.
|
OutDiscards |
Indicates the number of output IP datagrams for which no problem was encountered to prevent their transmission to their destination,
but which were discarded (for example, for lack of buffer space).
Note:
This counter includes datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion.
|
|
OutFragOKs |
Indicates the number of IP datagrams that are successfully fragmented. |
OutFragFails |
Indicates the number of IP datagrams that are discarded because they needed to be fragmented but are not. This includes IPv4
packets that have the DF bit set and IPv6 packets that are being forwarded and exceed the outgoing link MTU.
|
OutFragCreates |
Indicates the number of output datagram fragments that are generated because of IP fragmentation. |
ReasmReqds |
Indicates the number of IP fragments received which needed to be reassembled at this entity. |
ReasmOKs |
Indicates the number of IP datagrams successfully reassembled. |
ReasmFails |
Indicates the number of failures detected by the IP re-assembly algorithm (for whatever reason: timed out, errors). 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.
|
InMcastPkts |
Indicates the number of IP multicast datagrams received. |
OutMcastPkts |
Indicates the number of IP multicast datagrams transmitted. |
