User’s Manual of GS-5220 PoE Series Managed Switch 3. SWITCH MANAGEMENT This chapter explains the methods that you can use to configure management access to the Managed Switch. It describes the types of management applications and the communication and management protocols that deliver data between your management device (workstation or personal computer) and the system. It also contains information about port connection options.
PAGE 56
User’s Manual of GS-5220 PoE Series Managed Switch 3.2 Management Access Overview The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:  An administration console  Web browser interface  An external SNMP-based network management application The administration console and Web browser interface support are embedded in the Managed Switch software and are available for immediate use. Each of these management methods has their own advantages.
PAGE 57
User’s Manual of GS-5220 PoE Series Managed Switch 3.3 Administration Console The administration console is an internal, character-oriented, and command line user interface for performing system administration such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal, personal computer, Apple Macintosh, or workstation connected to the Managed Switch's console (serial) port.
PAGE 58
User’s Manual of GS-5220 PoE Series Managed Switch You can change these settings, if desired, after you log on. This management method is often preferred because you can remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any terminal-emulation program for connecting to the terminal serial port.
PAGE 59
User’s Manual of GS-5220 PoE Series Managed Switch 3.5 SNMP-based Network Management You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMP Network Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP agent on the switch and the SNMP Network Management Station to use the same community string.

User’s Manual of GS-5220 PoE Series Managed Switch 4.3.3.2 IEEE 802.1Q VLAN In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Managed Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This also provides a more secure and cleaner network environment.

User’s Manual of GS-5220 PoE Series Managed Switch ■ 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
PAGE 136
User’s Manual of GS-5220 PoE Series Managed Switch Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN are defined on the switch, all ports are then assigned to a default VLAN with a PVID equal to 1. Untagged packets are assigned the PVID of the port on which they were received. Forwarding decisions are based upon this PVID, in so far as VLAN are concerned. Tagged packets are forwarded according to the VID contained within the tag.

User’s Manual of GS-5220 PoE Series Managed Switch ■ Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by enabled routing on this switch. ■ Untagged VLANs Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security.

This allows the switch to interact with other bridging devices in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
PAGE 160
User’s Manual of GS-5220 PoE Series Managed Switch  The port identifier of the transmitting port The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch uses the information in the frame to calculate a BPDU, and, if the topology changes, initiates a BPDU transmission.

User’s Manual of GS-5220 PoE Series Managed Switch 5. SWITCH OPERATION 5.1 Address Table The Managed 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 nodes in the network, including MAC address, port no, etc. This information comes from the learning process of Managed Switch. 5.2 Learning When one packet comes in from any port, the Managed Switch will record the source address, port no.

User’s Manual of GS-5220 PoE Series Managed Switch 5.5 Auto-Negotiation The STP ports on the Switch have built-in "Auto-negotiation". This technology automatically sets the best possible bandwidth when a connection is established with another network device (usually at Power On or Reset). This is done by detecting the modes and speeds both connected devices are capable of. Both 10BASE-T and 100BASE-TX devices can connect with the port in either half- or full-duplex mode.

User’s Manual of GS-5220 PoE Series Managed Switch Solution: 1. AC power cord is not inserted or faulty. 2. Check that the AC power cord is inserted correctly. 3. Replace the power cord if the cord is inserted correctly; check that the AC power source is working by connecting a different device in place of the switch. 4. If that device works, refer to the next step. 5. If that device does not work, check the AC power.
