tcpConnTable

tcpConnTable

tcpConnTable stores the information about all IPv4 TCP listeners, connection interfaces, and endpoints that can receive data packets or connection requests. This table contains five objects: tcpConnState, tcpConnLocalAddress, tcpConnLocalPort, tcpConnRemAddress, and tcpConnRemPort.

The indexes of this table are tcpConnLocalAddress, tcpConnLocalPort, tcpConnRemAddress, and tcpConnRemPort.

tcpConnState

INTEGER{

closed(1),

listen(2),

synSent(3),

synReceived(4),

established(5),

finWait1(6),

finWait2(7),

closeWait(8),

lastAck(9),

closing(10),

timeWait(11),

deleteTCB(12)

}

Read-write

The value of this object identifies the status 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 object, resulting in immediate termination of the connection.

As an implementation-specific option, an RST segment may be sent from the managed node to the other TCP endpoint (note however that RST segments are not sent reliably).

Currently, the supported maximum access is read-only.

1.3.6.1.2.1.6.13.1.2

tcpConnLocalAddress

IpAddress

Read-only

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 object, the value 0.0.0.0 is used.

This object is implemented as defined in the corresponding MIB file.

1.3.6.1.2.1.6.13.1.3

tcpConnLocalPort

INTEGER (0...65535)

Read-only

The local port number for this TCP connection.

This object is implemented as defined in the corresponding MIB file.

1.3.6.1.2.1.6.13.1.4

tcpConnRemAddress

IpAddress

Read-only

The remote IP address for this TCP connection.

This object is implemented as defined in the corresponding MIB file.

1.3.6.1.2.1.6.13.1.5

tcpConnRemPort

INTEGER (0...65535)

Read-only

The remote port number for this TCP connection.

This object is implemented as defined in the corresponding MIB file.

Creation Restriction

The entries in this table cannot be created.

Modification Restriction

The only value that the management process can set to the tcpConnTable is 12 (For example, terminate the connection immediately).

Deletion Restriction

The entries in this table cannot be deleted.

Access Restriction

None.
