ICMP statistics are described in the following table:
Table 53
ICMP Statistics
Statistic Description
icmpInMsgs
The total number of ICMP messages which the entity (the switch) received. Note
that this counter includes all those counted by icmpInErrors.
icmpOutMsgs
The total number of ICMP messages which this entity (the switch) attempted to send.
Note that this counter includes all those counted by icmpOutErrors.
icmpInErrors
The number of ICMP messages that the entity (the switch) received but determined
as having ICMP-specific errors (bad ICMP checksums, bad length, and so forth).
icmpOutErrors
The number of ICMP messages which this entity (the switch) did not send due to
problems discovered within ICMP such as a lack of buffer. This value should not
include errors discovered outside the ICMP layer such as the inability of IP to route
the resultant datagram.
In some implementations there may be no types of errors that contribute to this
counter’s value.
icmpInDestUnreachs
The number of ICMP Destination Unreachable messages received.
icmpOutDestUnreachs
The number of ICMP Destination Unreachable messages sent.
icmpInTimeExcds
The number of ICMP Time Exceeded messages received.
icmpOutTimeExcds
The number of ICMP Time Exceeded messages sent.
icmpInParmProbs
The number of ICMP Parameter Problem messages received.
icmpOutParmProbs
The number of ICMP Parameter Problem messages sent.
icmpInSrcQuenchs
The number of ICMP Source Quench (buffer almost full, stop sending data)
messages received.
icmpOutSrcQuenchs
The number of ICMP Source Quench (buffer almost full, stop sending data)
messages sent.
icmpInRedirects
The number of ICMP Redirect messages received.
icmpOutRedirects
The number of ICMP Redirect messages sent. For a host, this object will always be
zero, since hosts do not send redirects.
icmpInEchos
The number of ICMP Echo (request) messages received.
icmpOutEchos
The number of ICMP Echo (request) messages sent.
icmpInEchoReps
The number of ICMP Echo Reply messages received.
icmpOutEchoReps
The number of ICMP Echo Reply messages sent.
icmpInTimestamps
The number of ICMP Timestamp (request) messages received.
icmpOutTimestamps The
number of ICMP Timestamp (request) messages sent.
icmpInTimestampReps The
number of ICMP Timestamp Reply
messages received.
icmpOutTimestampReps The
number of ICMP Timestamp Reply
messages sent.
icmpInAddrMasks
The number of ICMP Address Mask Request messages received.
icmpOutAddrMasks
The number of ICMP Address Mask Request messages sent.
icmpInAddrMaskReps
The number of ICMP Address Mask Reply messages received.
