CTRON-NAT-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

CTRON-NAT-MIB DEFINITIONS ::= BEGIN -- ctron-nat-mib.txt Cabletron Network Address Translator MIB. -- Revision: 01.00.00 -- Part Number: -- Date: December 16, 1998 -- Cabletron Systems, Inc. -- 35 Industrial Way, P.O. Box 5005 -- Rochester, NH 03866-5005 -- (603) 332-9400 -- support@ctron.com -- This module provides authoritative definitions for part -- of the naming tree below: -- -- cabletron { enterprises 52 } -- -- This module will be extended, as additional sub-sections -- of this naming tree are defined. -- -- Cabletron Systems reserves the right to make changes in -- specification and other information contained in this document -- without prior notice. The reader should consult Cabletron Systems -- to determine whether any such changes have been made. -- -- In no event shall Cabletron Systems be liable for any incidental, -- indirect, special, or consequential damages whatsoever (including -- but not limited to lost profits) arising out of or related to this -- document or the information contained in it, even if Cabletron -- Systems has been advised of, known, or should have known, the -- possibility of such damages. -- -- Cabletron grants vendors, end-users, and other interested parties -- a non-exclusive license to use this Specification in connection -- with the management of Cabletron products. -- -- Copyright August 1997 Cabletron Systems -- Abstract -- -- This memo defines management objects which are required to support -- Cabletron's implementation of RFC 1631, The IP Network Address -- Translator (NAT). -- Structure of MIB -- -- Objects, in this MIB, are arranged into groups. Each group is organized -- as a set of related objects and is described below. -- The ctNatConfigGroup Group -- -- This group contains the objects that are specific to the configuration, -- control and status of network address translation functionality. All of -- the read-write objects are persistent. "Private" refers to a network -- which uses IP addresses which must be translated. Devices on that -- network are termed "Local". Their IP addresses are not official, and -- they cannot be accessed from external networks without NAT. "Public" -- refers to the networks outside the private area which use registered -- IP addresses. It is also called the "Internet". Devices on the internet -- can be also termed "Foreign". -- The ctNatServerGroup Group -- -- This group contains the objects that are specific to the server -- list. The list contains information describing the assignment -- of devices on the private network to perform some server functions. -- The assignment will make the device accessible to the public network. -- Access is obtained by addressing the Internet IP and a predefined port. -- The ctNatConnStatsGroup Group -- -- This group contains the objects that are specific to the client list. -- The list contains information describing some statistics -- which are collected for ACTIVE connections. The data are deleted -- when the connection goes inactive.
