Table 13-4 ICMP Statistics (continued)
Field | Description |
|
|
icmpOutRedirects | The number of ICMP Redirect messages sent. For a host, this object will |
| always be zero, since hosts do not send redirects. |
|
|
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. |

TCP Statistics
The following table describes the TCP statistics fields.
Table 13-5 TCP Statistics
Field | Description |
|
|
tcpRtoAlgorithm | The algorithm used to determine the timeout value used for retransmitting |
| unacknowledged octets. |
|
|
tcpRtoMin | The minimum value permitted by a TCP implementation for the retransmission |
| timeout, measured in milliseconds. More refined semantics for objects of this |
| type depend upon the algorithm used to determine the retransmission time- |
| out. In particular, when the timeout algorithm is rsre(3), an object of this |
| type has the semantics of the LBOUND quantity described in RFC 793. |
|
|
tcpRtoMax | The maximum value permitted by a TCP implementation for the retransmission |
| timeout, measured in milliseconds. More refined semantics for objects of this |
| type depend upon the algorithm used to determine the retransmission time- |
| out. In particular, when the timeout algorithm is rsre(3), an object of this |
| type has the semantics of the UBOUND quantity described in RFC 793. |
|
|
tcpMaxConn | The limit on the total number of TCP connections the entity (the switch) can sup- |
| port. In entities where the maximum number of connections is dynamic, this |
| object should contain the value |
|
|
tcpActiveOpens | The number of times TCP connections have made a direct transition to the SYN- |
| SENT state from the CLOSED state. |
|
|
tcpPassiveOpens | The number of times TCP connections have made a direct transition to the SYN- |
| RCVD state from the LISTEN state. |
