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