26 Preface
Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1 Introduction
The switch is a stand-alone layer-2 Ethernet switch with eight 10/100Mbps ports. The ES2108-G and ES-2108PWR also includes one Gigabit/mini-GBIC port. The ES-2108-LC
provides one mini-GBIC slot and one 100 Base-FX fiber optic port for optical uplinking.
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 Series User’s Guide
CHAPTER 1
1.2 Software Features
This section describes the general software features of the switch.
DHCP Client
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the
switch as a DHCP client to obtain TCP/IP information (such as the IP address and subnet
mask) from a DHCP server. If you disable the DHCP service, you must manually enter the
TCP/IP information.
VLAN
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.
Differentiated Services (DiffServ)
With DiffServ, the switch marks packets so that they receive specific per-hop treatment at
DiffServ-compliant network devices along the route based on the application types and traffic
flow.
Chapter 1 Getting to Know Your Switch 27
ES-2108 Series User’s Guide
Queuing
Queuing is used to help solve performance degradation when there is network congestion.
Two scheduling services are supported: Strict Priority Queuing (SPQ) and Weighted Round
Robin (WRR). This allows the switch to maintain separate queues for packets from each
individual source or flow and prevent a source from monopolizing the bandwidth.
Port Mirroring
Port mirroring allows you to copy traffic going from one or all ports to another or all ports in
order that you can examine the traffic from the mirror port (the port you copy the traffic to)
without interference.
Static Route
Static routes tell the switch how to forward IP traffic when you configure the TCP/IP
parameters manually.
IGMP Snooping
The switch supports IGMP snooping enabling group multicast traffic to be only forwarded to
ports that are members of that group; thus allowing you to significantly reduce multicast
traffic passing through your switch.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between switches,
bridges or routers. It allows a switch to interact with other (R)STP -compliant switches in your
network to ensure that only one path exists between any two stations on the network.
Link Aggregation
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity
link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed
links than to under-utilize a high-speed, but more costly, single-port link.
Port Authentication and Security
For security, the switch allows authentication using IEEE 802.1x with an external RADIUS
server and port security that allows only packets with dynamically learned MAC addresses
and/or configured static MAC addresses to pass through a port on the switch.
Maintenance and Management Features
• Access Control
You can specify the service(s) and computer IP address(es) to control access to the switch
for management.
• Cluster Management
28 Chapter 1 Getting to Know Your Switch
Cluster management (also known as iStacking) allows you to manage switches through
one switch, called the cluster manager. The switches must be directly connected and be in
the same VLAN group so as to be able to communicate with one another.
• Configuration and Firmware Maintenance
You can backup or restore the switch configuration or upgrade the firmware on the
switch.
1.3 Hardware Features
This section describes the ports on the switch.
Ethernet Ports
The ports allow the switch to connect to another Ethernet devices.
Gigabit Ethernet Port
ES-2108 Series User’s Guide
Avaliable on the ES-2108-G and ES-2108PWR, the port allows the switch to connect to
another WAN switch.
Mini-GBIC Slot
Install SPF transceivers in this slot to connect to other Ethernet switches at longer distances
than the Ethernet port.
Console Port
Use the console port for local management of the switch.
PoE (Power over Ethernet)
The ES-2108PWR can provide power to a device (that supports PoE) such as an access point
or a switch through a 10/100Mbps Ethernet port.
1.4 Applications
This section shows a few examples of using the switch in various network environments.
1.4.1 Backbone Application
In this application, the switch is an ideal solution for small networks where rapid growth can
be expected in the near future.
Chapter 1 Getting to Know Your Switch 29
ES-2108 Series User’s Guide
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
1.4.2 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.
