    Gigabit Ethernet Switch User’s Guide BOUT UIDE This user’s guide tells you how to install your DGS-3208TG 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.

  • Page 13: Introduction

    Gigabit Ethernet Switch User’s Guide NTRODUCTION This section describes the features of the DGS-3208TG, 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.

    Gigabit Ethernet Switch User’s Guide segments. This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies.

    Gigabit Ethernet Switch User’s Guide Figure 2-1. Gigabit Ethernet Switch installed on a Desktop or Shelf Rack Installation The DGS-3208TG can be mounted in an EIA standard size, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the switch’s front panel (one on each side) and secure them with the screws provided.

  • Page 18: Power On

    Gigabit Ethernet Switch User’s Guide Power on The DGS-3208TG Switch can be used with AC power sources 100 - 240 VAC, 50 - 60 Hz. The Switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.

    Gigabit Ethernet Switch User’s Guide WITCH ANAGEMENT ONCEPTS Local Console Management Local console management involves the administration of the DGS-3208TG 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 25: Traps

    Gigabit Ethernet Switch User’s Guide 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 26: Mibs

    Gigabit Ethernet Switch User’s Guide MIBs The information stored in the Switch is known as the Management Information Base (MIB). The Switch uses the standard MIB-II Management Information Base module. Consequently, MIB values inside the Switch can be retrieved from any SNMP-based network manager. In addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base.

  • Page 27: Spanning Tree Algorithm

    Gigabit Ethernet Switch User’s Guide In the opposite case, if the Aging Time is too short, many entries may be aged out soon, resulting in a high percentage of received packets whose source addresses cannot be found in the address table. Spanning Tree Algorithm The Spanning Tree Algorithm (STA) in the Switch allows you to create alternative paths (with multiple switches or other types of bridges) in your network.

  • Page 28: On The Port Level

    Gigabit Ethernet Switch User’s Guide On the Port Level Root Port Each switch has a Root Port. This is the port that has the lowest Path Cost to the Root Bridge. In case there are several such ports, then the one with the lowest Port Identifier is the Root Port.
  • Page 29 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. STA setup can be somewhat complex.

  • Page 31: Vlans & Mac-Based Broadcast Domains

    Gigabit Ethernet Switch User’s Guide 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. Data transmitted to a specific host (destination address) will always be transmitted over the same port in a trunk group.

  • Page 32: Ieee 802.1Q Vlans

    Gigabit Ethernet Switch User’s Guide implemented on networks where stations are frequently moving, for example where people using notebook PCs are constantly plugging into different parts of the network. Setting up MAC-based broadcast domains is a relatively straightforward process. Simply create the broadcast domain by assigning it a name (description) and add MAC addresses for the stations that will be members.

  • Page 33: 802.1Q Vlans Spanning Multiple Switches

    Gigabit Ethernet Switch User’s Guide Figure 5-4. Example of typical VLAN configuration In the above example, there are three different 802.1Q VLANs and each port can transmit packets on one of them according to their Port VLAN ID (PVID). However, a port can receive packets on all VLANs (VID) that it belongs to.

  • Page 34: Vlans Over 802.1Q-Compliant Switches

    Gigabit Ethernet Switch User’s Guide Untagging The act of stripping 802.1Q VLAN information out of the packet header. Ports with untagging enabled will take all VLAN information out of all packets that flow out of a port. If the packet doesn’t have a VLAN tag, the port will not alter the packet, thus keeping the packet free of VLAN information.

  • Page 35: Port-Based Vlans

    Gigabit Ethernet Switch User’s Guide If the ingress port in step 4 were connected to a non-802.1Q-compliant device and was thus receiving untagged packets, it would tag its own PVID onto the packet and use this information to make forwarding decisions.

  • Page 36: Eliminating Broadcast Storms

    Gigabit Ethernet Switch User’s Guide domains are implemented at each switch port, they can be quite effective in limiting the scope of broadcast storms. Eliminating Broadcast Storms SNMP agents can be programmed to monitor the number of broadcast packets on switch ports and act on the data.

  • Page 37: Using The Console Interface

    Gigabit Ethernet Switch User’s Guide SING THE ONSOLE NTERFACE 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.

  • Page 38: Connecting To The Switch Using Telnet

    Gigabit Ethernet Switch User’s Guide Figure 6-1. Example of a console connection 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 39: Steps To Create Administrator Or Normal User Access

    Gigabit Ethernet Switch User’s Guide When you first connect to the Switch, you will be presented with the first login screen (shown below).

Configure Filtering and Forwarding Table screen The following fields at the top of the screen can be set: 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.

    Gigabit Ethernet Switch User’s Guide Advanced Figure 7-3. Configure Advanced Switch Features window The Switch features head of line (HOL) blocking prevention, a function designed to prevent forwarding of a packet to a “blocking” port, that is, a port where an excess of packets are queued up. Note that when a multicast packet or a packet with an unknown destination address needs to be forwarded to several ports, and if some of them are “blocking,”...
  • Page 88 Gigabit Ethernet Switch User’s Guide 1. Enable or disable the port. If you choose Disabled, devices connected to that port cannot use the Switch, and the Switch purges their addresses from its address table after the MAC address aging time elapses.
