1.2.4 Physical Ports

The Management Gigabit Switch provides 24x10/100Base-TX fixed ports and optional slots for 100Base-FX, 1000Base-SX/LX and 1000Base-T ports.

1.2.5 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 performs during unicast and multicast switching.

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.

1.Introduction-6

•If the frame is tagged, the switch uses the tagged VLAN ID to identify the broadcasting domain of the frame.

LEARNING

After VLAN classification, the switch checks the <source MAC address, VLAN> pair in the switching database (SDB) to see whether the <source MAC address, VLAN> pair is known.

•If it is unknown, the switch inserts the <source MAC address, VLAN> into the SDB and learns the <source MAC address, VLAN>.

•If it is known, the switch checks the <source MAC address, VLAN> for a mismatched port ID. If the port ID associated with the <source MAC address, VLAN> pair in the SDB is different than the receiving port, the switch modifies the port ID in the SDB and modifies its management database (MDB) accordingly.

1. Introduction-7

FILTERING

After learning the address, the switch checks:

•Whether the source port or destination port is in the forwarding state.

•Whether the source MAC address or destination MAC address is to be filtered.

•Whether the source port ID is the same as destination port ID.

If any of these conditions are met, the switch drops the receiving. Otherwise, it continues with the forwarding process described below.

FORWARDING

During the forwarding process, the switch checks whether the <destination MAC address, VLAN> pair is unknown.

•If it is unknown, the switch floods the receiving frame to all ports in the VLAN, excluding the source port.

•If it is known, the switch forwards the receiving frame to the port associated with the <destination MAC address, VLAN> pair. At the same time, the switch ascertains the individual’s port’s VLAN tagging/untagging configuration and corresponding VLAN ID to render the appropriate frame tagging when the frame is ready to be transmitted.

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.

1. Introduction-8

LEARNING

Same as for unicast switching.

FILTERING

After learning the address, the switch checks:

•Whether the source port or destination port is not in the forwarding state.

•Whether the source MAC address or destination MAC address is to be filtered.

•Whether the source port ID is the same as destination port ID.

If any of these conditions are met, the switch drops the receiving. Otherwise, it continues with the forwarding process described below.

FORWARDING

The 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.

AGING

The switch performs the aging process for the <MAC addresses, VLAN> pair in the switching database. Once a <MAC address, VLAN> pair is aged out, the SDB is modified.

SPANNING TREE

The switch supports one Spanning Tree per bridged network.

1. Introduction-9

1.2.6 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.

VLANs are configured through software rather than hardware, which makes them extremely flexible. One of the biggest advantages of VLANs is that when a computer is physically moved to another location, it can stay on the same VLAN without any hardware reconfiguration.

Because VLANs are not limited by the hardware constraints that physically connect traditional LAN segments to a network, they can define a network into various logical configurations. For example, VLANs can define a network by application. In this scenario, a company might create one VLAN for multimedia users and another for email users. VLANs can also define a network by department. For example, a company might have one VLAN for its Engineering Department, another for its Marketing Department, and another for its Account Payable Department.

VLANs can also be set up according to the organization structure within a company. For example, the company president might have his/her own VLAN, the executive staff might have a different VLAN, and the remaining employees might have yet a different VLAN.

As these examples show, VLANs offer unparalleled flexibility.

1. Introduction-10

The following sections describe how deploying VLANs can benefit organizations and reduce administration costs.

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. In addition, VLANs prevent broadcast storms from causing network meltdown due to volumes of traffic.

MULTICAST-BASED MULTIMEDIA APPLICATIONS

Multimedia applications, such as interactive training, video conferencing, and news-video transmissions, require large amounts of bandwidth. These applications are also extremely sensitive to variable delays, which are unavoidable on a shared Ethernet network. By defining a VLAN based on the IP multicast address for all subscribing members on the VLAN, sufficient bandwidth will be available for these application, providing true multimedia on Ethernet.

ENHANCED SECURITY

Because VLANs are self-contained, only the devices within the same VLAN can communicate with each other. If a device in one VLAN wants to communicate with a device in another VLAN, the traffic must go through a router.

1. Introduction-11

VLAN MEMBERSHIP

VLAN implementation allows:

•Up to 256 VLANs in one switch.

•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 belong to multiple VLANs.

•A switch port to be associated with multiple VLANs.

DEFINITIONS OF VLAN MEMBERSHIP

VLAN implementation allows VLAN membership to be defined based on ports. Port-based VLANs are organized by physical port number. For example, switch ports 1, 2, 4 and 6 can be grouped on VLAN, while server ports 3, 5, 7 and 8 can be on another VLAN. Broadcasts from servers within each group would only go to the members of its own VLAN. This ensures that broadcast storms cannot cause a network meltdown due to volumes of traffic.

