EES-1024AF Intelligent Ethernet Switch

Preface

Congratulations on your purchase of the EES Series of Intelligent Ethernet Switches.

This preface introduces you to the EES Series and discusses the organization and conventions of this User’s Guide. It also provides information on other related documentation.

About The EES Series

The EES Intelligent Switch is designed to provide your network with Ethernet, Fast Ethernet, Gigabit Ethernet connectivity over twisted pair and fiber optic cabling. Two expansion slots on the front panel of the EES further add to the flexibility of your network systems. With its build-in Web Configurator, managing and configuring the EES becomes easier. From cabinet management to port-level control and monitoring, you can visually configure and manage your network via the web browser.

General Syntax Conventions

“Enter” means for you to type one or more characters and press the carriage return. “Select” or “Choose” means for you to select one from the predefined choices.

The SMT menu titles and labels are in Bold Times font. Predefined field choices are in Bold Arial font. Command and arrow keys are enclosed in square brackets. [ENTER] means the Enter, or carriage return key; [ESC] means the Escape key and [SPACE BAR] means the Space Bar.

For brevity’s sake, we will use “e.g.” as shorthand for “for instance”, and “i.e.” as shorthand for “that is” or “in other words” throughout this manual.

The EES-1024AF Intelligent Ethernet Switch will be referred to as the EES-1024AF, or simply as the switch in this manual.

1.4 Management Methods

The switch supports the following management methods:

• Console and Telnet Management

• Web configurator

• SNMP Network Management

1.4.1 Console and Telnet Management

Managing the switch through the console port requires a direct connection between the computer and the switch using the RS-232 console port. You can also telnet into the switch from any computer on your network (provided you know the IP address of the switch and are in the same subnet).

1.4.2 Web Configurator

The switch comes with an embedded HTML web configurator residing in flash memory. It offers advanced management features and allows you to manage the switch from anywhere on the network through a standard browser such as Microsoft Internet Explorer or Netscape Navigator. For more information, see Chapter 6 Using the

Web Configurator.

1-2 Getting to Know the EES 1024

EES-1024AF Intelligent Ethernet Switch

1.4.3 SNMP Network Management

Simple Network Management Protocol is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. This switch supports SNMP agent functionality, which allows a manager station to manage and monitor the switch through the network.

An SNMP managed network consists of two main components: agents and a manager.

An agent is a management software module that resides in a managed device (the switch). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices.

The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.

1.5 Network Applications

This section describes a few samples of network topology in which EES-1024AF Intelligent Switch (UTP/MTRJ/VF-45, Intelligent) is used.

The switch provides versatile configuration options for the network. It is ideally suited as a workgroup or segment switch in a network; it has the flexibility to provide switched 10Mbps network link to the desktop or shared hubs, aggregate traffic from workgroup switches, or provide dedicated 100Mbps or 1000Mbps (Gigabit) to servers with bandwidth-intensive applications. Since all Fast Ethernet ports are auto-negotiate for operation at 100 Mbps the switch is perfect for use in an evolving network environment where demand for network speed is increasing.

1.5.1 Backbone Application

For small networks where rapid growth can be expected in the near future, the switch is an ideal solution supporting backbone connectivity.

The switch can be used as a standalone switch for a group of heavy traffic users. Switching is brought to the desktop either through a single end-station per switch port or through a multi-port switch.

A 1000 Mbps server is connected to the switch providing end stations high-speed accessibility to its applications. This configuration provides dedicated 100 Mbps connections to the network center, to the server, and up to 40 users (while 2 Optional 8-port module are installed).

When the network needs expansion, you can simply connect the switch to any IEEE 802.3 ( Ethernet ), IEEE

802.3u ( Fast Ethernet ) and 802.3z ( Gigabit Ethernet ) compliant switch utilizing the Auto MDI/MDIX function. The switch can also work side by side with a wide range of networking devices (e.g., firewall routers and printer servers) added to the network.

EES-1024AF Intelligent Ethernet Switch

Figure 1-1 Backbone Application

1.5.2 Bridging Example

For enterprise networks where large data broadcasts are constantly processed, the switch is an ideal solution for department users to connect to the corporate backbone. Used as segment switch, the switch can alleviate user contention for bandwidth and eliminate server and network bottlenecks. All ports can connect to high-speed department servers that need high bandwidth. The switch provides parallel communications within its Gigabit port, which can run up to 2000 Mbps at full-duplex mode.

The switch makes key servers available to more users by allowing multiple conversations to occur concurrently, thereby significantly expanding overall network throughput. Moreover, the switch eases supervision and maintenance by allowing network manager centralize multiple servers at a single location.

1-4 Getting to Know the EES 1024

EES-1024AF Intelligent Ethernet Switch

Figure 1-2 Bridging Application

Full-duplex mode operation only applies to point-to-point access (for example, when attaching

the switch to a workstation, server, or another switch). When connecting to hubs, use a standard

cascaded connection set for half-duplex operation.

1.5.3 High Performance Switched Workgroup

The switch is ideal for connecting two workgroups, supporting the throughput, for example, of 800Mbps. This application is useful for power groups that need high bandwidth.

The most common LAN implementations use a combination of standard switches, bridges and routers. The bridges and routers quickly become bottlenecks, reducing overall network throughput. Switching to higher-speed LANs such as FDDI or ATM is not a good choice for most people. However, such broadband equipment is still extremely expensive and difficult to maintain. Besides, you have to replace all existing Ethernet cable and adapter cards, restructure your network, and implement more expensive administration procedures.

The switch can provide the same bandwidth of FDDI and ATM at much lower costs. In addition, all current adapters and network devices can still be used. The switching cross-domain connection is better than bridge and router because the current LAN structure can be retained in which any node can freely communicate with any other node.

1.5.4 IEEE 802.1Q VLAN Application

The switch supports up to 4095 tag-based IEEE 802.1Q-compatible virtual LAN (VLANs).

Tag-based VLAN Workgroup

You can group the switch ports into broadcast domains by assigning them to the same VLAN to increase network capacity and performance. With network segmentation, each switch port connects to a segment that is a single broadcast domain. Packets received in one VLAN can only be forwarded within that VLAN.

VLAN allows the logical grouping of end stations, based not on physical location but on business policies such as job function or department. Members of a group can be dispersed throughout a facility - they do not have to be connected in close physical locations.

Hence, group members can coordinate their data communication requirements regardless of the actual working locations; and the logical network can extend to any point you want it to. Moreover, VLAN groups can be modified at any time to add, move or change users without any re-cabling.

Shared Server

The switch’s compliance to the IEEE802.1Q tagging VLAN standard allows ports to exist in multiple VLANs for shared resources, such as servers, printers, or Switch-to-Switch connections. It is also possible to have resources exist in multiple VLANs on one switch as shown in the following figure.

In this example, stations in different VLANs share resources. As a result, VLAN 1 and VLAN 2 can access VLAN 3 for printing. All VLAN port members of VLAN3 can see the broadcasts from ports configured in VLAN3.
