Scalar details
tcpRtoMin
1.3.6.1.2.1.6.2
Integer32 · milliseconds
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
1.3.6.1.2.1.6.3
Integer32 · milliseconds
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
1.3.6.1.2.1.6.4
Integer32
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.
tcpActiveOpens
1.3.6.1.2.1.6.5
Counter32
The number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
tcpPassiveOpens
1.3.6.1.2.1.6.6
Counter32
The number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
tcpAttemptFails
1.3.6.1.2.1.6.7
Counter32
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.
tcpEstabResets
1.3.6.1.2.1.6.8
Counter32
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.
tcpCurrEstab
1.3.6.1.2.1.6.9
Gauge32
The number of TCP connections for which the current state is either ESTABLISHED or CLOSE- WAIT.
tcpInSegs
1.3.6.1.2.1.6.10
Counter32
The total number of segments received, including those received in error. This count includes segments received on currently established connections.
tcpOutSegs
1.3.6.1.2.1.6.11
Counter32
The total number of segments sent, including those on current connections but excluding those containing only retransmitted octets.
tcpRetransSegs
1.3.6.1.2.1.6.12
Counter32
The total number of segments retransmitted - that is, the number of TCP segments transmitted containing one or more previously transmitted octets.
tcpInErrs
1.3.6.1.2.1.6.14
Counter32
The total number of segments received in error (e.g., bad TCP checksums).
tcpOutRsts
1.3.6.1.2.1.6.15
Counter32
The number of TCP segments sent containing the RST flag.
Table details
tcpConnTable
1.3.6.1.2.1.6.13
Index: tcpConnLocalAddress · tcpConnLocalPort · tcpConnRemAddress · tcpConnRemPort
A table containing TCP connection-specific information.
tcpConnState
1.3.6.1.2.1.6.13.1.1
INTEGER1 = closed2 = listen3 = synSent4 = synReceived5 = established6 = finWait17 = finWait28 = closeWait9 = lastAck10 = closing11 = timeWait12 = deleteTCB · Integer32
The state of this TCP connection. The only value which may be set by a management station is deleteTCB(12). Accordingly, it is appropriate for an agent to return a `badValue' response if a management station attempts to set this object to any other value. If a management station sets this object to the value deleteTCB(12), then this has the effect of deleting the TCB (as defined in RFC 793) of the corresponding connection on the managed node, resulting in immediate termination of the connection. As an implementation-specific option, a RST segment may be sent from the managed node to the other TCP endpoint (note however that RST segments are not sent reliably).
tcpConnLocalAddress
1.3.6.1.2.1.6.13.1.2
IpAddress SIZE (4)
The local IP address for this TCP connection. In the case of a connection in the listen state which is willing to accept connections for any IP interface associated with the node, the value 0.0.0.0 is used.
tcpConnLocalPort
1.3.6.1.2.1.6.13.1.3
INTEGER (0..65535) · Integer32
The local port number for this TCP connection.
tcpConnRemAddress
1.3.6.1.2.1.6.13.1.4
IpAddress SIZE (4)
The remote IP address for this TCP connection.
tcpConnRemPort
1.3.6.1.2.1.6.13.1.5
INTEGER (0..65535) · Integer32
The remote port number for this TCP connection.
