Chapter 1

Getting

The EES-1024AF 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 switch
further add to the flexibility of your network systems.

The switch is a combination of 24 10/100M Ethernet RJ-45 ports and two optional module slots. The two optional
modules can be 8-Port 10/100 auto-sensing Intelligent Switch Module, 2/4/8-Port 100 Base-FX Intelligent Fiber
Module, Gigabit 1000Base-T Intelligent Switch Modules, and Gigabit 1000Base-SX/LX Intelligent Fiber Modules.

With its built-in web configurator, managing and configuring the switch becomes easier. From cabinet management
to port-level control and monitoring, you can visually configure and manage your network via the web browser.
Just click your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via
Telnet, the console port, or third-party SNMP 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.

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.

Figure 1-3 High Performance Switched Workgroup Application

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.

1-6 Getting to Know the EES 1024

EES-1024AF Intelligent Ethernet Switch

Figure 1-4 VLAN Workgroup Application

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.

Getting to Know the EES 1024 1-7

EES-1024AF Intelligent Ethernet Switch

Figure 1-5 Shared Server

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.

This chapter introduces the basics of SMT.

the SMT

4.1 Connecting to the Console Port

The Console configuration (out of band) allows you to set your switch to enable a user at a remote console terminal
to communicate with the switch as if the console terminal were directly connected to it.

The Console port uses a male DB-9 connector to connect to a computer or terminal for monitoring and configuring
the switch. Use the supplied RS-232 cable with a female DB-9 connector to connect a terminal or computer to the
Console port.

Figure 4-1 Connecting the Switch to a terminal via RS-232 cable

This section introduces the configuration and functions of the Web Configurator.

the Web Configurator

6.1 Introduction

The embedded Web Configurator 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 Navigator.

The Web Configurator supports Internet Explorer 4.0 and Netscape Communicator 4.x and later versions. It is
based on Java Applets with an aim to reduce network bandwidth consumption, enhance access speed and present an
easy viewing screen.

By default, Internet Explorer 4.0 does not allow Java Applets to open sockets. The user has to

explicitly modify the browser setting to enable Java Applets to use network ports. See Appendix

A Microsoft Internet Explorer Setup. You don’t need to change any configuration if you use

Netscape browser. However, Netscape browser doesn’t support TFTP firmware upgrade.

6.2 System Login

Disconnect the Console port connection before launching the Web Configurator.

Step 1. Start Internet Explorer or Netscape Communicator web browser.

Step 2. Type http:// and the IP address of the switch ( for example, the default is 192.168.1.1 ) in the Location or

Address field. Press Enter.

Step 3. The Password screen appears. Type user name and password. The default is root for both.

7.3 VLAN ( Virtual LAN )

A VLAN ( Virtual LAN ) is a group of switching ports designated by the switch as belonging to the same broadcast
domain. This feature allows the workgroup to be defined on the basis of their logical location instead of their
physical location, and this does not require recalling.

If a broadcast packet is received from a port, it will forward this broadcast packet only to those ports belonging to
the same VLAN. VLAN classification of every packet is done in the following way: If the packet is tagged with
non-zero VLAN-id field then this is used as the VLAN id. Otherwise the default VLAN id of the input port is used.
You can assign a single switch port to two or more VLANs. The factory default VLAN is that all ports belong to
the same VLAN group 1. VLAN also enable you to configure tag-based VLANs to help isolate broadcast traffic
and increase security. Creating VLANs increases network flexibility by allowing you to reassign devices to
accommodate network moves, additions, and changes, eliminating the need to change physical cabling.

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

VLAN and then click Apply once to configure the desired VLANs you want.

If you want to set multiple VLANs, we recommend that you set Default VLAN ID for each port first

in Ports page.

7.4 Trunk

Port trunking is the ability to group several 10/100Base-TX or 100Base-FX ports to increase the bandwidth
between this switch and another compatible switch. This is an inexpensive way to increase bandwidth. We define
port trunking as the ability to group sets of ports (up to 8) within the same module into a single logical link. The
port trunk acts as a single link between switches. Multiple trunks may be implemented in this switch, but only one
trunk can be created within a module.

Figure 7-4 Web Configurator - Trunk

You can add, edit and remove port members of each trunk by clicking the selection box under each port and then
click Apply.

Make sure trunking ports are in the same VLAN group.

