Datagrams Forwarded
The number of input datagrams for which this entity 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. 
Reassembly Required
The number of IP fragments received which needed to be reassembled at 
this entity.
Reassembly Failures
The number of failures detected by the IP re-assembly algorithm (for 
whatever reason: timed out, errors, etc.). 
Datagrams Failing 
Fragmentation
The number of datagrams that have been discarded because they needed 
to be fragmented at this entity but could not be, e.g., because their “Don't 
Fragment” flag was set.
Received Header Errors
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, etc.
Unknown Protocols Received
The number of locally-addressed datagrams received successfully but 
discarded because of an unknown or unsupported protocol.
Received Packets Delivered
The total number of input datagrams successfully delivered to IP 
user-protocols (including ICMP).
Discarded Output Packets
The number of output IP datagrams for which no problem was 
encountered to prevent their transmission to their destination, but which 
were discarded (e.g., for lack of buffer space). 
Fragments Created
The number of datagram fragments that have been generated as a result 
of fragmentation at this entity.
Routing Discards
The number of routing entries which were chosen to be discarded even 
though they are valid. One possible reason for discarding such an entry 
could be to free-up buffer space for other routing entries.
Reassembly Successful
The number of datagrams successfully re-assembled.
Datagrams Successfully 
Fragmented
The number of IP datagrams that have been successfully fragmented at 
this entity.
