2 TCP Group TCP Group Implementation of the TCP group is mandatory for all systems that implement the TCP. Instances of object types that represent information about a particular TCP connection are transient; they persist only as long as the connection in question. tcpRtoAlgorithm 1.3.6.1.2.1.6.1 The algorithm used to determine the time-out value used for retransmitting unacknowledged octets. tcpRtoMin 1.3.6.1.2.1.6.2 The minimum value permitted by a TCP implementation for the retransmission time-out, 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 time-out algorithm is 3 (rsre), an object of this type has the semantics of the LBOUND quantity described in RFC 793. tcpRtoMax 1.3.6.1.2.1.6.3 The maximum value permitted by a TCP implementation for the retransmission time-out, 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 time-out algorithm is 3 (rsre), an object of this type has the semantics of the UBOUND quantity described in RFC 793. tcpMaxConn 1.3.6.1.2.1.6.4 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. tcpActiveOpens 1.3.6.1.2.1.6.5 The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state. tcpPassiveOpens 1.3.6.1.2.1.6.6 The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state. 36 Fabric OS MIB Reference 53-1000439-01
