PAGE 53
User’s Manual of GS-5220 Series 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 54
User’s Manual of GS-5220 Series 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 55
User’s Manual of GS-5220 Series 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 56
User’s Manual of GS-5220 Series 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. This management method, in fact, uses two community strings: the get community string and the set community string.

User’s Manual of GS-5220 Series 4.5 Link Aggregation Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs). Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy. Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media types (UTP/Fiber, or different fiber types), provided they operate at the same speed.
PAGE 113
User’s Manual of GS-5220 Series The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems that require high speed redundant links.

User’s Manual of GS-5220 Series 4.6 VLAN 4.6.1 VLAN Overview A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. VLAN can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN. VLAN also logically segment the network into different broadcast domains so that packets are forwarded only between ports within the VLAN.
PAGE 121
User’s Manual of GS-5220 Series 4.6.2 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. An IEEE 802.
PAGE 122
User’s Manual of GS-5220 Series ■ 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 123
User’s Manual of GS-5220 Series 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.
PAGE 124
User’s Manual of GS-5220 Series ■ 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.

User’s Manual of GS-5220 Series 4.6.6 Port Isolation Overview When a VLAN is configured to be a private VLAN, communication between ports within that VLAN can be prevented. Two application examples are provided in this section: • Customers connected to an ISP can be members of the same VLAN, but they are not allowed to communicate with each other within that VLAN.
PAGE 134
User’s Manual of GS-5220 Series The configuration of promiscuous and isolated ports applies to all private VLANs. When traffic comes in on a promiscuous port in a private VLAN, the VLAN mask from the VLAN table is applied. When traffic comes in on an isolated port, the private VLAN mask is applied in addition to the VLAN mask from the VLAN table. This reduces the ports to which forwarding can be done to just the promiscuous ports within the private VLAN.

User’s Manual of GS-5220 Series 4.7 Spanning Tree Protocol 4.7.1 Theory The Spanning Tree protocol can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. 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.

User’s Manual of GS-5220 Series  The path cost to the root from the transmitting port  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 Series  From forwarding to disabled  From disabled to blocking Figure 4-7-1: STP Port State Transitions You can modify each port state by using management software. When you enable STP, every port on every switch in the network goes through the blocking state and then transitions through the states of listening and learning at power up. If properly configured, each port stabilizes to the forwarding or blocking state.

User’s Manual of GS-5220 Series 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 Series 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. 1000BASE-T can be only connected in full-duplex mode.

User’s Manual of GS-5220 Series The DHCP server ensures that all IP addresses are unique, for example, no IP address is assigned to a second client while the first client's assignment is valid (its lease has not expired). Therefore, IP address pool management is done by the server and not by a human network administrator. Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task.
