			Table 9-2. ICMP Statistics (Continued)

	Name		Description

	OutRedirects		The number of ICMP Redirect messages sent.

	OutEchos		The number of ICMP Echo (request) messages sent.

	OutEchoReps		The number of ICMP Echo Reply messages sent.

	OutTimestamps		The number of ICMP Timestamp (request) messages sent.

	OutTimestampReps		The number of ICMP Timestamp Reply messages sent.

	OutAddrMasks		The number of ICMP Address Mask Request messages sent.

	OutAddrMaskReps		The number of ICMP Address Mask Reply messages sent.

	Clear		Clears the accumulated statistics.

TCP			Table 9-3 describes the TCP statistics.

	Name		Description

	RtoAlgorithm	The algorithm used to determine the timeout value used for retransmitting
		unacknowledged octets.

	RtoMin	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.

	RtoMax	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.

	MaxConn	The limit on the total number of TCP connections the ATLAS 550 can support.
		In entities where the maximum number of connections is dynamic, this object
		should contain the value “-1.”

	ActiveOpens	The number of times TCP connections have made a direct transition to the
		SYN-SENT state from the CLOSED state.

	PassiveOpens	The number of times TCP connections have made a direct transition to the
		SYN-RCVD state from the LISTEN state.

	AttemptFails	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.
