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. |
