T1/E1 DACS Administrators’ Reference Guide 10 • IP
Note The Discarded w/No Errors counter does not include any datagrams
discarded while awaiting re-assembly.
Total Deliveries (ipInDelivers)
The total number of input datagrams successfully delivered to IP user-protocols (including ICMP).
Out Requests (ipOutRequests)
The total number of IP datagrams which local IP user-protocols (including ICMP) supplied to IP in requests
for transmission.
Note The Out Requests counter does not include any datagrams counted
in ipForwDatagrams.
Out Discards (ipOutDiscards)
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 The Out Discards counter would include datagrams counted in
ipForwDatagrams if any such packets met this (discretionary) discard
criterion.
Discarded for No Routes (ipOutNoRoutes)
The number of IP datagrams discarded because no route could be found to transmit them to their destination.
Note The Discarded for No Routes counter includes any packets counted
in ipForwDatagrams which meet this “no-route” criterion. This
includes any datagrams which a host cannot route because all of its
default gateways are down.
Reassembly Timeout (ipReasmTimeout)
The maximum number of seconds which received fragments are held while they are awaiting reassembly at this
entity.
# of Reassembled Fragments (ipReasmReqds)
The number of IP fragments received which needed to be reassembled at this entity.
# Successfully Reassembled (ipReasmOKs)
The number of IP datagrams successfully reassembled.
Reassembly Failures (ipReasmFails)
The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, etc).
Note The Reassembly Failures value is not necessarily a count of discarded
IP fragments since some algorithms (notably the algorithm in
RFC 815) can lose track of the number of fragments by combining
them as they are received.
