The SNMP TCPSTAT Statistics mask is displayed. The following details are displayed:
● tcpstatIndex: Unique key.
● tcpRtoAlgorithm: Algorithm used for the timeout to deal with unrecognized bytes. 2 = con-
stant re-transmission timeout, 3 = "MIL-STD-1778, Appendix B" algorithm, 4 = "Van Jacob-
son" algorithm, 1 = none of the previously mentioned algorithms.
● tcpRtoMin: Minimum value permitted for the retransmission timeout, measured in millisec-
onds.
● tcpRtoMax: Retransmission timeout, measured in milliseconds.
● tcpMaxConn: Maximum number of TCP connections supported by this network interface.
A value of -1 means that the maximum number of connections is dynamic.
● tcpActiveOpens: Number of cases in which a TCP connection switches directly from closed
status to syn-sent status.
● tcpPassiveOpens: Number of cases in which a TCP connection switches directly from lis-
ten status to syn-rcvd status.
● tcpAttemptFails: Number of cases in which a TCP connection switches directly from syn-
sent status or syn-rcvd status to closed status, and at the same time the cases in which a
TCP connection switches directly from syn-rcvd status to listen status.
● tcpEstabResets: Number of cases in which a TCP connection switches directly from es-
tablished status or from close-wait status to closed status.
● tcpCurrEstab: Number of TCP connections currently in "established" or "close-wait" status.
● tcpInSegs: Total number of segments received, including those with errors. This counter
also includes TCP connections currently open.
● tcpOutSegs: Total number of segments transmitted, including those from TCP connections
currently open. This does not include segments containing bytes that were transferred re-
peatedly.
