E
RRORFREE
D
ISCARDS
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). Note that
this counter would include datagrams counted in
T
OTAL
F
ORWARDED
D
ATAGRAMS
if any such packets
met this (discretionary) discard criterion.
R
OUTELESS
D
ISCARDS
The number of IP datagrams discarded because no route could be found to transmit them to their
destination. Note that this counter includes any packets counted in
T
OTAL
F
ORWARDED
D
ATAGRAMS
which meet this “no-route” criterion. Note also that this includes any datagrams which a host cannot
route because all of its default gateways are down.
IP R
EASSEMBLY
T
IMEOUT
The maximum number of seconds received fragments are held while awaiting reassembly at this unit.
D
ISASSEMBLED
F
RAGMENTS
The number of IP fragments received which needed to be reassembled at this unit.
IP D
ATAGRAMS
R
EASSEMBLED
The number of IP datagrams successfully reassembled.
IP R
EASSEMBLY
F
AILURES
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out,
errors, etc.). Note that this is not necessarily a count of discarded IP fragments since some algorithms
(notably RFC 815s) can lose track of the number of fragments by combining them as they are
received.
S
UCCESSFUL
F
RAGMENTS
The number of IP datagrams that have been successfully fragmented at this unit.
F
AILED
F
RAGMENTS
The number of IP datagrams that have been discarded because they needed to be fragmented at this
unit but could not be (e.g., because their “Don't Fragment” flag was set).
T
OTAL
IP F
RAGMENTS
The number of IP datagram fragments that have been generated as a result of fragmentation at this
unit.
