NTRODUCTION

This chapter describes the features of the 16-Port 10/100Mbps

Fast Ethernet Smart Switch and some background information about Ethernet/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. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them,

100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The nondisruptive and smooth evolutionary nature, and the dominant potential market base, virtually guarantee cost-effective and high performance Fast Ethernet solutions.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3

LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since

100Mbps Fast Ethernet is compatible with all other 10Mbps

Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training.

3

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the

Ethernet protocol transmitting among connected Ethernet or Fast

Ethernet LAN segments.

Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which don’t compete with each other for network transmission capacity.

The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.

Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required make routers relatively impractical.

Today switches are an ideal solution to most kinds of local area network congestion problems.

4

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if in a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and need for routers, using faster switching instead. Other VLAN features include:

¾ Security

Security is increased with the reduction of opportunity for eavesdropping on a broadcast network because data will be switched only to those users within the particular VLAN.

¾ Cost Reduction

VLANs can be used to create multiple broadcast domains, thus eliminating the need for expensive routers.

Port-based (or port-group) VLAN is the common method of implementing a VLAN, and is the one implimented in this Switch.

Each Switch port can belong to one or more of up to sixteen

VLANs.

Configuring the Switch

The 16-Port 10/100Mbps Fast Ethernet Smart Switch has a menu-driven console interface for smart switch configuration.

The Switch can be configured through the serial port. A network administrator can manage, control and monitor the switch from the console program. This section indicates how to configure the

Switch to enable its smart functions including:

¾ Setup

There are two items, Port Configuration and VLAN, shown in the

Setup screen. Each function of these two items will be illustrated in the following sections.

¾ System

In the System screen, Factory Reset, Change Password, Confirm

Password, Refresh Time, and Login Timeout, can be viewed and changed. System Uptime can’t be altered and is governed by the

Switch.

¾ File

The Switch can have its configuration file uploaded or downloaded by using Upload Configuration or Download

Configuration settings in the File setting screen.

¾ Statistics

In the Statistics menu screen, each port’s data transmit and receive status can be viewed, but not changed.

18

Login

First execute the terminal emulation program on the remote workstation, and turn on the Switch. When logging into the

Switch, the following screen (Figure 10) prompt appears:

Password:

Figure 10. Login

Insert the password into the blank space and then press Enter to log in to the Main Menu. If you are managing the Switch for the first time, you should input the factory default password “admin” to log in to the Switch. To change the password, first highlight

System Change Password to input your new password, and then highlight Confirm Password to input your new password again for confirmation.

19

Main Menu

The main menu appears, as shown in Figure 11. Note the console keys in the lower part of the display. Move to highlight a desired option by using Up Arrow, Down Arrow and Tab keys, and then press the Enter key to confirm. There are four options: Setup,

System, File, and Statistics, shown in the Main Menu screen.

Configuring Setup Menu

Note that there are two items, Port Configuration and VLAN, in

Setup menu as shown in Figure 12.

Figure 12. Setup Menu

¾ Port Configuration

In the Port Configuration menu (Figure 13), each port’s (inc. port

17: Fibre port) Speed, Flow Control, and QoS can be controlled.

Link Status is automatically determined by the Switch and can’t be shifted.

21

Figure 13. Port Configuration

(1) Speed

There are five modes— Auto, 100M Full, 100M Half, 10M Full, and 10M Half—for speed selections. To change the speed setting, highlight Port and enter the port number to select the desired port, next highlight Speed, click Enter, and use Space Bar to switch between the five different options.

(2) Flow Control

This setting determines whether or not the Switch will be handling flow control. To change the flow control setting, highlight Port and enter the port number to select the desired port.

Set FlowCtrl to ON for avoiding data transfer overflow, or set it to OFF where there is either no flow control, or this is handled by other hardware/software management.

(3) QoS

If some ports need to have priority for data management transfer, then QoS can be changed. QoS has two settings to choose from,

22

High and Low. The default setting for QoS on all ports is High.

To change the QoS setting, highlight Port and enter the port number to select the desired port. Set QoS as required to determine which ports will always transfer their data first.

(4) Link Status

This value is automatically determined by the Switch and can’t be changed. If there is a valid connection to the Switch through the indicated port, the Link Status will show the connection speed.

The status will be Down if there is no connection through that port.

¾ VLAN (Virtual Local Area Network)

Grouping of individual ports into a small “virtual” network of their own being independent of all other ports. To change the

VLAN, locate the port that needs to be set, select “V” for joining the VLAN group and “-” for not joining. The default setting of

VLAN is shown as Figure 14.

Figure 14. VLAN Configuration

23

For example, there are five computers (PC1~PC5) connected to the Switch’s port 1~5. They had been divided into two VLAN groups: VLAN1 (PC1~PC4) and VLAN2 (PC2~PC5). There is no way to connect PC1 and PC5, as shown in Figure 15. If PC1 has to connect to PC5, it should with it in the same VLAN.

Figure 15. There is no connection between PC1 and PC5

Using VLAN, the Switch can be divided into many independent small switches. For example, in Figure 16, the Switch has been divided into two VLAN groups. Both VLAN groups are independent and there’s no link between these VLAN groups.

The Switch can be regarded as two smaller switches.
