Default TTL Displays the Default ’Time-to-Live’ (TTL) value that the device will
insert into the IP header of a datagram originated at this entity. The
unit will only do so when this value has not been supplied by the
transport layer protocol.
In Datagrams
Received Displays the number of input datagrams that were received
successfully.
In IP Header Error Displays the number of input datagrams discarded as result of
errors in the IP header of the datagrams. Other reasons for
discarding the datagram could be: bad checksum, version number
mismatch, a ’Time-to-Live’ value that had expired, or other format
errors, or errors in processing the IP options.
Invalid Destinations Identifies the number of input datagrams that was discarded as
result of an invalid IP Address value to be received at this entity.
This count includes invalid addresses such as ’0.0.0.0’ and
addresses of unsupported classes (e.g. Class E). If the unit
functions as an IP Gateway, it will not forward datagrams. For such
devices, this counter will also include datagrams discarded
because the destination address was not a local address.
Unknown Protocols Indicates the number of locally addressed datagrams that were
received successfully but discarded as result of an unknown or
unsupported protocol.
Input Discards Indicates the number of input IP datagrams that were discarded
although no problems occurred that prevented processing. One
reason for discarding these datagrams may be a lack of buffer
space. This counter does not include datagrams discarded while
awaiting reassembly.
Input Deliveries Indicates the total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).
Output Requests Indicates the total number of IP datagrams which local IP user-
protocols supplied to IP in requests for transmission. This counter
includes the ICMP user-protocol, but does not include datagrams
counted in the “Datagrams Forwarded” field.
