Table 59  ICMP statistics 

Statistics 

Description 

icmpInMsgs 

The total number of ICMP messages which the switch received. Note that this counter 
includes all those counted by icmpInErrors. 

icmpInErrors 

The number of ICMP messages which the switch received but determined as having 
ICMP specific errors (for example bad ICMP checksums and bad length). 

icmpInDestUnreachs 

The number of ICMP Destination Unreachable messages received. 

icmpInTimeExcds 

The number of ICMP Time Exceeded messages received. 

icmpInParmProbs 

The number of ICMP Parameter Problem messages received. 

icmpInSrcQuenchs 

The number of ICMP Source Quench (buffer almost full, stop sending data) messages 
received. 

icmpInRedirects 

The number of ICMP Redirect messages received. 

icmpInEchos 

The number of ICMP Echo (request) messages received. 

icmpInEchoReps 

The number of ICMP Echo Reply messages received. 

icmpInTimestamps 

The number of ICMP Timestamp (request) messages received. 

icmpInTimestampReps 

The number of ICMP Timestamp Reply messages received. 

icmpInAddrMasks 

The number of ICMP Address Mask Request messages received. 

icmpInAddrMaskReps 

The number of ICMP Address Mask Reply messages received. 

icmpOutMsgs 

The total number of ICMP messages which this switch attempted to send. Note that 
this counter includes all those counted by icmpOutErrors. 

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.
