tcpConnTable

table deprecated
.1.3.6.1.2.1.6.13 · 1 row entry · 5 columns
Open in standard view 
A table containing information about existing IPv4-specific
TCP connections or listeners.  This table has been
deprecated in favor of the version neutral
tcpConnectionTable.
tcpConnEntry entry .1.3.6.1.2.1.6.13.1
A conceptual row of the tcpConnTable containing information
about a particular current IPv4 TCP connection. Each row
of this table is transient in that it ceases to exist when
(or soon after) the connection makes the t…

The state of this TCP connection.

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 stat…

of a connection in the listen state willing to

tcpListenerTable

table
.1.3.6.1.2.1.6.20 · 1 row entry · 4 columns
Open in standard view 
A table containing information about TCP listeners.  A
listening application can be represented in three
possible ways:
          
1. An application that is willing to accept both IPv4 and
   IPv6 datagrams is represented by
          
   a tcpListenerLocalAddressType of unknown (0) and
   a tcpListenerLocalAddress of ''h (a zero-length
   octet-string).
          
2. An application that is willing to accept only IPv4 or
   IPv6 datagrams is represented by a
   tcpListenerLocalAddressType of the appropriate address
   type and a tcpListenerLocalAddress of '0.0.0.0' or '::'
   respectively.
          
3. An application that is listening for data destined
   only to a specific IP address, but from any remote
   system, is represented by a tcpListenerLocalAddressType
   of an appropriate address type, with
   tcpListenerLocalAddress as the specific local address.
          
NOTE: The address type in this table represents the
address type used for the communication, irrespective
of the higher-layer abstraction.  For example, an
application using IPv6 'sockets' to communicate via
IPv4 between ::ffff:10.0.0.1 and ::ffff:10.0.0.2 would
use InetAddressType ipv4(1)).
