ADTRAN 1200305L1 system manual 550, and the Source-Route option processing was successful

Section 4, User Interface Guide		ATLAS 550 System Manual
	Table 6. IP Statistics (Continued)
Name	Description
FORWDATAGRAMS	The number of input datagrams for which this ATLAS 550 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 Gateways, this
	counter will include only those packets which were Source-Routed via this ATLAS
	550, and the Source-Route option processing was successful.
INUNKNOWNPROTOS	The number of locally-addressed datagrams received successfully but discarded
	because of an unknown or unsupported protocol.
INDISCARDS	The number of input IP datagrams for which no problems were encountered to
	prevent their continued processing, but which were discarded (e.g., for lack of
	buffer space). Note that this counter does not include any datagrams discarded
	while awaiting re-assembly.
INDELIVERS	The total number of input datagrams successfully delivered to IP user-protocols
	(including ICMP).
OUTREQUESTS	The total number of IP datagrams which local IP user-protocols (including ICMP)
	supplied to IP in requests for transmission. Note that this counter does not include
	any datagrams counted in FORWDATAGRAMS.
OUTDISCARDS	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
	FORWDATAGRAMS if any such packets met this (discretionary) discard criterion.
OUTNOROUTES	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
	FORWDATAGRAMS 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.
REASMTIMEOUT	The maximum number of seconds which received fragments are held while they
	are awaiting reassembly at this ATLAS 550.
REASMREQDS	The number of IP fragments received which needed to be reassembled at this
	ATLAS 550.
REASMOKS	The number of IP datagrams successfully reassembled.
REASMFAILS	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.
FRAGOKS	The number of IP datagrams that have been successfully fragmented at this
	ATLAS 550.
FRAGFAILS	The number of IP datagrams that have been discarded because they needed to be
	fragmented at this ATLAS 550 but could not be, e.g., because their “Don't
	Fragment” flag was set.
