Table 59 ICMP statistics
Statistics Description
icmpOutErrors
The number of ICMP messages that this 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.
icmpOutDestUnreachs
The number of ICMP Destination Unreachable messages sent.
icmpOutTimeExcds
The number of ICMP Time Exceeded messages sent.
icmpOutParmProbs
The number of ICMP Parameter Problem messages sent.
icmpOutSrcQuenchs
The number of ICMP Source Quench (buffer almost full, stop sending data) messages
sent.
icmpOutRedirects
The number of ICMP Redirect messages sent.
icmpOutEchos
The number of ICMP Echo (request) messages sent.
icmpOutEchoReps
The number of ICMP Echo Reply messages sent.
icmpOutTimestamps
The number of ICMP Timestamp (request) messages sent.
icmpOutTimestampReps
The number of ICMP Timestamp Reply messages sent.
icmpOutAddrMasks
The number of ICMP Address Mask Request messages sent.
icmpOutAddrMaskReps
The number of ICMP Address Mask Reply messages sent.
