CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
This User’s Guide covers the following models: ES-2108, ES-2108-F, ES-2108-LC, ES-2108G and ES-2108PWR. The following table lists features that are specific to the individual
models. The other features discussed in this chapter are common to all of the models covered
in this User’s Guide.
" See Appendix A on page 249 for detailed features and standards support.
Table 1 Model Specific Features
MODEL
FEATURE
Dual personality interface: a 1000BASE-T
copper RJ-45 port and a Small Form-Factor
Pluggable (SFP) slot (also called a mini-GBIC
slot), with one port active at a time

With its built-in web configurator, managing and configuring the Switch is easy. In addition,
the Switch can also be managed via Telnet, SSH (Secure SHell), any terminal emulator
program on the console port, or third-party SNMP management.
ES-2108 ES-2108-F ES-2108-LC ES-2108-G ES-2108PWR
1.1.1 Backbone Application
In this application, the Switch is an ideal solution for small networks where rapid growth can
be expected in the near future.

ES-2108 Series User’s Guide

Chapter 1 Getting to Know Your Switch
The Switch can be used standalone for a group of heavy traffic users. You can connect
computers directly to the Switch’s port or connect other switches to the Switch.
In this example, all computers can share high-speed applications on the server. To expand the
network, simply add more networking devices such as switches, routers, computers, print
servers etc.
Figure 1 Backbone Application
1.1.2 Bridging Example
In this example application the Switch connects different company departments (RD and
Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server
and network bottlenecks. All users that need high bandwidth can connect to high-speed
department servers via the Switch.
For ES-2108G, you can provide a super-fast uplink connection by using a Gigabit Ethernet/
mini-GBIC port on the Switch.
Moreover, the Switch eases supervision and maintenance by allowing network managers to
centralize multiple servers at a single location.
Figure 2 Bridging Application

ES-2108 Series User’s Guide
1.1.3 High Performance Switched Example
The Switch is ideal for connecting two networks that need high bandwidth. In the following
example, use trunking to connect these two networks.
Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not
feasible for most people due to the expense of replacing all existing Ethernet cables and
adapter cards, restructuring your network and complex maintenance. The Switch can provide
the same bandwidth as ATM at much lower cost while still being able to use existing adapters
and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.
Figure 3 High Performance Switched Application
Chapter 1 Getting to Know Your Switch
1.1.4 IEEE 802.1Q VLAN Application Examples
This section shows a workgroup and a shared server example using 802.1Q tagged VLANs.
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one group. A station can
belong to more than one group. With VLAN, a station cannot directly talk to or hear from
stations that are not in the same group(s) unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 8 on page 87.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain thus increase network
performance through reduced broadcast traffic. VLAN groups can be modified at any time by
adding, moving or changing ports without any re-cabling.
ES-2108 Series User’s Guide

Figure 4 Tag-based VLAN Application
1.1.4.2 VLAN Shared Server Example
Shared resources such as a server can be used by all ports in the same VLAN as the server, as
shown in the following example. In this example, only ports that need access to the server
need belong to VLAN 1. Ports can belong to other VLAN groups too.
Figure 5 Shared Server Using VLAN Example
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 4 on page 51.
• Command Line Interface. Line commands offer an alternative to the Web Configurator
and may be necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
See Section 26.8 on page 200.
• SNMP. The device can be monitored and/or managed by an SNMP manager. See Section
27.3 on page 204.

ES-2108 Series User’s Guide
Chapter 1 Getting to Know Your Switch
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch
more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the Switch to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the Switch. You could simply restore your last configuration.

4.6 Resetting the Switch
If you lock yourself (and others) from the Switch or forget the Switch password, you will need
to reload the factory-default configuration file or reset the Switch back to the factory defaults.
4.6.1 Reload the Factory-default Configuration File
Uploading the factory-default configuration file replaces the current configuration file with the
factory-default configuration file. This means that you will lose all previous configurations
and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no
parity, one stop bit and flow control set to none. The password will also be reset to “1234” and
the IP address to 192.168.1.1.
To upload the factory-default configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
Section 3.1.1 on page 43 for details.
2 Disconnect and reconnect the Switch’s power to begin a session. When you reconnect
the Switch’s power, you will see the initial screen.

7.4 Introduction to VLANs
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Devices on a logical network belong to one group. A device can
belong to more than one group. With VLAN, a device cannot directly talk to or hear from
devices that are not in the same group(s); the traffic must first go through a router.
ES-2108 Series User’s Guide
75
Chapter 7 Basic Setting
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security
among the subscribers. When properly configured, VLAN prevents one subscriber from
accessing the network resources of another on the same LAN, thus a user will not see the
printers and hard disks of another user in the same building.
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast
packets go to each and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.
" VLAN is unidirectional; it only governs outgoing traffic.
See Chapter 8 on page 87 for information on port-based and 802.1Q tagged VLANs.
7.5 Switch Setup Screen
Click Basic Setting > Switch Setup in the navigation panel to display the screen as shown.

Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use the following fields to configure the priority level-to-physical queue
mapping.
The Switch has eight physical queues that you can map to the eight priority levels. On the Switch,
traffic assigned to higher index queues gets through faster while traffic in lower index queues is
dropped if the network is congested.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d

7.7 Port Setup
Ethernet port connections can be in half-duplex or full-duplex mode. Full-duplex refers to a
device's ability to send and receive simultaneously , while half-duplex indi cates that t raffic can
flow in only one direction at a time. The Ethernet port must use the same speed or duplex
mode setting as the peer Ethernet port in order to connect.
80
ES-2108 Series User’s Guide
Chapter 7 Basic Setting
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 at half-duplex operation.
Auto-negotiation regulates the speed and duplex of each port, based on the capability of both
devices. When auto-negotiation is turned on, an Ethernet port on the Switch negotiates with
the peer automatically to determine the connection speed and duplex mode. If the peer
Ethernet port does not support auto-negotiation or turns off this feature, the Switch determines
the connection speed by detecting the signal on the cable and using half duplex mode. When
the Switch’ s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and
duplex mode when making a connection, thus requiring you to make sure that the settings of
the peer Ethernet port are the same in order to connect.
Use this screen to configure Switch port settings. Click Basic Setting > Port Setup in the
navigation panel to enter the port configuration screen.

