PoE switch comes with network management function?

Power over Ethernet (PoE) is approved in June 2003 by the IEEE 802.3af standard power supply technology, it uses the existing network 5 (CAT-5) data transmission cable DC power transmission in the signal also transmit the power supply to the electric equipment (PD), such as AP, IP and wireless telephone network cameras, eliminating the local power supply. In PoE system, the power supply device for PD is called power supply equipment (PSE).

The PoE switch is a switch that can be powered by a network cable, which is used instead of an ordinary switch and does not need to pull the power line. With it, wireless AP, IP phones, network cameras and other terminal equipment can easily achieve power supply, and more beautiful and safe and convenient.

The switch network, and non network, with network function switches provide terminal control based on (Console), based on the Web page and support remote login Telnet network and other network management.

So the network administrator can monitor the working status of the switch and the network operation in a local or remote way. The network switches support SNMP protocol, SNMP protocol consists of a set of simple network communication specification, can complete all the basic tasks of network management, the cyber source demand less, have some security mechanisms. The working mechanism of the SNMP protocol is very simple, mainly through a variety of different types of messages, that is, PDU (protocol data unit) to achieve network information exchange.

There is also a network management switch providing policy based QoS (Quality of service). The switch control strategy is that the rules of behavior, network administrators use strategy of streaming bandwidth assignment, application priority and control network access, the key is to meet the bandwidth management strategy for service level agreements and strategies to release switch. At each port switch used to represent the multifunctional port state, half duplex full duplex / 10BaseT / 100BaseT and the light emitting diode (LED) and redundant power system (RPS), and state level LED exchange bandwidth utilization form a comprehensive and convenient visual management system. At present, most of the following switches are mostly non network management, only the enterprise level and a small number of switches to support network management functions.

With the network management function of the PoE switch compared to non network PoE switch, more than the above functions, and network management PoE switches than non network management to your point.
