Chapter 1

Getting Started

This chapter provides an overview of starting your NETGEAR GS108T or GS110TP Smart Switch and accessing the user interface. It also leads you through the steps to use the Smart Control Center utility. This chapter contains the following sections:

•“Switch Management Interface” on page 1-1

•“Connecting the Switch to the Network” on page 1-2

•“Switch Discovery in a Network with a DHCP Server” on page 1-3

•“Switch Discovery in a Network without a DHCP Server” on page 1-5

•“Configuring the Network Settings on the Administrative System” on page 1-7

•“Web Access” on page 1-8

•“Smart Control Center Utilities” on page 1-9

•“Understanding the User Interfaces” on page 1-15

•“Interface Naming Convention” on page 1-21

Switch Management Interface

The NETGEAR GS108T and GS110TP Smart Switches contain an embedded Web server and management software for managing and monitoring switch functions. The GS108T and GS110TP function as simple switches without the management software. However, you can use the management software to configure more advanced features that can improve switch efficiency and overall network performance.

Web-based management lets you monitor, configure, and control your switch remotely using a standard Web browser instead of using expensive and complicated SNMP software products. From your Web browser, you can monitor the performance of your switch and optimize its configuration for your network. You can configure all switch features, such as VLANs, QoS, and ACLs by using the Web-based management interface.

v1.0, April 2010

GS108T and GS110TP Smart Switch Software Administration Manual

NETGEAR provides the Smart Control Center utility with this product. This program runs under Microsoft® Windows® XP, Windows 2000, or Windows Vista® and provides a front end that discovers the switches on your network segment (L2 broadcast domain). When you power up your switch for the first time, use the Smart Control Center to discover the switch and view the network information that has been automatically assigned to the switch by a DHCP server; or, if no DHCP server is present on the network, use the Smart Control Center to discover the switch and assign static network information.

In addition to enabling NETGEAR switch discovery, the Smart Control Center provides several utilities to help you maintain the NETGEAR switches on your network, such as password management, firmware upgrade, and configuration file backup. For more information, see “Smart Control Center Utilities” on page 1-9.

Connecting the Switch to the Network

To enable remote management of the switch through a Web browser or SNMP, you must connect the switch to the network and configure it with network information (an IP address, subnet mask, and default gateway). The switch has a default IP address of 192.168.0.239 and a default subnet mask of 255.255.255.0.

Use one of the following three methods to change the default network information on the switch:

•Dynamic assignment through DHCP—DHCP is enabled by default on the switch. If you connect the switch to a network with a DHCP server, the switch obtains its network information automatically. You can use the Smart Control Center to discover the automatically-assigned network information. For more information, see “Switch Discovery in a Network with a DHCP Server” on page 1-3

•Static assignment through the Smart Control Center—If you connect the switch to a network that does not have a DHCP server, you can use the Smart Control Center to assign a static IP address, subnet mask, and default gateway. For more information, see “Switch Discovery in a Network without a DHCP Server” on page 1-5

•Static assignment by connecting from a local host—If you do not want to use the Smart Control Center to assign a static address, you can connect to the switch from a host (administrative system) in the 192.168.0.0/24 network and change the settings by using the Web-based management interface on the switch. For information about how to set the IP address on the administrative system so it is in the same subnet as the default IP address of the switch, see “Configuring the Network Settings on the Administrative System” on page 1-7.

Switch Discovery in a Network with a DHCP Server

This section describes how to set up your switch in a network that has a DHCP server. The DHCP client on the switch is enabled by default. When you connect it to your network, the DHCP server will automatically assign an IP address to your switch. Use the Smart Control Center to discover the IP address automatically assigned to the switch.

To install the switch in a network with a DHCP server, use the following steps:

1.Connect the switch to a network with a DHCP server.

2.Power on the switch by connecting its AC-DC power adapter. For the GS108T, you can also power on the switch by connecting Port 1 to a PoE Power Sourcing Equipment (PSE).

3.Install the Smart Control Center on your computer.

4.Start the Smart Control Center.