For Ethernet ports, select Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half

For the Gigabit Ethernet/mini-GBIC slot, select Auto, 10M/Half Duplex, 10M/Full

For the mini-GBIC slot on the ES-2108-LC, select Auto or 1 000M/Full Duplex.
The port speed and the duplex mode are fixed (100M/Full Duplex) for the 100 Base-
FX fiber optic port on the ES-2108-LC and the Fast Ethernet SFP transceiver
connection on the ES-2108-F.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port
automatically to obtain the connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, a port on the Switch negotiates with the
peer automatically to determine the connection speed and duplex mode. If the peer
port does not support auto-negotiation or turns off this feature, the Switch determines
the connection speed by detecting the signal on the cable and using half duplex
mode. When the Switch’s auto-negotiation is turned off, a port uses the preconfigured speed and duplex mode when making a connection, thus requiring you to
make sure that the settings of the peer port are the same in order to connect.
Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer
memory causing packet discards and frame losses. Flow Control is used to regulate
transmission of signals to match the bandwidth of the receiving port.
The Switch uses IEEE802.3x flow control in full duplex mode and back-pressure flow
control in half duplex mode.
IEEE802.3x flow control is used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending signals when the receiving port
memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision"
signal to the sending port (mimicking a state of packet collision) causing the sending
port to temporarily stop sending signals and resend later. Select Flow Control to
enable it.

CHAPTER 8
VLAN
The type of screen you see here depends on the VLAN Type you selected in the Switch Setup
screen. This chapter shows you how to configure 802.1Q tagged and port-based VLANs.
8.1 Introduction to IEEE 802.1Q Tagged VLAN
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN
membership of a frame across bridges - they are not confined to the switch on which they were
created. The VLANs can be created statically by hand or dynamically through GVRP. The
VLAN ID associates a frame with a specific VLAN and provides the information that switches
need to process the frame across the network. A tagged frame is four bytes longer than an
untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the
type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts
after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet
switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not
be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID,
giving a possible maximum number of 4,096 (212) VLANs. Note that user priority and VLAN
ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a
priority frame, meaning that only the priority level is significant and the default VID of the
ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to
identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN
configurations are 4,094.

8.1.1 Forwarding Tagged and Untagged Frames
Each port on the Switch is capable of passing tagged or untagged frames. To forward a frame
from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the Switch first
decides where to forward the frame and then strips off the VLAN tag. To forward a frame from
an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the Switch first decides
where to forward the frame, and then inserts a VLAN tag reflecting the ingress port's default
VID. The default PVID is VLAN 1 for all ports, but this can be changed.

Chapter 8 VLAN
8.2 Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN membership across
switches.
8.2.1 GARP
GARP (Generic Attribute Registration Protocol) allows network switches to register and deregister attribute values with other GARP participants within a bridged LAN. GARP is a
protocol that provides a generic mechanism for protocols that serve a more specific
application, for example, GVRP.
8.2.1.1 GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values.
8.2.2 GVRP
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Enable this
function to permit VLANs groups beyond the local Switch.
Please refer to the following table for common GARP terminology.

8.3 Port VLAN Trunking
Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to
pass through that port. This is useful if you want to set up VLAN groups on end devices
without having to configure the same VLAN groups on intermediary devices.
Refer to the following figure. Suppose you want to create VLAN groups 1 and 2 (V1 and V2)
on devices A and B. Without VLAN Trunking, you must configure VLAN groups 1 and 2 on
all intermediary switches C, D and E; otherwise they will drop frames with unknown VLAN
group tags. However, wi th VLAN Trunking enabled on a port(s) in each intermediary switch
you only need to create VLAN groups in the end devices (A and B). C, D and E automatically
allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those
switches) to pass through their VLAN trunking port(s).

8.5 Static VLAN
Use a static VLAN to decide whether an incoming frame on a port should be
• sent to a VLAN group as normal depends on its VLAN tag.
• sent to a group whether it has a VLAN tag or not.
• blocked from a VLAN group regardless of its VLAN tag.
You can also tag all outgoing frames (that were previously untagged) from a port with the
specified VID.

8.6 Port Based VLAN Setup
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the device on which they were created.
" When you activate port-based VLAN, the Switch uses a default VLAN ID of 1.
You cannot change it.
In screens (such as IP Setup and Filtering) that require a VID, you must enter 1 as the VID.
The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN
with all Ethernet ports.
8.6.1 Configure a Port-based VLAN
Select Port Based as the VLAN Type in the Switch Setup screen (see Figure 40 on page 89)
and then click Advanced Application > VLAN in the navigation panel to display the next

Static MAC Forwarding
Use these screens to configure static MAC address forwarding.
9.1 Overview
A static MAC address is an address that has been manually entered in the MAC address table.
Static MAC addresses do not age out. When you set up static MAC address rules, you are
setting static MAC addresses for a port. This may reduce the need for broadcasting.
Static MAC address forwarding together with port security allow only computers in the MAC
address table on a port to access the Switch. See Chapter 17 on page 131 for more information
on port security.
9.2 Configuring Static MAC Forwarding
A static MAC address is an address that has been manually entered in the MAC address table.
Static MAC addresses do not age out. When you set up static MAC address rules, you are
