| MAX-ACCESS read-only |
| STATUS current |
| DESCRIPTION |
| "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 |

| described in RFC 793." |

| DESCRIPTION |
| "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." |

| received in error. This count includes segments received on |
| currently established connections." |
| ::= { tcp 10 } |
| |
| tcpOutSegs OBJECT-TYPE |
| SYNTAX Counter32 |
| MAX-ACCESS read-only |
| STATUS current |
| DESCRIPTION |

| retransmitted octets." |
| ::= { tcp 11 } |
| |
| tcpRetransSegs OBJECT-TYPE |
| SYNTAX Counter32 |
| MAX-ACCESS read-only |

| "A table containing TCP connection-specific information." |
| ::= { tcp 13 } |
| |
| tcpConnEntry OBJECT-TYPE |
| SYNTAX TcpConnEntry |
| MAX-ACCESS not-accessible |
| STATUS current |
| DESCRIPTION |
| "A conceptual row of the tcpConnTable containing information |
| about a particular current TCP connection. Each row of this |
| table is transient, in that it ceases to exist when (or soon |
| after) the connection makes the transition to the CLOSED |
| state." |

| MAX-ACCESS read-write |
| STATUS current |
| DESCRIPTION |
| "The state of this TCP connection. |
| |
| The only value which may be set by a management station is |
| deleteTCB(12). Accordingly, it is appropriate for an agent |
| to return a `badValue' response if a management station |
| attempts to set this object to any other value. |
| |
| If a management station sets this object to the value |
| deleteTCB(12), then this has the effect of deleting the TCB |
| (as defined in RFC 793) of the corresponding connection on |
| the managed node, resulting in immediate termination of the |
| connection. |
| |
| As an implementation-specific option, a RST segment may be |
| sent from the managed node to the other TCP endpoint (note |
| however that RST segments are not sent reliably)." |

| DESCRIPTION |
