CHAPTER 1 INTRODUCTION

WGSW-404 and WGSW-2402A are ultra-fast high-performance switches with non-blocking switch

fabric of 16Gbps and 12.8Gbps. WGSW-404 is a backbone switch with 4-port 10/100/1000Mbps

RJ-45 and 4-slot for media expansion. WGSW-2402A is designed to be a workgroup switch with

24-port 10/100Mbps RJ-45 and 2-slot for media expansion. Their expansion slots support

1000Base-T, 1000Base-SX and 100Base-FX modules that provide great flexibility on enterprise and

FTTB application. In the following section, the short term “WGSW” will be used to represent both

WGSW-2402A and WGSW-404

The WGSW switch can be stacked up to 8 units together through Ethernet interface and managed by

single IP. You can stack 8 WGSW-2402A to get up to 192 100Base-TX ports plus 2 Gigabit port or 8

WGSW-404 to get 50 Gigabit ports in single stack. Mix them in a single stack is also possible to get

maximum flexibility. Most stacked switches are limited by the length of a proprietary stack cable,

WGSW switch, however, the maximum distance between two stacked switches can be up to 2

kilometers using Ethernet stack connectivity.

Designed as the Layer 2 switch but with layer 3 software routing function, the WGSW can easily fit in

your network configuration and can be executed for its management functions through the console

telnet and the web. SNMP MIBII, Bridge MIB, RMON groups 1,2,3,9 and enterprise private MIB are

also supported to get the maximum management functionality.

The standard IEEE 802.1Q with VLAN tagging feature makes logically separating nodes easier, with up

to 128 VLAN groups allowed on the WGSW switch. IGMP snooping is provided to prevent flooding of IP

multicast traffic. Port security and MAC addresses filtering are also included as a standard feature to

enhance overall network access security.

8 priority queues on Gigabit port and 4 on 10/100port are provided with versatile scheduling methods

including delay bound, strict priority, WFQ and best effort. This ensures critical applications get the

bandwidth and priority they need. Rate control is also supported to allow bandwidth allocation based

on ports.

Throughout this user’s manual, the Intelligent Gigabit Ethernet Switch, WGSW-404 and WGSW-2402A

will be referred to as the Managed Switch or the Switch or WGSW.

2.4 Installing the Switch

The Switch is designed for office use, where it can be free standing, desktop-mounted, or mounted in

most standard 19-inch equipment racks. If you prefer, you can rack-mount the Switch in a wiring closet

or equipment room using two mounting brackets and six screws.

When choosing a location for the Switch, observe the following guidelines:

 Make sure the Switch is accessible and that the cables can be connected easily.

 Keep cabling away from sources of electrical noise such as radios, transmitters, and broadband

amplifiers as well as power lines and fluorescent lighting fixtures.

 Prevent water or moisture from entering the Switch case.

 Make sure there are no obstructions to restrict airflow around the Switch. We recommend that you

provide a minimum of 25 millimeter (1-inch) clearance.

 Do not place liquids or other objects on top of the Switch.

 If the Switches are freestanding, do not stack more than four switches on top of one another.

- 12 -

2.4.1 Pre-Installation Considerations

Fast Ethernet Topology Considerations

If you will be using the Switch for Fast Ethernet (100 Mbps) operation, observe the following guidelines:

 The maximum unshielded twisted-pair (UTP) cable length is 100 meters (328 feet) over Category 5

cable.

 Single-repeater topologies permit a total network span of 325 meters (1066 feet).

Full-Duplex Considerations

The Switch provides full-duplex support for its Fast Ethernet ports. Full-duplex operation allows frames

to be sent and received simultaneously, doubling a link’s potential data throughput. If you will be using

the Switch in full-duplex mode, the maximum UTP cable length is 100 meters (328 feet) over Category

5 cable.

2.4.2 Desktop or Shelf Mounting

To install the Switch on a desktop or shelf, simply complete the following steps:

Step 1 Place the Switch on a desktop or shelf near an AC power source. Step 2 Keep enough ventilation space between the Switch and the surrounding objects.

Note: When choosing a location, keep in mind the environmental restrictions. Please also

refer to Chapter 1, section 1.3 product specification for the details.

Step 3 Connect the Switch to network devices.

A. Connect one end of a standard network cable to the 10/100 RJ-45 ports on the front of

the Switch.

B. Connect the other end of the cable to the network devices such as printer servers,

workstations or routers.

Note: It is strongly recommended to use the UTP Category 5 network cabling with RJ-45 tips

for the network connection. For more information, please see the Cable Specifications in Appendix A, Cable Specifications.

