tcpConnectionTable

A table containing information about existing TCP connections. Note that unlike earlier TCP MIBs, there is a separate table for connections in the LISTEN state.

The indexes of the table are tcpConnectionLocalAddressType, tcpConnectionLocalAddress, tcpConnectionLocalPort, tcpConnectionRemAddressType, tcpConnectionRemAddress, tcpConnectionRemPort.

Description

Implemented Specifications

1.3.6.1.2.1.6.19.1.1

tcpConnectionLocalAddressType

INTEGER{unknown(0),ipv4(1),ipv6(2),ipv4z(3),ipv6z(4),dns(16)}

not-accessible

The address type of tcpConnectionLocalAddress.

The actually supported value range is IPv4(1); IPv6(3);IPv6z(4).

Only supports IPv4(1), IPv6(3) and IPv6z(4)types

1.3.6.1.2.1.6.19.1.2

tcpConnectionLocalAddress

OCTET STRING{(0,255)}

not-accessible

The local IP address for this TCP connection. The type

of this address is determined by the value of

tcpConnectionLocalAddressType.

As this object is used in the index for the

tcpConnectionTable, implementors should be

careful not to create entries that would result in OIDs

with more than 128 subidentifiers; otherwise the information

cannot be accessed by using SNMPv1, SNMPv2c, or SNMPv3.

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

1.3.6.1.2.1.6.19.1.3

tcpConnectionLocalPort

Unsigned32{(0,65535)}

not-accessible

The local port number for this TCP connection.

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

1.3.6.1.2.1.6.19.1.4

tcpConnectionRemAddressType

INTEGER{unknown(0),ipv4(1),ipv6(2),ipv4z(3),ipv6z(4),dns(16)}

not-accessible

The address type of tcpConnectionRemAddress.

The actually supported value range is IPv4(1); IPv6(3);IPv6z(4).

Only supports IPv4(1), IPv6(3) and IPv6z(4)types

1.3.6.1.2.1.6.19.1.5

tcpConnectionRemAddress

OCTET STRING{(0,255)}

not-accessible

The remote IP address for this TCP connection. The type

of this address is determined by the value of

tcpConnectionRemAddressType.

As this object is used in the index for the

tcpConnectionTable, implementors should be

careful not to create entries that would result in OIDs

with more than 128 subidentifiers; otherwise the information

cannot be accessed by using SNMPv1, SNMPv2c, or SNMPv3.

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

1.3.6.1.2.1.6.19.1.6

tcpConnectionRemPort

Unsigned32{(0,65535)}

not-accessible

The remote port number for this TCP connection.

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

1.3.6.1.2.1.6.19.1.7

tcpConnectionState

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 state of this TCP connection.

The value listen(2) is included only for parallelism to the

old tcpConnTable and should not be used. A connection in

LISTEN state should be present in the tcpListenerTable.

The only value that 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 the TCB (as defined in [RFC793]) of

the corresponding connection on the managed node is

deleted, 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).

The actually supported access is read-only.

1.3.6.1.2.1.6.19.1.8

tcpConnectionProcess

Unsigned32

read-only

The system's process ID for the process associated with

this connection, or zero if there is no such process. This

value is expected to be the same as HOST-RESOURCES-MIB::

hrSWRunIndex or SYSAPPL-MIB::sysApplElmtRunIndex for some

row in the appropriate tables.

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

Creation Restriction

The entries in this table cannot be created.

Modification Restriction

The entries in this table cannot be modified.

Deletion Restriction

The entries in this table cannot be deleted.

Access Restriction

TCP connections must exist in the system.
