  • Page 63 Chapter 4: Web configuration If switch A broadcasts a packet to switch B, switch B broadcasts to switch C, and switch C broadcasts back to switch A and so on. The broadcast packet will be passed indefinitely in a loop, potentially causing a network failure. In this example, STP breaks the loop by blocking the connection between switch B and C.
  • Page 64 Chapter 4: Web configuration The switch with the lowest bridge ID (switch C) was elected the root bridge, and the ports were selected to give a high port cost between switches B and C.

    Chapter 5: Switch operation Chapter 5 Switch operation Address table The switch is implemented with an address table. This address table is composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port number, etc. This information comes from the learning process of the managed switch.

  • Page 86: Auto-Negotiation

    Chapter 5: Switch operation transmission. Therefore, no erroneous packets will occur, making it the best choice when a network needs efficiency and stability. The switch scans the destination address from the packet header and searches the routing table provided for the incoming port and forwards the packet if required. The fast forwarding makes the switch attractive for connecting servers directly to the network, thereby increasing throughput and availability.

  • Page 87: Poe Overview

    Chapter 6 PoE overview What is PoE? PoE is an abbreviation for Power over Ethernet. PoE technology permits a system to pass data and electrical power safely on an Ethernet UTP cable. The IEEE standard for PoE technology requires a category 5 cable or higher for high power PoE levels, but can operate with a category 3 cable for low power levels.
  • Page 88 Chapter 6: PoE overview 15.40 W. A later specification, IEEE 802.3at, offers 25.50 W. When the device is a switch, it is commonly called an end-span, although IEEE 802.3af refers to it as endpoint. Otherwise, if it's an intermediary device between a non PoE capable switch and a PoE device, it's called a mid-span.
  • Page 89 Chapter 7 Troubleshooting This chapter contains information to help you solve issues.