Step 4 Supply power to the Switch.

A. Connect one end of the power cable to the Switch. B. Connect the power cube end of the power cable to a standard wall outlet.

When the Switch receives power, the Power LED should remain solid Green.

2.4.3 Rack-Mounting

The following procedure describes how to install the Switch in a standard 19-inch rack.

 Disconnect all cables from the Switch.

 Remove all adhesive pads from the bottom of the Switch.

Step 1 Place the Switch right side up on a hard flat surface, with the front panel facing you. Step 2 Locate a mounting bracket over the mounting holes on one side of the Switch

IGURE

Step 3 Insert three screws and use a screwdriver to secure. Step 4 Repeat the two previous steps for the other side of the Switch. Step 5 Insert the Switch into the 19-inch rack and secure with suitable screws. Make sure the

CHAPTER 3 CONFIGURATION

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.

This chapter covers the following topics:

 Management Access Overview

 Key Concepts

 Key Guidelines for Implementation

 Administration Console Access

 Web Management Access

 SNMP Access

 Standards, Protocols, and Related Reading

3.1 Management Access Overview

The Switch gives you the flexibility to access and manage the Switch using any or all of the following

methods:

 An administration console

 Web browser interface

 An external SNMP-based network management application

The administration console and Web browser interface support are embedded in the Switch software

and are available for immediate use. Each of these management methods has their own advantages.

Table 3-1 compares the three management methods.

 Requires SNMP manager

software

 Least visually appealing of all

three methods

 Some settings require calculations  Security can be compromised

(hackers need only know the community name)

3.1.1 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 (serial) port.

There are two ways to use this management method: via direct access or modem port access. The

following sections describe these methods. For more information about using the console, refer to

Chapter 4 Menu-Driven Console Management.

3.1.2 Direct Access

Direct access to the administration console is achieved by directly connecting a terminal or a PC

equipped with a terminal-emulation program (such as HyperTerminal) to the Switch console (serial)

port.

When using this management method, a null-modem cable is required to connect the Switch to the PC.

After making this connection, configure the terminal-emulation program to use the following

parameters:

The default parameters are:

 115,200 bps

 8 data bits

 No parity

 1 stop bit

You can change these settings, if desired, after you log on. This management method is often preferred

because you can remain connected and monitor the system during system reboots. Also, certain error

messages are sent to the serial port, regardless of the interface through which the associated action

was initiated. A Macintosh or PC attachment can use any terminal-emulation program for connecting to

the terminal serial port. A workstation attachment under UNIX can use an emulator such as TIP.

- 16 -

3.1.3 Modem Port Access

You can access the Switch’s administration console from a PC or Macintosh using an external modem

attached to the console (serial) port. The Switch management program provides a Console Port

screen, accessible from the Basic Management screen, that lets you configure parameters for modem

access (see Chapter 4 Menu-Driven Console Management). After configuring 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. The Switch echoes characters that it receives as input

on the modem port to the current ad-ministration console session. The console appears to be directly

connected to the external modem.

3.2 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. For more information, see Chapter 5, Browser Management.

Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape Navigator 4.03

or later.

 Netscape Navigator — if you use Netscape Navigator 4.03 or 4.04, install the Netscape JDK 1.1

Patch. Download the patch from the following location:

http://www.netscape.com/

If you encounter problems accessing Help files when you use Netscape, clear the browser memory

cache and disk cache, and restart the browser.

 Internet Explorer — if you use Internet Explorer 4.01, install the latest 4.01 Service Pack 1. This

service pack makes Internet Explorer Year 2000 compliant and fixes other product-support issues.

Download the 4.01 Service Pack 1 from the following location:

http://www.microsoft.com/msdownload/iebuild/ie4sp1_win32/en/ie4sp1_win32.htm

If the above link is unavailable, download the service pack from the Microsoft home page:

http://www.microsoft.com

- 17 -

3.3 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. If the SNMP network management

station only knows the set community string, it can read and write to the MIBs. However, if it only knows

the get community string, it can only read MIBs. The default gets and sets community strings for the

Switch are public.

3.4 Protocols

The Switch supports the following protocols:

 Virtual terminal protocols, such as Telnet

 Simple Network Management Protocol (SNMP)

3.4.1 Virtual Terminal Protocols

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.

Note: Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal

directly to the console (serial) port.

