Source: RFC 2012
| Object | Description |
|---|---|
| RtoAlgorithm | The algorithm used to determine the timeout value used for retransmitting unacknowledged octets. |
| RtoMin | 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 timeout. 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. |
| RtoMax | 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 timeout. 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. |
| MaxConn | The limit on the total number of TCP connections the entity can support. In entities where the maximum number of connections is dynamic, this object should contain the value -1. |
| ActiveOpens | The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state. |
| PassiveOpens | The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state. |
| AttemptFails | The number of times TCP connections have made a direct transition to the CLOSED state from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state. |
| EstabResets | The number of times TCP connections have made a direct transition to the CLOSED state from either the ESTABLISHED state or the CLOSE-WAIT state. |
| CurrEstab | The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. |
| InSegs | The total number of segments received, including those received in error. This count includes segments received on currently established connections. |
| OutSegs | The total number of segments sent, including those on current connections but excluding those containing only retransmitted octets. |
| RetransSegs | The total number of segments retransmitted - that is, the number of TCP segments transmitted containing one or more previously transmitted octets. |
| ConnTable | A table containing TCP connection-specific information. |
| InErrs | The total number of segments received in error (for example, bad TCP checksums). |
| OutRsts | The number of TCP segments sent containing the RST flag. |
