TCP Table 9-3 describes the TCP statistics.
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.

Table 9-3. 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.
