- SYNTAX Integer32
- UNITS "milliseconds"
- 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
- of this type has the semantics of the LBOUND quantity
- 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

-
- 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

- 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)."
