Chapter 1 Getting to Know Your Switch Figure 2 Bridging Application 1.1.3 High Performance Switching Example The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks. Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.
Page 21: Ways To Manage The Switch
Chapter 1 Getting to Know Your Switch 1.1.4.1 Tag-based VLAN Example Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.
Page 22 Chapter 1 Getting to Know Your Switch • Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch.

Page 27: Mini-Gbic Slots
Chapter 3 Hardware Panels Four 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a dual personality interface. The Switch uses up to one connection for each mini-GBIC and 1000Base-T Ethernet pair. The mini-GBIC slots have priority over the Gigabit ports. This means that if a mini-GBIC slot and the corresponding GbE port are connected at the same time, the GbE port will be disabled.
Page 28 Chapter 3 Hardware Panels Insert the transceiver into the slot with the exposed section of PCB board facing down. Press the transceiver firmly until it clicks into place. The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is functioning properly.

Page 113 Chapter 13 Spanning Tree Protocol The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence of the spanning tree than STP (while also being backwards compatible with STP-only aware bridges). In RSTP, topology change information is directly propagated throughout the network from the device that generates the topology change.
Page 114: Stp Port States
Chapter 13 Spanning Tree Protocol STP Port States STP assigns five port states to eliminate packet looping. A bridge port is not allowed to go directly from blocking state to forwarding state so as to eliminate transient loops.

HAPTER Differentiated Services 34.1 Differentiated Services Overview This chapter shows you how to configure Differentiated Services (DiffServ) on the Switch. Quality of Service (QoS) is used to prioritize source-to-destination traffic flows. All packets in the flow are given the same priority. You can use CoS (class of service) to give different priorities to different packet types.
Page 278: Activating Diffserv
Chapter 34 Differentiated Services The DSCP value determines the PHB (Per-Hop Behavior), that each packet gets as it is forwarded across the DiffServ network. Based on the marking rule different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.

HAPTER DHCP 35.1 DHCP Overview This chapter shows you how to configure the DHCP feature. DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual computers to obtain TCP/IP configuration at start-up from a server. If you configure the Switch as a DHCP relay agent, then the Switch forwards DHCP requests to DHCP server on your network.
Page 282: Dhcp Configuration
Chapter 35 DHCP DHCP Relay Configure DHCP relay on the Switch if the DHCP clients and the DHCP server are not in the same broadcast domain. During the initial IP address leasing, the Switch helps to relay network information (such as the IP address and subnet mask) between a DHCP client and a DHCP server. Once the DHCP client obtains an IP address and can connect to the network, network information renewal is done between the DHCP client and the DHCP server without the help of the Switch.

Appendix C IPv6 Global Address A global address uniquely identifies a device on the Internet. It is similar to a “public IP address” in IPv4. A global unicast address starts with a 2 or 3. Unspecified Address An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does not have its own address.
Page 364 Appendix C IPv6 Table 178 Reserved Multicast Address (continued) MULTICAST ADDRESS FF0A:0:0:0:0:0:0:0 FF0B:0:0:0:0:0:0:0 FF0C:0:0:0:0:0:0:0 FF0D:0:0:0:0:0:0:0 FF0E:0:0:0:0:0:0:0 FF0F:0:0:0:0:0:0:0 Subnet Masking Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F).
Page 365 Appendix C IPv6 combines its interface ID and global and subnet information advertised from the router. This is a routable global IP address. DHCPv6 The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration information to DHCP clients.
Page 366 Appendix C IPv6 such as the system name. The interface-ID option provides slot number, port information and the VLAN ID to the DHCPv6 server. The remote-ID option (if any) is stripped from the Relay-Reply messages before the relay agent sends the packets to the clients. The DHCP server copies the interface-ID option from the Relay-Forward message into the Relay-Reply message and sends it to the relay agent.
Page 367 Appendix C IPv6 determine whether the destination address is on-link and can be reached directly without passing through a router. If the address is onlink, the address is considered as the next hop. Otherwise, the Switch determines the next-hop from the default router list or routing table. Once the next hop IP address is known, the Switch looks into the neighbor cache to get the link-layer address and sends the packet when the neighbor is reachable.
Page 368 Appendix C IPv6 Double click Dibbler - a DHCPv6 client. Click Start and then OK. Now your computer can obtain an IPv6 address from a DHCPv6 server. Example - Enabling IPv6 on Windows 7 Windows 7 supports IPv6 by default. DHCPv6 is also enabled when you enable IPv6 on a Windows 7 computer.
Page 369 Appendix C IPv6 Click Close to exit the Local Area Connection Status screen. Select Start > All Programs > Accessories > Command Prompt. Use the ipconfig command to check your dynamic IPv6 address. This example shows a global address (2001:b021:2d::1000) obtained from a DHCP server.
