Description
The total number of input datagrams received from interfaces, including those
received in error.
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, and so on.
The number of input datagrams discarded because the IP address in their IP header
destination field was not a valid address to be received at this 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.
The number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
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).
This counter does not include any datagrams discarded while awaiting re-assembly.
The total number of input datagrams successfully delivered to IP user-protocols
(including ICMP).
The total number of IP datagrams that local IP user-protocols (including ICMP)
supplied to IP in requests for transmission.
This counter does not include any datagrams counted in ipForwDatagrams.
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).
This counter would include datagrams counted in ipForwDatagrams if any such
packets met this (discretionary) discard criterion.
The default value inserted into the Time-To-Live (TTL) field of the IP header of
datagrams originated at this switch, whenever a TTL value is not supplied by the
transport layer protocol.