3.4.2 SNMP Protocol

Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor

IP networks. SNMP supports transaction-based queries that allow the protocol to format messages and

to transmit information between reporting devices and data-collection programs. SNMP runs on top of

the User Datagram Protocol (UDP), offering a connectionless-mode service.

- 18 -

3.4.3 Management Architecture

All of the management application modules use the same Messaging Application Programming

Interface (MAPI). By unifying management methods with a single MAPI, configuration parameters set

using one method (console port, for example) are immediately displayable by the other management

methods (for example, SNMP agent of Web browser).

The management architecture of the Switch adheres to the IEEE open standard. This compliance

assures customers that the Switch is compatible with, and will interoperate with other solutions that

adhere to the same open standard.

- 19 -

Chapter 4 Menu-Driven Console Management

The 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. This chapter

describes how to configure the Switch using its menu-driven console. The figures in this chapter will

base on WGSW-2402A, for WGSW-404, however, the setup steps are the same.

4.1 Logging on to the Switch

Enter the console interface factory default console name “admin” without password (or enter a

user-defined pass-word if you changed the factory default password). The Switch Management screen

in Figure 4-1 appears, with the Basic option highlighted.

Note:

Only one console and three telnet-users can log on to the Switch concurrently. However, it is

not recommended that multiple users modify the configuration at the same time.

IGURE

5-2 L2 S

WITCHING DATABASE SCREEN

The Switch can be viewed from the four perspectives in the L2 Switching DataBase screen in Figure

5-2:

 VLAN & PVID Perspective see section 5.2 “VLAN & PVID Perspective”.  IP Multicast Group Perspective — see section 5.3 “IP Multicast Group Perspective”.  MAC Address Perspective see section 5.4 “MAC Address Perspective”.  Port Perspective see section 5.5 “Port Perspective”.

These four views allow a network administrator to manage and monitor VLANs and their associated

MAC addresses and ports effectively from different views.

5.2 VLAN & PVID Perspective

Packets received by the Switch will be treated in the following way with regard to the Switch's VLAN

settings:

1. When an untagged packet enters a port, it will be automatically tagged with the port's VLAN ID tag

number. Each port has a default VLAN ID setting which is user configurable (the default setting is

1). The default VLAN ID setting for each port can be changed in the PVID settings of console or

web.

2. When a tagged packet enters a port, the tag for that packet will be unaffected by the PVID Setting.

3. The packet will now proceed to the VLAN specified by it's VLAN ID tag number.

- 50 -

4. If the port in which the packet entered does not have membership with the VLAN specified by the

packets VLAN ID tag, the packet will be dropped. Port VLAN membership settings are changed in

the VLAN settings page.

5. If the port has membership to the VLAN specified by the packet's VLAN ID, the packet will be able

to be sent to other ports with the same VLAN ID membership.

6. Packets leaving the Switch will be either tagged or untagged depending on the setting specified

for that port’s membership properties.

The following sections describe the default VLAN, how to obtain a VLAN perspective and how to set the

PVID. For more information regarding to VLAN, please refer to appendix for more detail.

5.2.1 Default VLAN

The IEEE 802.1q standard defines VLAN ID #1 as the default VLAN. The default VLAN includes all the

ports as the factory default. The default VLAN’s egress rule restricts the ports to be all untagged, so it

can, by default, be easily used as a simple 802.1d bridging domain. The default VLAN’s domain shrinks

as untagged ports are defined in other VLANs.

5.2.2 Obtaining a VLAN Perspective

The following procedure describes how to obtain a VLAN perspective. For convenience, the VLAN ID

appears as both decimal and hexadecimal values side by side in the VLAN perspective screen.

5.3 IP Multicast Group Perspective

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

for-warded to each of its “leaf” subnetworks. Multicast routers use this information, along with a

multicast routing protocol, to support IP multicasting across the Internet.

- 69 -

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 router to group members on directly attached

subnetworks. The Switch 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.

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).

The Switch 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 multi-cast 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 subnets, an external IP multicast router is needed if IP

multicast packets have to be routed across different subnets.

The IP multicast group perspective provides information associated with an IP multicast group. To

obtain an IP multicast group perspective:

1. From the L2 Switching DataBase screen, highlight IP Multicast Group Perspective and press the

Enter key. A screen similar to the following appears.

5.6.1 IP and RIP Settings

If you select IP & RIP Settings from the IP Networking screen, a screen similar to the following

appears, with a list of the VLAN IDs, IP addresses, subnet masks, proxy ARPs, and RIPs currently

defined.

The Switch supports both static and dynamic routing.

