tcpRtoAlgorithm (1) RO
The algorithm used to determine the timeout value
for resending.
Other (1): Other than the following items.
Constant (2): A constant RTO value.
Rsre (3): The algorithm specified by the MIL-
STD-1778 standard.
Vanj (4): The Van Jacobson algorithm.
Sup-
ported.
According to the
standard.
tcpRtoMin (2) RO
The minimum resend timeout value (in 0.01 s).
This value depends on the algorithm used to
determine the resend timeout value.
Sup-
ported.
According to the
standard.
tcpRtoMax (3) RO
The maximum resend timeout value (in 0.01 s).
This value depends on the algorithm used to
determine the resend timeout value.

If the maximum number of connections is
dynamic, this value is
−
1.

changed from the CLOSE state directly to the
SYN-SENT state. (Active connection establish-
ment.)

ported.
According to the
standard.
tcpPassiveOpens (6) RO
The number of times the TCP connection
changed from the LISTEN state directly to the
SYN-RCVD state. (Passive connection establish-
ment.)
Sup-
ported.
According to the
standard.
tcpAttemptFails (7) RO

changed from the SYN-SENT or SYN-RCVD state
directly to the CLOSE state and from the SYN-
RCVD state directly to the LISTEN state.

changed from the ESTABLISHED or the CLOSE-
WAIT state directly to the CLOSE state.

includes the number of error segments.
Sup-
ported.
According to the
standard.
tcpOutSegs (11) RO

the number of segments for the current connec-
tion, but does not include the number of segments
for resent data only.
