The left side panel contains heat vents. Figure 3-3. Side panel views of the Switch • The system fans are used to dissipate heat. The sides of the system also provide heat vents to serve the same purpose. Do not block these openings, and leave at least 6 inches of space at the rear and sides of the switch for proper ventilation.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 4 Connecting The Switch This chapter describes how to connect the DGS-3224TGR to your Gigabit Ethernet network. Switch to End Node End nodes include PCs outfitted with a 10, 100, or 1000 Mbps RJ-45 Ethernet/Fast Ethernet/Gigabit Ethernet Network Interface Card (NIC) and most routers. An end node can be connected to the switch via a Category 3, 4, 5, or 5e UTP/STP cable—for optimal performance, Category 5e is recommended.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Switch to Hub or Switch These connections can be accomplished in a number of ways using a normal cable. • A 10BASE-T hub or switch can be connected to the switch via a two-pair Category 3, 4, 5, or 5e UTP/STP cable. • A 100BASE-TX hub or switch can be connected to the switch via a two-pair Category 5 or 5e UTP/STP cable. • A 1000BASE-T switch can be connected to the switch via four-pair straight Category 5 or 5e UTP/STP cable. Figure 4-2.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 5 Switch Management and Operating Concepts This chapter discusses many of the concepts and features used to manage the switch, as well as the concepts necessary for the user to understand the functioning of the switch. Further, this chapter explains many important points regarding these features. Configuring the switch to implement these concepts and make use of its many features is discussed in detail in the next chapters.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide IP Addresses and SNMP Community Names Each switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The switch’s default IP address is 10.90.90.90. You can change the default switch IP Address to meet the specification of your networking address scheme. The switch is also assigned a unique MAC address by the factory.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide • New Root – This trap indicates that the switch has become the new root of the Spanning Tree, the trap is sent by the switch soon after its election as the new root. This implies that upon expiration of the Topology Change Timer the new root trap is sent out immediately after the switch’s election as the new root.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Authentication The authentication protocol ensures that both the router SNMP agent and the remote user SNMP application program discard packets from unauthorized users. Authentication is accomplished using ‘community strings’, which function like passwords. The remote user SNMP application and the router SNMP must use the same community string.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Spanning Tree 802.1w Rapid Spanning Tree The DGS-3224TGR implements two versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined by the IEE 802.1w specification and a version compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment implementing IEEE 802.1d, however the advantages of using RSTP will be lost. The IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1d STP standard.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 802.1d/802.1w Compatibility RSTP can interoperate with legacy equipment and is capable of automatically adjusting BPDU packets to 802.1d format when necessary. However, any segment using 802.1 STP will not benefit from the rapid transition and rapid topology change detection of RSTP. The protocol also provides for a variable used for migration in the event that legacy equipment on a segment is updated to use RSTP.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLANs allows VLANs to work with legacy switches that don’t recognize VLAN tags in packet headers. The tagging feature allows VLANs to span multiple 802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled on all ports and work normally. The IEEE 802.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide 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 EtherType field. When a packet’s EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Port VLAN ID Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact. This allows 802.1Q VLANs to span network devices (and indeed, the entire network – if all network devices are 802.1Q compliant). Unfortunately, not all network devices are 802.1Q compliant. These devices are referred to as tag-unaware. 802.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide If the packet is not tagged with VLAN information, the ingress port will tag the packet with its own PVID as a VID. The switch then determines if the destination port is a member of the same VLAN (has the same VID) as the ingress port. If it does not, the packet is dropped. If it has the same VID, the packet is forwarded and the destination port transmits it on its attached network segment.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Authentication Server The Authentication Server is a remote device that is connected to the same network as the Client and Authenticator, must be running a RADIUS Server program and must be configured properly on the Authenticator (Switch). Clients connected to a port on the Switch must be authenticated by the Authentication Server (RADIUS) before attaining any services offered by the Switch on the LAN.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Figure 5- 7. The Authenticator Client The Client is simply the endstation that wishes to gain access to the LAN or switch services. All endstations must be running software that is compliant with the 802.1x protocol. For users running Windows XP, that software is included within the operating system. All other users are required to attain 802.1x client software from an outside source.
DGS-3224TGR Gigabit Ethernet Switch User’s Guide Authentication Process Utilizing the three roles stated above, the 802.1x protocol provides a stable and secure way of authorizing and authenticating users attempting to access the network. Only EAPOL traffic is allowed to pass through the specified port before a successful authentication is made. This port is “locked” until the point when a Client with the correct username and password (and MAC address if 802.

DGS-3224TGR Gigabit Ethernet Switch User’s Guide When the DHCP client is in the renewing state, it must release its address immediately in the rare event that the DHCP server sends a negative acknowledgment. The DHCP server sends this message to inform a client that it has incorrect configuration information, forcing it to release its current address and acquire new information. If the DHCP client cannot successfully renew its lease, the client enters a rebinding state.
