Maximum Connections (tcpMaxConn)

The limit on the total number of TCP connections the entity can support. In entities where the maximum number of connections is dynamic, this object should contain the value -1.

Active Opens (tcpActiveOpens)

The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.

Passive Opens (tcpPassiveOpens)

The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LIS- TEN state.

Attempt/Fails (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 transition to the LISTEN state from the SYN-RCVD state.

ESTABLISHED Resets (tcpEstabResets)

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.

Current ESTABLISHED (tcpCurrEstab)

The number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.

Total Received (tcpInSegs)

The total number of segments received, including those received in error. This count includes segments received on currently established connections.

Total Sent (tcpOutSegs)

The total number of segments sent, including those on current connections but excluding those containing only retransmitted octets.

Total Retransmitted (tcpRetransSegs)

The total number of segments retransmitted—that is, the number of TCP segments transmitted containing one or more previously transmitted octets.

Total Received in Error (tcpInErrs)

The total number of segments received in error (e.g., bad TCP checksums).

Total Sent w/RST Flag (tcpOutRsts)

The number of TCP segments sent containing the RST ﬂag.
