13.2.4 TCP GROUP
This group contains statistics and control parameters for the TCP protocol. This group
contains a table describing the current TCP connections.
Note: The instances of object types that represent information about a particular TCP
connection are transient; they persist only as long as the connection in question.

Description
tcpRtoAlgorithm
Algorithm used to determine the timeout value used for
retransmitting unacknowledged octets. The cim550 uses Van
Jacobson's algorithm.
tcpRtoMin
Minimum value permitted by a TCP implementation for the
retransmission timeout. The cim550 uses a minimum timeout of
1000 milliseconds.
tcpRtoMax
Maximum value permitted by a TCP implementation for the
retransmission timeout. The cim550 uses a maximum timeout of
64000 milliseconds.
tcpMaxConn
Limit on the total number of TCP connections the entity can
support. In the cim550, the maximum number of connections is
dynamic so a value of –1 is returned.
tcpActiveOpens
Number of times TCP connections have made a direct transition to
the SYN-SENT state from the CLOSED state.
tcpPassiveOpens
Number of times TCP connections have made a direct transition to
the SYN-RCVD state from the LISTEN state.
tcpAttemptFails
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.
tcpEstabResets
Number of times TCP connections have made a direct transition to
the CLOSED state from either the ESTABLISHED state or the
CLOSE-WAIT state.
tcpCurrEstab
Number of TCP connections for which the current state is either
ESTABLISHED or CLOSE-WAIT.
tcpInSegs
Total number of segments received.
tcpOutSegs
Total number of segments sent.
tcpRetransSegs
Total number of segments retransmitted – that is, the number of
TCP segments transmitted containing one or more previously
transmitted octets.