EES-1024AF Intelligent Ethernet Switch

7.5 STP (Spanning Tree Protocol)

Spanning tree is a link management protocol that provides path redundancy while preventing undesirable loops in
the network. For Layer 2 Ethernet network to function properly, only one active path must exist between two
stations.

The spanning-tree algorithm calculates the best loop-free path throughout a switched network. STP forces
redundant data paths into a standby (blocked) state. If a network segment in the spanning tree fails and a redundant
path exists, the spanning-tree algorithm recalculates the spanning tree topology and activates the standby path.

Figure 7-5 Web Configurator - STP

Select Enable Spanning Tree Protocol to enable this feature.

7-6 Advanced Web Management

EES-1024AF Intelligent Ethernet Switch

Table 7-4 STP Fields Descriptions

FIELD DESCRIPTION

The Current Spanning Tree Root describes the unique root switch information for the instance of
spanning tree.

MAC Address The MAC address of the root switch.

Root Max Age The amount of time (in seconds) the protocol information received on a port is stored

by the root switch.

Root Hello Time The time interval (in seconds) the root switch sends Hello messages to other

switches.

Root Forward
Delay

The amount of time (in seconds) a port will remain in the listening or learning states

before entering the forwarding state.

Root Path Cost The path cost to the root switch from this switch.

Root Port The port providing the best path from the switch to the root switch.

The Spanning Tree Bridge Configuration describes this switch information in the spanning tree.

Priority The priority of the switch, default is 32768. The lower the numeric value you assign ,

the higher priority for this switch.

Max Age The amount of time (in seconds) protocol information received on a port is stored by

the root switch, the default value is 20

Hello Time How often the root switch broadcasts Hello message to other switches, the default

value is 2

Forward Delay The amount of time a port will remain in the listening and learning states before

entering the forwarding state, the default value is 15

The Port Configuration describes those ports information in this switch in the spanning tree.

Module Shows the module number of the specific port.

Port Shows the port number.

Trunked Indicates the port is trunked or not.

Priority The port priority. The smaller this value, the higher priority this port has.

State This state of this port. Each port on a switch using STP exists in one of the following

five states: Listening, Learning, Forwarding, Blocking or Disabled

Path Cost The cost of transmission through this port. The smaller this value, the higher cost this

port has. 4 for Gigabit Ethernet and 10 for Fast Ethernet and FDDI

Root Cost The cost of transmission to the root switch.

When you enable the spanning tree protocol, because all ports in the switch will listen and learn,

you may lose communication to the switch you are managing. Wait about 2 times forward delay

(i.e. 2*15 seconds) before you get the communication again.

Advanced Web Management 7-7

EES-1024AF Intelligent Ethernet Switch

7.6 Port Security

When a computer accesses a port on the switch, the MAC address of that computer is entered in the MAC address
table of that port. Port Security allows you to restrict the number of MAC addresses residing in a port. For example,
if a dummy extension hub is attached to a port on the switch, you can set up the port to allow only two users to
access. Use the port security window to set the parameters.

Step 1. Specify a number from one to 127 in the Max Allowed MAC Address Count Per Port field to set the

maximum MAC address for all ports.

Figure 7-6 Web Configurator – Port Security

To restrict the number of MAC address of a port, you must do the following:

Step 2. Select Enable for that port. If the Enable checkbox is not selected, there is no MAC address count

restriction for that port.

Step 3. Type the number in the Max Allowed MAC Address Count field for each individual port. This number

should be smaller than Max Allowed MAC Address Count Per Port.

Step 4. Click Apply.

Step 5. Used Count field tells you how many MAC address are residing in the corresponding port now.

A trunked port is not allowed to enable the port security option.

7-8 Advanced Web Management

EES-1024AF Intelligent Ethernet Switch

7.7 Port Priority – 802.1p

There are two priority queues ( high and low ) on each port. Each port arbitrates between two transmit queues (high
and low priority). The arbitration uses weighted round-robin between the high and low priority queues, and you can
adjust this weight.

7.7.1 Programmable Mapping of 802.1p to Internal Priority

The received packets with 802.1q tag are assigned priority according to a flexible (fixed for the old 48310 and
48320 module) and programmable mapping of the 802.1p user-priority tag (3 bits, value from 0 to 7) to the internal
priority queue. The default is to assign a packet to high priority queue when the 802.1p user-priority tag is 4 to 7,
and to low priority queue when the 802.1p user-priority tag is 0 to 3. Check the corresponding mapping checkbox
to assign a high priority or uncheck that to assign a low priority.

