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.
