Table 5-15 IP Statistics (stats/l3/ip)
Statistics Description
ipInReceives The total number of input datagrams received from interfaces, including
those received in error.
ipInHdrErrors The number of input datagrams discarded due to errors in their IP head-
ers, including bad checksums, version number mismatch, other format
errors, time-to-live exceeded, errors discovered in processing their IP
options, and so forth.
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 (the switch). 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 data-
grams, this counter includes datagrams discarded because the destination
address was not a local address.
ipForwDatagrams The number of input datagrams for which this entity (the switch) 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. In entities which do not
act as IP Gateways, this counter will include only those packets, which
were Source-Routed via this entity (the switch), and the Source- Route
option processing was successful.
ipInUnknownProtos The number of locally addressed datagrams received successfully but dis-
carded because of an unknown or unsupported protocol.
ipInDiscards The number of input IP datagrams for which no problems were encoun-
tered 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 re-assembly.
