STATUS—Supported
• IpInAddrErrors: 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 that are not IP routers and therefore do not forward datagrams, this counter includes
datagrams discarded because the destination address was not a local address.
STATUS—Supported
• IpInNoRoutes: Number of input datagrams discarded because there was a problem with
determination of inbound interface or a problem with determination of a route back to the source of
the datagram [not in the IP Management Information Base (ip-mib)].
STATUS—Supported
• IpInDiscards: The number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but they were discarded (for example, discarded for lack of buffer
space). This counter does not include any datagrams discarded while awaiting reassembly.
STATUS—Not supported
• IpInDelivers: The total number of input datagrams successfully delivered to IP user-protocols
[including Internet Control Message Protocol (ICMP)].
STATUS—Supported
• IpOutRequests: The total number of IP datagrams that local IP user-protocols [including Internet
Control Message Protocol (ICMP)] supplied to IP in requests for transmission. This counter does not
include any datagrams counted in ipForwDatagrams.
STATUS—Supported
• IpOutDiscards: The number of output IP datagrams for which no problem was encountered to prevent
their transmission to their destination, but they were discarded (for example, output IP datagrams
discarded for lack of buffer space). This counter includes datagrams counted in ipForwDatagrams, if
any of the packets met this (discretionary) discard criterion.
STATUS—Supported
• IpOutNoRoutes: The number of IP datagrams discarded because no route could be found to transmit
them to their destination. This counter includes any packets counted in ipForwDatagrams that meet
this `no-route' criterion. This includes any datagrams that a host cannot route because all of its
default routers are down.
STATUS—Supported
• IpReasmTimeout: The maximum number of seconds for which received fragments are held while they
are awaiting reassembly at this entity.
STATUS—Not supported
• IpReasmReqds: The number of IP fragments received that required reassembly at this entity.
STATUS—Not supported
• IpReasmOKs: The number of IP datagrams successfully reassembled.
STATUS—Not supported
• IpReasmFails: The number of failures detected by the IP reassembly algorithm (for example: timed
out, errors, and so forth). This is not necessarily a count of discarded IP fragments because some
algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by
combining them as they are received.
