Statistic 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 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 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.