Figure 7-7 Web Configurator - Port Priority (802.1)

7.8 Port Priority - Type of Service

Each port can parse the header of an incoming IPv4 header and identify the Type-Of-Service byte (TOS field). This
is extremely important with the deployment of Microsoft Windows 2000 and the emerging DiffServ standard,
which marks Voice-Over-IP and other real-time traffic using this field. This feature provides Layer 3 QoS.

If this function of a port is enabled, then the most significant 6 bits of the TOS (these 6 bits are also known as the
DiffServ Code Point "DSCP" field, value from 0 to 63) are used to assign a priority to the packet received from this

Advanced Web Management 7-9

EES-1024AF Intelligent Ethernet Switch

port. Please check the corresponding mapping checkbox to assign a high priority or uncheck that to assign a low
priority. The old 48310 and 48320 modules do not support this function.

Figure 7-8 Web Configurator - Port Priority (IPv4 Type of Service)

7.9 IGMP (IP Multicast)

Multicasting is used to support real-time applications such as video conferencing or streaming audio. IGMP (
Internet Group Management Protocol ) allow you to query for any attached hosts who want to receive a specific
multicast service. The switch looks up the IP Multicast Group used for this service and adds any port which
received a similar request to that group. It then propagates the service request on to any neighboring multicast
switch to ensure that it will continue to receive the multicast service.

If you want your switch to support multimedia and IP multicast, enable this option (default is enabled). When this
option is enabled, this switch only directs the multicast data packets to the ports where needed, saving bandwidth. If
Forward with high priority is enabled, then the IP multicast traffic will have a higher priority than other traffic.

7.10 Static Address

You can lock a certain MAC address ( associated with a host, ) to a certain port. Once the MAC address is locked to
a specific port, this MAC address will not receive any packets if it is moved to another port. Static addresses are
manually entered into the Static Address Table.

Step 1. Enter the MAC address in the MAC Address field (ex. 00-00-00-00-00-01) and VLAN ID (default is 1).

Step 2. Select the Module and Port you want to associate with this entry with from the Port drop-down box.

Step 3. Click Add and then the Apply button.

Remove the entry from current static address table to unlock a MAC address from the select port; this MAC address
is free again. Click Remove All to delete all entries from the Static Address Table.

7.11 Broadcast Storm Filter

Storm filter avoids flooded data packets. This feature prevents the bursts of broadcast traffic. Excessive broadcast
packets ( Broadcast Storms ) can be filtered out by enabling the Broadcast Storm Filtering option. When this
option is enabled, if more than 3000 packets per second broadcast packets were sent to a port for 5 seconds, the port
will not receive any broadcast packets until less than 3000 packets per second broadcast packets were received for 5
seconds. If a broadcast storm happens to a port, you will see a red BS text appearing in the corresponding (module,
port) cell. A “—” indicates no broadcast storm.

7.12 Port Mirror (Sniffer)

Port Mirror (Sniffer) mirrors traffic (all frames) from a specific resource port to a target port. This helps tracking
down network errors or erroneous packet transfers without interrupting the flow of data across the network. If you
want to monitor all received and transmitted packets of a specific port, follow the steps below:

Step 1. Select the monitored port from the Mirror Source Port drop-down list in the corresponding Mirror

Source Module. Only one port can be monitored in one module at the same time.

Step 2. Select the corresponding target module port in Mirror Target Module and Mirror Target Port drop-

down lists.

Step 3. Select Enable for the corrosponding ports and then click Apply.

7.14 SNMP

You can manage the switch using a third-party SNMP ( Simple Network Management Protocol ) agent. The
community strings control the access rights to the SNMP agent.

Type the system name, system location and system contact in the corresponding fields. See the section on Home for
descriptions of these fields.

You can submit community strings on Get Request Community, and Set Request Community to authorize
management access. For security you should change them to prevent unauthorized access.

Get Request Community ( Read-only access right ) means that member of community can view the information
but can not make changes to the configuration.

Set Request Community ( Read/Write access right ) allow the member of the community to view and make
change to the configuration.

To set the Get Request Community and Set Request Community names, type the desired text string in the
corresponding fields. The default value for both fields is public. You must set these two parameters correctly to
perform Get request from the management unit and Set request to the management unit.
