28 Preface
Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1 Introduction
The GS-2024 is a stand-alone layer-2 Gigabit Ethernet switch with 24 100/1000Mbps ports
and two mini-GBIC (Gigabit Interface Converter) slots for optical uplinking and one console
port and RJ-45 port for local management.
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.
GS-2024 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 29
GS-2024 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 Scheduling (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.
Multicast VLAN Registration (MVR)
Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand
(MoD)) using multicast traffic across an Ethernet ring-based service provider network. MVR
allows one single multicast VLAN can be shared amoung different subscriber VLANs on the
network.
This improves bandwidth utilization with reduced multicast traffic in the subscriber VLANs
and easy multicast group management.
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.
