Model 3120 RAS Administrators’ Reference Guide 16 • IP
# 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.
# Fragmented OK (ipFragOKs)
The number of IP datagrams that have been successfully fragmented at this entity.
# Fragmented Failed (ipFragFails)
The number of IP datagrams that have been discarded because they required fragmenting at this entity, but
were not fragmented because their Don’t Fragment option was set.
# Fragments Created (ipFragCreates)
The number of IP datagram fragments that have been generated at this entity.
# Valid but Discarded (ipRoutingDiscards)
The number of routing entries which were chosen to be discarded even though they are valid. One possible rea-
son for discarding such an entry could be to make more buffer space available for other routing entries.

The Modify IP configuration window (see figure 78) is where you can change IP forwarding and time-to-live
settings.

Forwarding (ipForwarding)
Determines whether this entity is acting as an IP gateway that will forward datagrams received by—but not
addressed to—this entity. IP gateways forward datagrams, IP hosts do not (except those source-routed via the host).
