DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Safety Instructions Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. Throughout this document, the caution icon ( ) is used to indicate cautions and precautions that you need to review and follow.
Page 13: General Precautions For Rack-Mountable Products
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch • To help prevent electric shock, plug the system and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.
Page 14: Protecting Against Electrostatic Discharge
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
Page 15: Introduction
DES-3800 Series The DES-3800 switch series is a member of the D-Link xStack switch family. xStack is a complete family of stackable devices that ranges from edge 10/100Mbps switches to core Gigabit switches. xStack provides unsurpassed performance, fault tolerance, scalable flexibility, robust security, standard-based interoperability and an impressive support for 10 Gigabit technology to future- proof departmental and enterprise network deployments with an easy migration path.
Page 16: Gigabit Ethernet Technology
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch has two combo 1000 Base-T/SFP ports on the front panel and two 1000 Base-T ports on the back. These gigabit combo ports are ideal for connecting to a server or network backbone. See the “Ports” section below for differences between the front and rear Gigabit combo ports.
Page 17: Ports
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Full- and half-duplex for both 10Mbps and 100Mbps connections. Full duplex allows the switch port to simultaneously • transmit and receive data. It only works with connections to full-duplex-capable end stations and switches. Connections...
Page 18: Front-Panel Components
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch NOTE: The SFP combo ports on the Switch cannot be used simultaneously with the corresponding 1000BASE-T ports. If both ports are in use at the same time (ex. port 27 of the SFP and port 27 of the 1000BASE-T), the SFP ports will take priority over the combo ports and render the 1000BASE-T ports inoperable.
Page 19: Led Description
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch DES-3828/DES-3828DC LEDs The front panel of DES-3828/DES-3828DC has LED indicators for power, console, RPS (DES-3828 only), 27GE (rear port), 28 GE (rear port), for each of the twenty-four 10/100 Mbps Ethernet ports, and for the two 1000BASE-T/SFP ports.

Page 38: Password Protection
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Password Protection The Switch does not have a default user name and password. One of the first tasks when settings up the Switch is to create user accounts. If logging in using a predefined administrator-level user name, users will have privileged access to the Switch's management software.
Page 39: Snmp Settings
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch SNMP Settings Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices.
Page 40: Ip Address Assignment
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch IP Address Assignment 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.
Page 41 DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Figure 4- 4. Assigning the Switch an IP Address In the above example, the Switch was assigned an IP address of 10.53.13.83 with a subnet mask of 255.0.0.0. The user may also use the CIDR form to set the address (10.53.13.83/8).

DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Notes About VLANs on the DES-3800 Series No matter what basis is used to uniquely identify end nodes and assign these nodes VLAN membership, packets cannot cross VLANs without a network device performing a routing function between the VLANs.
Page 90: Q Vlan Tags
DES-3800 Series Layer 3 Stackable Fast Ethernet 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 EtherType field. When a packet's EtherType field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Page 91: Port Vlan Id
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch 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).
Page 92: Default Vlans
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Default VLANs The Switch initially configures one VLAN, VID = 1, called "default." The factory default setting assigns all ports on the Switch to the "default." As new VLANs are configured in Port-based mode, their respective member ports are removed from the "default."...
Page 93: Double Vlans
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Double VLANs Double or Q-in-Q VLANs allow network providers to expand their VLAN configurations to place customer VLANs within a larger inclusive VLAN, which adds a new layer to the VLAN configuration. This basically lets large ISP's create L2 Virtual Private Networks and also create transparent LANs for their customers, which will connect two or more customer LAN points without over-complicating configurations on the client's side.
Page 94: Regulations For Double Vlans
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Regulations for Double VLANs Some rules and regulations apply with the implementation of the Double VLAN procedure. 1. All ports must be configured for the SPVID and its corresponding TPID on the Service Provider’s edge switch.

DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Port Access Entity (802.1X) 802.1x Port-Based and MAC-Based Access Control The IEEE 802.1x standard is a security measure for authorizing and authenticating users to gain access to various wired or wireless devices on a specified Local Area Network by using a Client and Server based access control model.
Page 221 DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch 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.

Port-Based Access Control – This method requires only one user to be authenticated per port by a remote RADIUS server to allow the remaining users on the same port access to the network.
Page 223: Understanding 802.1X Port-Based And Mac-Based Network Access Control
DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch Understanding 802.1x Port-based and MAC-based Network Access Control The original intent behind the development of 802.1X was to leverage the characteristics of point-to-point in LANs. As any single LAN segment in such infrastructures has no more than two devices attached to it, one of which is a Bridge Port. The Bridge Port detects events that indicate the attachment of an active device at the remote end of the link, or an active device becoming inactive.
