Abstract

   This memo defines a Management Information Base (MIB) for configuring
   and managing TN3270E servers.  TN3270E, defined by RFC 2355 [19],
   refers to the enhancements made to the Telnet 3270 (TN3270) terminal
   emulation practices.  Refer to RFC 1041 [18], STD 8, RFC 854 [16],
   and STD 31, RFC 860 [17] for a sample of what is meant by TN3270
   practices.

   The MIB defined by this memo provides generic support for both host
   and gateway TN3270E server implementations.  A TN3270E server
   connects a Telnet client performing 3270 emulation to a target SNA
   host over both a client-side network (client to TN3270E server) and
   an SNA Network (TN3270E server to target SNA host).  The client-side
   network is typically TCP/IP, but it need not be.

   A host TN3270E server refers to an implementation where the TN3270E
   server is collocated with the Systems Network Architecture (SNA)
   System Services Control Point (SSCP) for the dependent Secondary
   Logical Units (SLUs) that the server makes available to its clients
   for connecting into a SNA network.  A gateway TN3270E server resides
   on an SNA node other than an SSCP, either an SNA type 2.0 node, a
   boundary-function-attached type 2.1 node, or an APPN node acting in
   the role of a Dependent LU Requester (DLUR).  Host and gateway
   TN3270E server implementations typically differ greatly as to their
   internal implementation and system definition (SYSDEF) methods.

RFC 2561                TN3270E Using SMIv2 MIB               April 1999

   It is the intent that the MIB defined herein be extended by
   subsequent memos.  For example, one such extension enables collection
   of TN3270E response time data.

   configuration and management of TN3270E servers.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in this
