Dimension GS-2024 Gigabit Ethernet Switch

Chapter 1

Getting to Know the GS-2024

This chapter describes the key features, benefits and applications of the GS-2024.

1.1 Introduction

The GS-2024 is a layer 2 stand-alone Gigabit Ethernet switch with 24 100/1000Mbps ports, two mini GBIC 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. From cabinet management to port­level control and monitoring, you can visually configure and manage your network via the web browser. Just click
your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the
console port, or third-party SNMP management.

TM

The GS-2024 also supports iStacking

technology, allowing management of 24 switches with one IP address.

1.2 Features

The next two sections describe the hardware and firmware features of the GS-2024.

1.2.1 Hardware Features

Power

The GS-2024 requires 100~240VAC/1.5A power.

24 100/1000 Mbps Gigabit Ports (with two paired with the mini GBIC ports)

Connect up to 24 computers or switches directly to the 100/1000Mbps auto-negotiating, automatic cable sensing
(auto MDI/MDIX) Gigabit ports. All ports support:

 IEEE 802.3/3u/3ab standards

 Back pressure flow control in half duplex mode

 IEEE 802.3x flow control in full duplex mode

Two Mini GBIC Slots

These are slots for mini GBIC (Gigabit Interface Converter) transceiver. These allow the GS-2024 to connect to
another WAN switch or daisy-chain to other switches.

Console Port

Use the console port for local management of the switch.

One Management Port

Use the RJ-45 management port for switch management only. The management port is out-of-band, meaning that it
does not carry switch traffic.

Fans

The two fans cool the GS-2024 sufficiently to allow reliable operation of the switch in even poorly ventilated
rooms or basements.

1.2.2 Firmware Features

IP Protocols

 IP Host (No routing)

 Telnet for configuration and monitoring

 SNMP for management

o SNMP MIB II (RFC 1213)

o Ethernet MIBs RFC 1643

o Bridge MIBs RFC 1493

o SMI RFC 1155

o RMON RFC 1757

o SNMPv2 or SNMPv2c

o Bridge extension MIBs RFC 2674

Management

 Web configurator

 Command-line interface locally via console port or remotely via Telnet

 Out-of-band RJ-45 management port

 SNMP

System Monitoring

 System status (link status, rates, statistics counters)

 SNMP

 Temperatures, voltage, fan speed reports and alarms

 Port Mirroring allows you to analyze one port’s traffic from another. This mechanism helps to track

network errors or abnormal packet transmission without interrupting the flow of data.

Security

 System management password protection  Port-based VLAN

 IEEE 802.1Q VLAN  802.1x Authentication

 Static MAC address

Port Link Aggregation

The GS-2024 adheres to the 802.3ad standard for static and dynamic port link aggregation.

1-2 Getting to Know the GS-2024

Dimension GS-2024 Gigabit Ethernet Switch

Bandwidth Control

 The GS-2024 supports rate limiting allowing you to create different service plans.

 The GS-2024 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.

 Broadcast storm control.

Quality of Service (QoS)

 Four priority queues so you can ensure mission-critical data is delivered on time.

 Follows the IEEE 802.1p priority setting standard.

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.

iStacking

ZyXEL iStacking™ allows an administrator to remotely manage multiple switches located in different areas. The
administrator can configure, monitor, troubleshoot and manage up to 24 switches at once with only one single IP,
regardless of the physical location. The switches must be directly connected and be in the same VLAN group so as
to be able to communicate with one another.

1.3 Applications

This section shows a few examples of using the GS-2024 in various network environments.

1.3.1 Backbone Application

In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.

The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch’s ports or connect other switches to the GS-2024.

In this example, all computers connected directly or indirectly to the GS-2024 can share super high-speed
applications on the Gigabit server.

To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.

Figure 1-1 Backbone Application

1.3.2 Bridging Example

In this example application the switch is the ideal solution for different company departments to connect 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. You can provide a super­fast uplink connection by installing the transceiver(s) in the mini GBIC slots on the GS-2024.

Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple
servers at a single location.

1-4 Getting to Know the GS-2024

Dimension GS-2024 Gigabit Ethernet Switch

Figure 1-2 Bridging Application

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 half­duplex operation.

1.3.3 High Performance Switched Workgroup Example

The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use
trunking to connect these two power workgroups.

Switching to higher-speed LANs such as FDDI or ATM 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 GS-2024 can provide the same bandwidth as FDDI and 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 1-3 High Performance Switched Workgroup Application

1.3.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. For more information
on VLANs, see the Switch Setup section and the VLAN Setup chapter in this User’s Guide. 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.

Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same 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.

Figure 1-4 VLAN Workgroup Application

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 3 while they
can belong to other VLAN groups too.
