CISCO-POE-PD-MIB device MIB details by Cisco

CISCO-POE-PD-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
                "This MIB is intended for devices powered by 
                external power sources, in particular Power 
                Over Ethernet (PoE or formerly called inline 
                power), to provide power usage configuration 
                and information for NMS.  For example, PoE 
                supplies DC power over standard Category 5 
                unshielded twisted-pair (UTP) cable.  Instead 
                of requiring wall power, powered devices such 
                as IP telephones can utilize power provided
                from power source equipments.  By using Cisco
                Discovery Protocol (CDP),  powered devices 
                can negotiated with power source equipment to
                obtain optimum power supply. 
                  
                 
                                  GLOSSARY

                Midspan Injector
                    The midspan PSE sends out a signal tone down
                    one of the unused pairs of the standard 
                    Category 5 cable and detects tone on the 
                    other unused pair when the PD loops this tone
                    back to it through a loopback transformer.  
                    Once the midspan PSE detects this tone, it 
                    begins to provide power down the cable using 
                    the unused pairs.  The midspan PSE provide no 
                    physical layer capability. 

                Powered Device ( PD )
                    These are devices powered by external electrical
                    power sources.  They are, for example, IP 
                    telephones and wireless Access Points or bridges. 

                Power Source Equipment ( PSE )
                    These are devices supplying electrical power to  
                    other equipments.  They are, for example, inline 
                    power switches and power patch panels."
