	sent.

The following table describes the Transmission Control Protocol (TCP) statistics:

Table 44 TCP statistics

Statistics	Description
tcpRtoAlgorithm	The algorithm used to determine the timeout value used for retransmitting
	unacknowledged octets.
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 Request For Comments (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.
tcpMaxConn	The limit on the total number of TCP connections the switch can support. In entities
	where the maximum number of connections is dynamic, this object should contain
	the value -1.
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 SYN-RCVD 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.
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.
