Switch Management Interface

The NETGEAR GS716T and GS724T Smart Switches contain embedded Web server and management software for managing and monitoring switch functions. The switches function as a simple switch 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.

NETGEAR provides the Smart Control Center utility with this product. This program runs under Microsoft 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 19.

Windows® XP, Windows 2000, or Windows Vista® and provides a front end

Chapter 1: Getting Started | 11

GS716Tv2 and GS724Tv3 Software Administration Manual

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 13

• 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 15

• 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 16.

12 | Chapter 1: Getting Started

GS716Tv2 and GS724Tv3 Software Administration Manual

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.

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 the following figure.

6. Make a note of the displayed IP address assigned by the DHCP server. You will need this

value to access the switch directly from a Web browser (without using the Smart Control Center).

7. Select your switch by clicking the line that displays the switch, then click the

Web Browser Access button. The Smart Control Center displays a login window similar to

the following figure.

GS716Tv2 and GS724Tv3 Software Administration Manual

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.

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 GS716T and GS724T switch. The

utility broadcasts Layer 2 discovery packets within the broadcast domain to discover the switch. You should see a screen similar to Figure on page 13.

6. Select the switch, then click Configure Device. The page expands to display additional

fields at the bottom of the page, as the following figure shows.

7. Choose the Disabled radio button to disable DHCP.

8. Enter the static switch IP address, gateway IP address, and subnet mask for the switch, and

then type your password.

Tip: You must enter the current password every time you use the Smart

Chapter 1: Getting Started | 15

GS716Tv2 and GS724Tv3 Software Administration Manual

9. Click Apply to configure the switch with the network settings.

Please ensure that your PC and the switch are in the same subnet. Make a note of these settings for later use.

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 operating system, open the Internet Protocol (TCP/IP) properties screen that you access from the Local Area Connection properties, as shown in the following figure. You need Windows Administrator privileges to change these settings.

Windows®

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.

16 | Chapter 1: Getting Started

GS716Tv2 and GS724Tv3 Software Administration Manual

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 GS716T and GS724T.

2. Open a Web browser on your PC and connect to the management interface as described in

Web Access on page 18.

3. Change the network settings on the switch to match those of your network (this procedure is

described in IP Configuration on page 33).

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

Using SNMP

The switch software supports the configuration of SNMP groups and users that can manage traps that the SNMP agent generates.

switch switches use both standard public MIBs for standard functionality and private MIBs that support additional switch functionality. All private MIBs begin with a “-” prefix. The main object for interface configuration is in -SWITCHING-MIB, which is a private MIB. Some interface configurations also involve objects in the public MIB, IF-MIB.

SNMP is enabled by default. The System  Management  System Information Web page, which is the page that displays after a successful login, displays the information you need to configure an SNMP manager to access the switch.

Any user can connect to the switch using the SNMPv3 protocol, but for authentication and encryption, the switch supports only one user which is admin; therefore there is only one profile that can be created or modified.

To configure authentication and encryption settings for the SNMPv3 admin profile by using the Web interface:

1. Navigate to the System  SNMP  SNMPv3  User Configuration page.

2. To enable authentication, select an Authentication Protocol option, which is either MD5 or

SHA.
