CTRMONXT-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.

-- 1.  Status of this Memo

-- This draft document is an internal Cabletron document
-- for experimental use.  Please send comments to the Bill 
-- Fardy (fardy@ctron.com) or Jason Nyberg (nyberg@ctron.com).


-- 2.  Abstract

-- This memo defines a entrprise specific, Cabletron extensions
-- to the RMON MIB (RFC 1271) use with network management
-- protocols in TCP/IP-based internets.  In particular, it
-- defines objects for managing remote network monitoring
-- devices tha tare not already identified in RFC1271.


-- 3  Format of Definitions

-- Section 7 contains the specification of all object types
-- contained in this MIB module.  The object types are defined
-- using the conventions defined in the SMI, as amended by the
-- extensions specified in [9,10].

-- 4.  Overview

-- RFC 1271 described a set of objects that would provide information
-- that would help a manager identify the performance and behavior
-- of a network segment.  This document extends that by specifying
-- more specific objects that allow even greater detail into the
-- performance and behavior of a network segment.  Unless specified, 
-- these extensions do not require the objects in the RMON MIB
-- to be present.
-- 
-- 
-- 5.  Structure of MIB

-- The objects are arranged into the following groups:

--         - Discovery

--   These groups are the basic unit of conformance.  If a remote
-- monitoring device implements a group, then it must implement
-- all objects in that group.

-- All groups in this MIB are optional.  Implementations of this
-- MIB must also implement the system and interfaces group of
-- MIB-II [6].  MIB-II may also mandate the implementation of
-- additional groups.

-- These groups are defined to provide a means of assigning
-- object identifiers, and to provide a method for managed agents
-- to know which objects they must implement.

-- 5.1.  The Discovery Group

-- The Discovery Group contains information statistics measured by
-- the probe for each monitored interface on this device.  This group
-- currently consists of the ctDiscoveryTable that is intended for
-- discovery purposes.  In the future it may be expanded.
--
