Description
The number of IP datagram fragments that have been generated as
a result of fragmentation at this entity.
The number of IP fragments received that needed to be
reassembled at this entity.
The number of IP datagrams successfully reassembled.
The number of failures detected by the IP reassembly algorithm (for
whatever reason: timed out, errors, and so on). Note that this
number is not necessarily a count of discarded IP fragments
because some algorithms (notably the algorithm in RFC 815) can
lose track of the number of fragments by combining them as they
are received.
From the Device Manager menu bar, choose Graph > Chassis.
The graphChassis dialog box opens with the SNMP In tab displayed.
Click the ICMP In tab.
The ICMP In tab opens (Figure 82 on page 199).
