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.
Sup-
ported.
According to the
standard.
tcpMaxConn
(4) RO
The total number of supported TCP connections.
If the maximum number of connections is
dynamic, this value is
−
1.
Sup-
ported.
According to the
standard.
tcpActiveOpens
(5) RO
The number of times the TCP connection
changed from the CLOSE state directly to the
SYN-SENT state. (Active connection establish-
ment.)
Sup-
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
The total number of times the TCP connection
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.
Sup-
ported.
According to the
standard.
tcpEstabResets
(8) RO
The number of times the TCP connection
changed from the ESTABLISHED or the CLOSE-
WAIT state directly to the CLOSE state.
Sup-
ported.
According to the
standard.
tcpCurrEstab
(9) RO
The total number of TCP connections currently in
the ESTABLISHED or the CLOSE-WAIT state.
Sup-
ported.
According to the
standard.
tcpInSegs
(10) RO
The total number of received segments. This
includes the number of error segments.
Sup-
ported.
According to the
standard.
tcpOutSegs
(11) RO
The total number of sent segments. This includes
the number of segments for the current connec-
tion, but does not include the number of segments
for resent data only.
Sup-
ported.
According to the
standard.
tcpRetransSegs
(12) RO
The total number of resent segments.
Sup-
ported.
According to the
standard.
