  • Page 7: About This Guide

    BOUT UIDE This user’s guide will show you how to install your DES-2108, and how to connect it to your network. Terms For simplicity, this documentation uses the terms “Switch” (first letter upper case) to refer to the DES-2108, and “switch” (first letter lower case) to refer to all Ethernet switches, including the DES-2108.

  • Page 8: Introduction

    NTRODUCTION This section describes the features of the DES-2108, as well as giving some background information about Fast Ethernet and Switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks.

  • Page 9: Switch Description

    Switch Description The DES-2108 is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100 Mbps bandwidth. The Switch has 8 UTP ports and Auto MDI-X/MDI-II convertible ports that can be used for up-linking to another switch.

  • Page 10: Features

    Management engine can be configure the Switch's settings for priority queuing, VLANs, and port monitoring, and port speed. Features The DES-2108 was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously.

  • Page 11: Ports

    Supports a packet buffer of up to 256 Kbytes. IGMP Snooping support. SNMP support. Port Mirror support. MIB support for: RFC1213 MIB II. Private MIB. Ports Eight (8) 10/100Mbps 100BASE-TX (Auto MDI-X/MDI-II) ports for connecting to end stations, servers, hubs and other networking devices. All UTP ports can auto-negotiate between 10Mbps and 100Mbps, half-duplex and full duplex, and flow control.

  • Page 12: Unpacking And Setup

    This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: One DES-2108 Fast Ethernet Switch Four rubber feet with adhesive backing One AC power adapter Mounting kit CD-ROM (Including this User’s Guide and Utility)

  • Page 13: Mounting The Switch On A Wall

    Mounting the Switch on a Wall The DES-2108 can also be mounted on a wall. Two mounting slots are provided on the bottom of the switch for this purpose. Please make sure that the front panel is exposed in order to view the LEDs. Please refer to the illustration below.

  • Page 14: Power On

    Power on The DES-2108 can be used with AC power sources 100 - 240 VAC, 50 - 60 Hz. The Switch’s power adapter will adjust to the local power source automatically. Plug one end of the DC output into the power jack of the Switch and the other end into the local power source outlet.

  • Page 15: Rear Panel

    DC Power Jack: Power is supplied through an external DC power adapter. Check the technical specification section for information about the DC power input voltage. DES-2108 does not include a power button, plugging its power adapter into a power outlet will immediately power it on. LED Indicators The LED indicators of the Switch include Power, CPU and Port Status LEDs.

  • Page 39: Configuration > Igmp Snooping

    Configuration > IGMP Snooping With Internet Group Management Protocol (IGMP) snooping, the Web-Smart Switch can make intelligent multicast forwarding decisions by examining the contents of each frame’s Layer 3 IP header. IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the Web-Smart Switch will forward IP multicast traffic only to connections that have group members attached.
  • Page 40 Max Response Time (10-25 sec): The Max Response Time specifies the maximum allowed time before sending a responding report. Adjusting this setting effects the "leave latency", or the time between the moment the last host leaves a group and when the routing protocol is notified that there are no more members.
  • Page 41 'RouterPortPurgeInterval' time, the learnt router port entry will be purged. Default is 125 seconds. Leave Time (0-25 sec): This is the interval after which a Leave message is forwarded on a port. When a leave message from a host for a group is received, a group-specific query is sent to the port on which the leave message is received.