5.Click Discover for the Smart Control Center to find your switch. You should see a screen similar to the one shown in Figure 1-1.

Switch Discovery in a Network without a DHCP Server

This section describes how to use the Smart Control Center to set up your switch in a network without a DHCP server. If your network has no DHCP service, you must assign a static IP address to your switch. If you choose, you can assign it a static IP address, even if your network has DHCP service.

To assign a static IP address:

1.Connect the switch to your existing network.

2.Power on the switch by plugging in the AC-DC power adapter. For the GS108T, you can also power on the switch by connecting Port 1 to a PoE PSE.

3.Install the Smart Control Center on your computer.

4.Start the Smart Control Center.

5.Click Discover for the Smart Control Center to find your GS108T or GS110TP switch. The utility broadcasts Layer 2 discovery packets within the broadcast domain to discover the switch.You should see a screen similar to Figure 1-1 on page 1-3.

Configuring the Network Settings on the Administrative System

If you choose not to use the Smart Control Center to configure the network information on the switch, you can connect directly to the switch from an administrative system, such as a PC or laptop computer. The IP address of the administrative system must be in the same subnet as the default IP address on the switch. For most networks, this means you must change the IP address of the administrative system to be on the same subnet as the default IP address of the switch (192.168.0.239).

To change the IP address on an administrative system running a Microsoft® Windows® operating system, open the Internet Protocol (TCP/IP) properties screen that you access from the Local Area Connection properties, as shown in Figure 1-5. You need Windows Administrator privileges to change these settings.

GS108T and GS110TP Smart Switch Software Administration Manual

Warning: When you change the IP address of your administrative system, you will loose your connection to the rest of the network. Be sure to write down your current network address settings before you change them.

To modify the network settings on your administrative system:

1.On your PC, access the MS Windows operating system TCP/IP Properties.

2.Set the IP address of the administrative system to an address in the 192.168.0.0 network, such as 192.168.0.200. The IP address must be different from that of the switch but within the same subnet.

3.Click OK.

To configure a static address on the switch:

1.Use a straight-through cable to connect the Ethernet port on the administrative system directly to any port on the GS108T or GS110TP.

2.Open a Web browser on your PC and connect to the management interface as described in “Web Access” on page 1-8.

3.Change the network settings on the switch to match those of your network (this procedure is described in “IP Configuration” on page 2-3).

After you change the network settings on the switch, return the network configuration on your administrative system to the original settings.

Web Access

To access the GS108T or GS110TP management interface, use one of the following methods:

•From the Smart Control Center, select the switch and click Web Browser Access.

•Open a Web browser and enter the IP address of the switch in the address field.

You must be able to ping the IP address of the GS108T or GS110TP management interface from your administrative system for Web access to be available. If you used the Smart Control Center to set up the IP address and subnet mask, either with or without a DHCP server, use that IP address in the address field of your Web browser. If you did not change the IP address of the switch from the default value, enter 192.168.0.239 into the address field.

Clicking Web Browser Access on the Smart Control Center or accessing the switch directly from your Web browser displays the login screen in Figure 1-6 on page 1-9.

•Change Password—Allows you to set a new password for the device. In this process, you are required to enter the old password and to confirm the new one, which can contain up to 20 ASCII characters.

From the Maintenance tab, you can upload or download a switch configuration file and upgrade the switch firmware.

Configuration Upload and Download

When you make changes to the switch, the configuration information is stored in a file on the switch. You can backup the configuration by uploading the configuration file from the switch to an administrative system. You can download a saved configuration file from the administrative system to the switch. The configuration file you download to the switch overwrites the running configuration on the switch.

Configuration upload and download is useful if you want to save a copy of the current switch configuration (Upload Configuration) before you make changes. If you do not like the changes, you can use the Download Configuration option to restore the switch to the settings in the saved configuration file.

To save a copy of the current switch configuration on your administrative system:

1.Click the Maintenance tab and select the device with the configuration to save.

2.Click Upload Configuration.

3.From the Browse for Folder window that appears, navigate to and select the folder where you want to store the configuration file.
