The total number of segments sent, including those on current connections, but excluding those containing only retransmitted octets. The algorithm used to determine the timeout value used for retransmitting unacknowledged octets. The limit on the total number of TCP connections the entity (the switch) can support.

TCP statistics are described in the following table:
Table 87
TCP Statistics
Statistic
Description
tcpInSegs
The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
tcpOutSegs
The total number of segments sent, including those on current connections, but excluding
those containing only retransmitted octets.
tcpRtoAlgorithm
The algorithm used to determine the timeout value used for retransmitting
unacknowledged octets.
tcpMaxConn
The limit on the total number of TCP connections the entity (the switch) can support. In
entities where the maximum number of connections is dynamic, this object should
contain the value -1.
tcpRtoMin
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.
tcpRtoMax
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.
tcpActiveOpens
The number of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state.
tcpPassiveOpens
The number of times TCP connections have made a direct transition to the SYN-RCVD
state from the LISTEN state.
tcpAttemptFails
The number of times TCP connections have made a direct transition to the CLOSED state
from either the SYN-SENT state or the SYNRCVD state, plus the number of times TCP
connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
tcpEstabResets
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.
tcpRetransSegs
The total number of segments retransmitted - that is, the number of TCP segments
transmitted containing one or more previously transmitted octets.
tcpInErrs
The total number of segments received in error (for example, bad TCP
checksum
s
).
tcpCurBuff
The total number of outstanding memory allocations from heap by TCP protocol stack.
tcpCurConn
The total number of outstanding TCP sessions that are currently opened.
tcpOutRsts
The number of TCP segments sent containing the RST flag.
All TCP allocated control blocks
Destinate Address
Switch IP address of TCP connections.
Remote Port
TCP port used by the remote device.
Source Address
IP address of TCP source connections.
Local Port
Available TCP ports used for connecting to the switch.
State
State of each TCP connection.
