    This user’s guide tells you how to install your DGS-3208F stand-alone Switch, how to connect it to your Gigabit Ethernet network, and how to set its configuration using either the built-in console interface or Web- based management. Terms For simplicity, this documentation uses the terms “Switch” (first letter upper case) to refer to the DGS-3208F Gigabit Ethernet Switch, and “switch”...

  • Page 8: Introduction

    Gigabit Ethernet Switch User’s Guide NTRODUCTION This section describes the features of the DGS-3208F, as well as giving some background information about Gigabit Ethernet and switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet.

  • Page 9: Features

    Features The DGS-3208F Gigabit Ethernet Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously.

    The Console LED indicator will remain ON if there is a connection at the RS-232 port, otherwise this LED indicator is OFF. Power Failure As a precaution, the Switch should be unplugged in case of power failure. When power is resumed, plug the Switch back in.

    Comprehensive LED indicators display the condition of the Switch and status of the network. A description of these LED indicators follows (see LED Indicators). Rear Panel The rear panel of the Switch consists of an AC power connector. The following shows the rear panel of the Switch. XTERNAL Figure 3-2.

  • Page 15: Side Panels

    Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz. Side Panels The Switch’s side panels contain the system fans, two on the right and one on the left. The following shows the Switch’s right side panel.

  • Page 17: Connecting The Switch

    This chapter describes how to connect the DGS-3208F to your Gigabit Ethernet network. PC to Switch A PC can be connected to the Switch via a fiber optic cable. The PC should be connected to any of the eight ports (1x – 8x) of the DGS-3208F.

  • Page 19: Switch Management Concepts

    WITCH Local Console Management Local console management involves the administration of the DGS-3208F Switch via a direct connection to the RS-232 DCE console port. From the Main Menu screen of the console program, an Administrator or Normal User (defined in the next chapter) has privilege and access to manage, control, and monitor the many functions of the Switch.

  • Page 20: Traps

    In addition, you can also set in the Switch an IP Address for a gateway or a router. It is useful when the management station is not located on the same network as the Switch, making it necessary for the Switch to go through a gateway or router to reach the network manager.

  • Page 21: Mibs

    Example: if Port 1 receives a packet destined for Port 2, the Switch transmits that packet through Port 2 only, and transmits nothing through Port 1.

  • Page 22: Spanning Tree Algorithm

    Designated Bridge. Root Path Cost The Root Path Cost of a switch is the sum of the Path Cost of the Root Port and the Root Path Costs of all the switches that the packet goes through. The Root Path Cost of the Root Bridge is zero.

    BPDU packets sent by the Root Bridge to tell all other Switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
  • Page 24 Gigabit Ethernet Switch User’s Guide based on the STA calculation of the most current Bridge and Port settings. Now, if Bridge 1 broadcasts a packet to Bridge 3, then Bridge 3 will broadcast it to Bridge 2 and the broadcast will end there.

  • Page 25: Port Trunking

    The Switch supports up to four trunk groups, the first three which may include from two to four switch ports each. The fourth trunk group is two ports only. The switch treats all ports in a trunk group as a single port. As such, trunk ports will not be blocked by the spanning tree algorithm.

  • Page 26: Vlans & Mac-Based Broadcast Domains

    Two types of VLANs are implemented on the Switch: 802.1Q VLANs and port-based VLANs. MAC-based broadcast domains are a third option. Only one type of VLAN or broadcast domain can be active on the Switch at any given time, however. Thus, you will need to choose the type of VLAN or broadcast domain you wish to setup on your network and configure the Switch accordingly.

  • Page 27: Ieee 802.1Q Vlans

    (PVID=2). If the destination lies on another port (found through a normal forwarding table lookup), the Switch then looks to see if the other port (Port 4) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If port 4 is not a member of VLAN 2, then the packet will be dropped by the Switch and will not reach its destination.

    Filter is disabled, then the switch will process any packet received at this port in its normal fashion. Egress port A port on a switch where packets are flowing out of the switch, either to another switch or to an end station, and tagging decisions must be made.

    802.1Q VLAN information into each packet header, enabling other 802.1Q-compliant switches that receive the packet to know how to treat it. Upon receiving a tagged packet, an 802.1Q-compliant switch can use the information in the packet header to maintain the integrity of VLANs, carry out priority forwarding, etc.

  • Page 30: Broadcast Storms

    However, with the advent of VLANs, switches are now able to limit broadcast domains better and cheaper than routers. Also, many switches, including the DGS-3208F, have broadcast sensors and filters built into each port to further control broadcast storms.
  • Page 31 In the Switch, the default rising threshold is met when more than 500 broadcast packets per second are being detected on a specified port. Once the rising threshold is surpassed for a duration of more than 5 seconds, it will trigger the broadcast storm rising action configured by the user.

  • Page 32: Using The Console Interface

    SING THE Your Gigabit Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP Telnet protocol. You can use this facility to perform many basic network management functions. In addition, the console program will allow you to set up the Switch for management using an SNMP-based network management system.

  • Page 33: Connecting To The Switch Using Telnet

    Connecting to the Switch Using Telnet Once you have set an IP address for your Switch, you can use a Telnet program (in a VT-100 compatible terminal mode) to access and control the Switch. Most of the screens are identical, whether accessed from the console port or from a Telnet interface.

  • Page 47: Configure Filtering And Forwarding Table

    Configure Filtering and Forwarding Table When a packet hits the Switch, the Switch looks in the filtering and forwarding tables to decide what to do with the packet; either to filter it off the network, or to forward it through the port on which its destination lies.

  • Page 48: Configure Static Forwarding Table

    Lock Address Table (Stops Auto-Learning) This function is used mostly for security purposes. When the forwarding table is locked, the Switch will no longer learn the MAC addresses for new hosts. If your network configuration doesn’t change, locking the forwarding table helps keep intruders off your network, since any packet coming from an unknown source address will be dropped by the Switch.

  • Page 49: Configure Mac Address Filtering

    A total of ten destination addresses per page will be seen at the bottom of the screen. The Switch can hold up to 256 entries. Port The port number is entered in this field at the top of the screen. The Switch will always forward traffic to the specified device through this port.

    The Switch sends out SNMP traps to network management stations whenever certain exceptional events occur, such as when the Switch is turned on or when a system reset occurs. The Switch allows traps to be routed to up to four different network management hosts.

  • Page 68: Switch Monitoring

    The Switch uses an SNMP agent which monitors different aspects of network traffic. The SNMP agent keeps counters and statistics on the operation of the Switch itself, and on each port on the Switch. The statistics obtained can be used to monitor the conditions and general efficiency of the Switch.
