POWER-ETHERNET-MIB device MIB details by RFC

POWER-ETHERNET-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.

        DESCRIPTION
              "The MIB module for managing Power Source Equipment
               (PSE) working according to the IEEE 802.af Powered
               Ethernet (DTE Power via MDI) standard.

                The following terms are used throughout this
                MIB module.  For complete formal definitions,
                the IEEE 802.3 standards should be consulted
                wherever possible:

                Group - A recommended, but optional, entity
                defined by the IEEE 802.3 management standard,
                in order to support a modular numbering scheme.
                The classical example allows an implementor to
                represent field-replaceable units as groups of
                ports, with the port numbering matching the
                modular hardware implementation.

              Port - This entity identifies the port within the group
              for which this entry contains information.  The numbering
              scheme for ports is implementation specific.

             Copyright (c) The Internet Society (2003).  This version
             of this MIB module is part of RFC 3621; See the RFC
             itself for full legal notices."
