RtoAlgorithm
The algorithm used to determine the timeout value used for retransmitting unacknowledged octets. other(1) none of the following constant(2) a constant rto rsre(3) MIL-STD-1778, Appendix B vanj(4) Van Jacobson's algorithm [5] Enumerations: other (1) constant (2) rsre (3) vanj (4)
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.
InErrs
The total number of segments received in error (e.g., bad TCP checksums).
OutRsts
The number of TCP segments sent containing the RST flag.
