ICMP Statistics
Internet Control Message Protocol (ICMP) is a network layer protocol that transmits
message packets to report errors in processing IP packets. ICMP is therefore an
integral part of the Internet Protocol. ICMP messages may be used to report various
situations, such as when a datagram cannot reach its destination, when the gateway
does not have the buffering capacity to forward a datagram, and when the gateway
can direct the host to send traffic on a shorter route. ICMP is also used by routers to
feed back information about more suitable routes (i.e., the next hop router) to use for
a specific destination.
Routing Discards
The number of routing entries which were chosen to be discarded even
though they are valid. One possible reason for discarding such an entry
could be to free-up buffer space for other routing entries.
Reassembly Successful
The number of datagrams successfully re-assembled.
Datagrams Successfully
Fragmented
The number of IP datagrams that have been successfully fragmented at
this entity.

Parameter
Description
Messages
The total number of ICMP messages which the entity received/sent.
Errors
The number of ICMP messages which the entity received/sent but
determined as having ICMP-specific errors (bad ICMP checksums, bad
length, etc.).
