  • Page 14: Basic Functions

    Basic Functions In general, the LBG1000Aswitch is responsible for switching both VLAN tagged and untagged frames from a receiving port to one or more transmitting ports. The switch performs multiple steps during the switching process: VLAN CLASSIFICATION LEARNING FILTERING FORWARDING AGING Below is additional information about tasks that the switch performs during unicast and multicast switching.

  • Page 15: Unicast Switching

    Multicast Switching For multicast switching, the LBG1000A switch checks whether the received frame is a BPDU. If a BPDU is received, the switch forwards the frame to the CPU for processing by the spanning tree protocol. Otherwise, the switch performs the...
  • Page 16 Manageable Gigabit Switch FORWARDING The LBG1000A switch floods the received multicast frame to all ports that are in forwarding state within the VLAN, excluding the source port. At the same time, the switch ascertains the individual port’s VLAN tagging/untagging configuration and corresponding VLAN ID to render the appropriate frame tagging when the frame is ready to be transmitted.

  • Page 17: Vlan

    VLAN A virtual LAN (VLAN) is a network of computers that behave as if they are connected to the same wire, even though they may actually be physically located on different segments of a LAN. VLANs are analogous to a group of end stations, perhaps on multiple physical LAN segments that are not constrained by their physical location and can communicate as if they were on a common LAN.

  • Page 18: Broadcast Containment

    Broadcast Containment In traditional networks, traffic broadcasts to all network devices, whether they are the intended recipients or not. However, VLANs can be set up to contain only those devices that need to communicate with each other. As a result, VLANs significantly reduce network congestion.

  • Page 19: Vlan Membership

    VLAN membership to all ports that belong to the active topology of the VLAN. VLAN CONFIGURATION The LBG1000A switch provides a Local/Remote Management Console Interface for VLAN configuration and management An SNMP-based VLAN MIB is also provided.

  • Page 20: Class-Of-Service (Cos) Support

    Class-of-Service (CoS) Support The LBG1000A switch provides four transmit queues on each port, with a weighted round-robin scheme. These functions can be used to provide independent priorities for various types of data including real-time video, real-time voice, and best-effort data.

  • Page 21: Igmp Snooping And Ip Multicast Filtering

    IGMP Snooping and IP Multicast Filtering The Internet Group Management Protocol (IGMP) runs between hosts and their immediately neighboring multicast routers. The protocol’s mechanisms allow a host to inform its local router that it wants to receive transmissions addressed to a specific multicast group. Routers periodically query the LAN to determine if known group members are still active.
  • Page 22 The purpose of IP multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts members and routers instead of flooding to all ports in the subnet (VLAN). Routing switches with IP multicast filtering/switching capability not only passively monitor IGMP Query and Report messages, DVMRP Probe messages, PIM, and MOSPF Hello messages;...

  • Page 23: Switch Management

    Switch Management Administration console via RS-232 serial port The LBG1000A switch provides an onboard serial port, which allows the switch to be configured via a directly connected terminal or a Telnet session. Web-based browser interface The LBG1000A switch also boasts a point-and-click browser-based interface that lets users access full switch configuration and functionality from a Netscape or Internet Explorer browser.

  • Page 24: Installation

    This chapter gives step-by-step instructions about how to install the LBG1000A switch: Selecting a Site for the Switch As with any electric device, you should place the LBG1000A switch where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements: The ambient temperature should be between 32 and 104 degrees Fahrenheit (0 to 40 degrees Celsius).

  • Page 25: Connecting To Power

    Connecting to Power Step 1: Connect the supplied AC power cord to the receptacle on the back of the switch, and then plug it into a standard AC outlet with a voltage range from 100 to 260 Vac.

  • Page 29: Switch Management

    Manageable Gigabit Switch Switch Management This chapter explains the methods that you can use to configure management access to the switch. It describes the types of management applications and the communication and management protocols that deliver data between your management device (workstation or personal computer) and the system. It also contains information about port connection options.

  • Page 30: Management Access Overview

    Management Access Overview The LBG1000A switch gives you the flexibility to access and manage the switch using any or all of the following methods. The administration console and web browser interface support are embedded in the switch software and are available for immediate use.

  • Page 31: Administration Console

    Administration Console The administration console is an internal, character-oriented, menu-driven user interface for performing system administration such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal, personal computer, Apple Macintosh, or workstation connected to the switch’s console port.

  • Page 32: Modem Access

    Modem Access You can access the switch’s administration console from a PC or Macintosh using an external modem attached to the console port. The switch management program provides Console Port screen, accessible from the Basic Management screen, that lets you configure parameters for modem access. When you have configured the external modem from the administration console, the switch transmits characters that you have entered as output on the modem port.

  • Page 33: Web Management

    Web Management The LBG1000A switch provides a browser interface that lets you configure and manage the switch remotely. After you set up your IP address for the switch, you can access the switch’s web interface applications directly in your web browser by entering the IP address of the switch. You can then use your web browser to list and manage switch configuration parameters from one central location, just as if you were directly connected to the switch’s...

  • Page 34: Snmp-Based Network Management

    SNMP-Based Network Management You can use an external SNMP-based application to configure and manage the switch. This management method requires the SNMP agent on the switch and the SNMP Network Management Station to use the same community string. This management method, in fact, uses two community strings: the get community string and the set community string.

  • Page 35: Protocols

    Protocols The LBG1000A switch supports the following protocols: VIRTUAL TERMINAL PROTOCOLS, SUCH AS TELNET A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a management session from a Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on the switch before you can establish access to it with a virtual terminal protocol.

  • Page 36: Menu-Driven Console Management

    Menu-Driven Console Management The LBG1000A switch provides a menu-driven console interface for configuration purposes. The switch can be configured either locally through its RS-232 port or remotely via a Telnet session. For the later, you must specify an IP address for the switch first.
