Description: Information about a particular current TCP connection. An object of this type is transient, in that it ceases to exist when (or soon after) the connection makes the transition to the CLOSED state.

State
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).
Enumerations:
  • closed (1)
  • listen (2)
  • synSent (3)
  • synReceived (4)
  • established (5)
  • finWait1 (6)
  • finWait2 (7)
  • closeWait (8)
  • lastAck (9)
  • closing (10)
  • timeWait (11)
  • deleteTCB (12)
LocalAddress
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.
LocalPort
The local port number for this TCP connection.
RemAddress
The remote IP address for this TCP connection.
RemPort
The remote port number for this TCP connection.
