Description
The algorithm used to determine the timeout value used for retransmitting
unacknowledged octets.
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 Request For Comments (RFC) 793.
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.
The limit on the total number of TCP connections the switch can support. In entities
where the maximum number of connections is dynamic, this object should contain the
value -1.
The number of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state.
The number of times TCP connections have made a direct transition to the SYN-RCVD
state from the LISTEN state.
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.
The number of times TCP connections have made a direct transition to the CLOSED
state from either the ESTABLISHED state or the CLOSE- WAIT state.
The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
The total number of segments sent, including those on current connections but
excluding those containing only retransmitted octets.
The total number of segments retransmitted, that is, the number of TCP segments
transmitted containing one or more previously transmitted octets.
