  • Page 10: Basic Functions

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Basic Functions In general, the switch 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...

  • Page 11: Unicast Switching

    LB9030A-R2_LB9031A-R2_LB9032A-R2 UNICAST SWITCHING VLAN CLASSIFICATION When the switch receives a frame, it classifies the frame in one of two ways: - If the frame is untagged, the switch classifies the frame to an associated VLAN. - If the frame is tagged, the switch uses the tagged VLAN ID to identify the broadcasting domain of the frame.

  • Page 12: Multicast Switching

    LB9030A-R2_LB9031A-R2_LB9032A-R2 MULTICAST SWITCHING For multicast switching, the 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 following processes: VLAN CLASSIFICATION Same as for unicast switching.

  • Page 13: Vlan

    LB9030A-R2_LB9031A-R2_LB9032A-R2 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 14: Broadcast Containment

    LB9030A-R2_LB9031A-R2_LB9032A-R2 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 15: Vlan Membership

    LB9030A-R2_LB9031A-R2_LB9032A-R2 VLAN Membership VLAN IMPLEMENTATION ALLOWS: VLANs across multiple switches by using explicit or implicit tagging and the GARP/GVRP protocol defined in IEEE802.1p and 802.1Q. An end station’s network interface card may belong to multiple VLANs. A switch port may be associated with multiple VLANs. DEFINITIONS OF VLAN MEMBERSHIP VLAN implementation allows VLAN membership to be defined based on ports.

  • Page 16: Vlan Configuration

    LB9030A-R2_LB9031A-R2_LB9032A-R2 VLAN CONFIGURATION The switch provides a Local/Remote Management Console Interface for VLAN configuration and management An SNMP-based VLAN MIB is also provided. Intra-VLAN Communication The switch supports intra-VLAN communication through hardware, as described in “Basic Functions” section. Inter-VLAN Communication The switch supports inter-VLAN communication using CPU-based routing software.

  • Page 17: Gvrp

    LB9030A-R2_LB9031A-R2_LB9032A-R2 GVRP In addition to network management tools that allow network administrators to statically add and delete VLAN member ports, the routing switch supports GARP VLAN Registration Protocol (GVRP). GVRP supports dynamic registration of VLAN port members within a switch and across multiple switches.

  • Page 18: Igmp Snooping And Ip Multicast Filtering

    LB9030A-R2_LB9031A-R2_LB9032A-R2 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.
  • Page 19 LB9030A-R2_LB9031A-R2_LB9032A-R2 members and routers instead of flooding to all ports in the subnet (VLAN). Routing switches with multicast filtering/switching capability not only passively monitor IGMP Query and Report messages, DVMRP Probe messages, PIM, and MOSPF Hello messages; they also actively send IGMP Query messages to learn locations of multicast routers and member hosts in multicast groups within each VLAN.

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Switch Management ADMINISTRATION CONSOLE VIA RS-232 SERIAL PORT The 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 switch also hosts a point-and-click browser-based interface that lets users access full switch configuration and functionality from a Netscape or Internet Explorer browser.

  • Page 21: Installation

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Installation This chapter gives step-by-step instructions about how to install the switch: Selecting a Site for the Switch As with any electric device, you should place the 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 0 to 45 degrees Celsius.

  • Page 22: Connecting To Power

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Connecting to Power Internal 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 240 Vac. Step 2: Turn on the switch by flipping the ON/OFF switch on the rear of the unit to I (ON) position.

  • Page 23: Power-On Self Test (Post)

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Power-on Self test (POST) The Switch performs its Power-On Self Test (POST) when the power is switched on. During the POST, the switch CPU will: Perform a series of diagnostic procedures to make sure the basic system is functioning properly. A command line prompts when you press the Esc key on a terminal connected to the switch serial port during the POST process.

    LB9030A-R2_LB9031A-R2_LB9032A-R2 Web Management The 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 console port.

  • Page 30: Snmp-Based Network Management

    LB9030A-R2_LB9031A-R2_LB9032A-R2 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.
