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 datagrams, 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 Gate-
ways, this counter will include only those packets, which were Source-Routed
via this entity (the switch), and the Source- Route option processing was success-
ful.

ipInUnknownProtos The number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
ipInDiscards
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 dis-
carded while awaiting re-assembly.