 Static routing requires routing information to be stored in the Switch, either manually or when a

connection is set up by an application outside the Switch.

 Dynamic routing uses a routing protocol to exchange routing information, calculate routing tables,

and respond to changes in the status or loading of the network.

Dynamic routing involves the determination and updating of all the routing information required for

packet forwarding.

 Handling routing protocols

 Updating the routing table

The Switch supports RIP and RIP-2 dynamic routing protocols.

- 83 -

The RIP protocol is the most widely used routing protocol. The RIP protocol uses a distance

vector-based approach to routing. Routes are determined on the basis of minimizing the distance

vector, or hop count, which serves as a rough estimate of transmission cost. Each router broadcasts its

advertisement every 30 seconds, together with any updates to its routing table. This allows all routers

on the network to learn consistent tables of next hop links which lead to relevant subnets. Just as Layer

2 switches use the Spanning Tree Algorithm to prevent loops, routers also use methods for preventing

loops that would cause endless retransmission of data traffic. RIP utilizes the following three methods

to prevent loops from occurring:

 Split horizon— never propagate routes back to an interface port from which they have been

acquired.

 Poison reverse— propagate routes back to an interface port from which they have been acquired,

but set the distance vector metrics to infinity. (This provides faster convergence.)

 Triggered updates— whenever a route gets changed, broadcast an update message after waiting

for a short random delay, but without waiting for the periodic cycle.

RIP-2 is a compatible upgrade to RIP. RIP-2 adds useful capabilities for plain text authentication,

multiple independent RIP domains, variable length subnet masks, and multicast transmissions for route

advertising (RFC 1388).

There are several serious problems with RIP that you should consider before deciding which routing

protocol to use for your network. First of all, RIP (version 1) has no knowledge of subnets, both RIP

versions can take a long time to converge on a new route after the failure of a link or router during

which time routing loops may occur, and its small hop count limitation of 15 restricts its use to smaller

networks. Moreover, RIP (version 1) wastes valuable network bandwidth by propagating routing

information via broadcasts, nor does it consider enough network variables to make the best routing

decision.

Note: Before you can define a VLAN’s IP settings, you must first create a VLAN as described under

“Creating a New VLAN”.

- 84 -

To modify the settings shown:

IGURE

5-45

1. Use the Down Arrow key to highlight the row that contains the parameters you want to change, and

then press Enter. A screen similar to the following appears, with the highlight in the IP Address

field.

The available options are:

 IP Address: The IP address of the Switch for this VLAN.  IP Subnet Mask: The subnet mask of the IP.  Frame Type: Either Ethernet II or Ethernet SNAP. Default is Ethernet II.  BOOTP: Specify how the IP address of the Switch for this VLAN is assigned. Default is

None for manually configuring. You can also specify BOOTP or DHCP to get IP address.

Please note that you should setup a BOOTP server or DHCP server on this VLAN network.

 Proxy ARP: When a node in the attached subnetwork does not have routing or a default

gateway configured, ARP Proxy can be used to forward an ARP request to a remote

subnetwork. When the Switch receives an ARP request for a remote network and ARP Proxy

is enabled, it determines if it has the best route to the remote network, and then answers the

ARP request by sending its own MAC address to the requesting node. That node then sends

traffic to the Switch, which in turn uses its own routing table to forward the traffic to the remote

destination. End stations that require Proxy ARP must view the entire network as a single

network. These nodes must therefore use a smaller subnet mask than that used by the Switch

or other relevant network devices.

 RIP Setting: Disable RIP or use RIP-1 / RIP-2.

- 85 -

 Use Broadcast/Multicast: Specify how the routing table is sent out. RIP-1 can only use

broadcast. RIP-2 can use multicast to reduce network traffic.

 Advertise Routes: Enable or disable the Switch to advertise its own routing table.  Advertise Default Route: Enable or disable the Switch to advertise its own default route.  Accept RIP V1/V2 Updates: Configure the Switch to accept routing table from other routers.

Enabling RIP-1 can only accept RIP-1 update but enabling RIP-2 can accept RIP-1, RIP-2 or

RIP-1/RIP-2 updates.

 Use Split Horizon: This allows the Switch to never propagate routes back to an interface port

from which they have been acquired.

 Use Poisoned Reverse: This allows the Switch to propagate routes back to an interface port

from which they have been acquired, but set the distance vector metrics to infinity.

 Send Trigger Responses: If this configuration is Yes, whenever a route gets changed, the

Switch broadcast an update message after waiting for a short random delay, but without

waiting for the periodic cycle.
