Statistics	Description
tcpRtoAlgorithm	The algorithm used to determine the timeout value used for retransmit-
	ting unacknowledged octets.
tcpRtoMin	The minimum value permitted by a TCP implementation for the retrans-
	mission 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 retrans-
	mission 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 entity (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 tran-
	sition to the LISTEN state from the SYN-RCVD state.
