Getting to Know Your Switch

This chapter introduces the main features and applications of the switch.

1.1 Introduction

The ES-3148 is a stand-alone layer 2+ Ethernet switch with 48 10/100Mbps ports, two RJ-45
Gigabit ports for stacking and 2 dual personality interfaces for uplink as well as a console port
and a management port for local management. A dual personality interface includes one
Gigabit port and one slot for mini-GBIC transceiver (SFP module) 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, any terminal emulator program on the console port,
or third-party SNMP management.

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.