VLAN MEMBERSHIP LEARNING

Port-based VLAN is defined using a static binding between a VLAN and its associated ports. The switch’s forwarding decision is based on the destination MAC address and its associated port ID. Therefore, to make valid forwarding and flooding decisions, the switch learns the relationship of the MAC address to its related port – and thus to the VLAN – at runtime.

REMOTE VLAN LEARNING

In addition to providing network management tools that allow network administrators to statically add and delete VLAN member ports, the switch also supports GVRP (GARP VLAN

1. Introduction-12

Registration Protocol). GVRP allows for dynamic registration of VLAN port members within switch and across multiple switches.

Other than supporting dynamic updating of registration entries in a switch, GVRP is used to communicate VLAN registration information to other VLAN-aware switches, so that a VLAN member can cover a wide span of switches on a network.

GVRP allows both VLAN-aware workstations and switches to issue and revoke VLAN memberships. VLAN-aware switches register an propagate VLAN membership to all ports that belong to the active topology of the VLAN.

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.

1. Introduction-13

1.2.7 Class-of-Service (CoS) Support

The 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.

Priority assignment to packet-based switches is accomplished through explicit assignment by end stations, which have applications that require a higher priority than best-effort data. This mechanism utilizes the IEEE802.1p and 802.1Q tag structure, which the switch uses to decide priority assignments for the received packets.

1.2.8 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.

In addition to dynamically updating registration entries within a switch, GVRP is used to communicate VLAN registration information to other VLAN-aware switches, so that members of a VLAN can cover a wide span of switches on a network.

GVRP allows both VLAN-aware workstations and switches to issue and revoke VLAN memberships. VLAN-aware switches register and propagate VLAN membership to all ports that are part of the active topology of the VLAN.

1. Introduction-14

1.2.9 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. If there is more than one router on the LAN performing IP multicasting, one of the routers is elected “querier” and assumes the responsibility of querying the LAN for group members.

Based on the group membership information learned from the IGMP, a router can determine which (if any) multicast traffic needs to be forwarded to each of its “leaf” subnetworks. Multicast routers use this information, along with a multicast routing protocol, to support IP multicasting across the Internet.

IGMP provides the final step in an IP multicast packet delivery service since it is only concerned with the forwarding of multicast traffic from the local route to group members on directly attached subnetworks.

Routing switches support IP Multicast Filtering by:

•Passively snooping on the IGMP Query and IGMP Report packets transferred between IP Multicast Routers and IP Multicast host groups to learn IP Multicast group members, and

•Actively sending IGMP Query messages to solicit IP Multicast group members.

1.Introduction-15

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; they also actively send IGMP Query messages to learn locations of multicast routers and member hosts in multicast groups within each VLAN.

Note, however, IGMP neither alters nor routes any IP multicast packets. Since IGMP is not concerned with the delivery of IP multicast packets across subnetworks, an external IP multicast router is needed if IP multicast packets have to be routed across different subnetworks.

1.2.10 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 boasts a point-and-click browser-based interface that lets users access full switch configuration and functionality from a Netscape or Internet Explorer browser.

1. Introduction-16

EXTERNAL SNMP-BASED NETWORK MANAGEMENT APPLICATION

The switch can also be configured via SNMP.

2. Installation -21

2.2.2 Cabling

Step 1: First, ensure the power of the switch and end devices is turned off.

<Note> Always ensure that the power is off before any installation.

Step 2: Prepare cable with corresponding connectors for each type of port in use.

<Note> To connect two regular RJ-45 ports between switches or hubs, you need a cross-over cable.

Step 3: Consult Cable Specifications Table on previous page for cabling requirements based on connectors and speed.

Step 4: Connect one end of the cable to the switch and the other end to a desired device.

Step 5: Once the connections between two end devices are made successfully, turn on the power and the switch is operational.

2. Installation -22

2.3 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 240 Vac.

Step 2: Disconnect the power cord if you want to shut down the switch.

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 integrity

•decompress the main switching software runtime image from the flash ROM into DRAM area

•begin executing the main switching software

A command line prompts when you press the Esc key on a terminal connected to the switch serial port during the POST process. Then you can execute the following options:

DOWNLOAD RUNTIME SOFTWARE FROM SERIAL PORT

This will download the runtime system image to the switch via the serial port. Before selecting this option, make sure:

•A host system is running a terminal emulation program that supports the Kermit file transfer protocol.

•The host system’s hard drive has the required binary file that will be downloaded to the switch.

2.Installation -23

CONFIGURE THE SYSTEM

This option lets you modify any configurable parameter in the switch’s flash ROM before the switch system boots.

RUN MANUFACTURING DIAGNOSTICS
