CTRON-ROUTERS-INTERNAL-MIB by vendor Enterasys Networks Inc


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.

--  This module provides authoritative definitions for Cabletron's
--  enterprise specific Routing Services MIB.  This MIB contains
--  objects which provide a high-level view of the routed and routing
--  protocols for the Cabletron Router.  Essentially, this MIB
--  allows for the dynamic "discovery" of routing services within
--  Cabletron devices.

--  This module will be extended, as needed.

--  Cabletron Systems reserves the right to make changes in
--  specifications 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.
