Description
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.
The total number of segments received in error (for example, bad TCP
checksums).
The total number of outstanding memory allocations from heap by TCP protocol
stack.
The total number of outstanding TCP sessions that are currently opened.
The number of TCP segments sent containing the reset (RST) flag.
