Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1 Introduction
The ES-2024A is a stand-alone layer-2 Ethernet switch with 24 10/100Mbps ports and two
Gigabit Ethernet/mini-GBIC ports.
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.
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.
