Chapter 1

Starting a Web Browser Session

This chapter contains the procedures for starting, using, and quitting a web browser management session on the AT-GS950/16 switch. This chapter includes the following sections:

“Establishing a Remote Connection to the Web Browser Interface” on page 20

“Web Browser Tools” on page 23

“Quitting a Web Browser Management Session” on page 24

Chapter 1: Starting a Web Browser Session

Establishing a Remote Connection to the Web Browser Interface

The AT-GS950/16 switch is shipped with a pre-assigned IP address of 192.168.1.1.

After your initial login, Allied Telesis suggests that you assign a new IP address to your switch. To manually assign an IP address to the switch, refer to “Configuration of IP Address, Subnet Mask and Gateway Address” on page 26. To configure the switch to obtain its IP configuration from a DHCP server, refer to “DHCP Client Configuration” on page 35.

Whether you use the pre-assigned IP address or assign a new one, you must set your local PC to the same subnet as the switch.

To start a web browser management session, perform the following procedure:

1.Start your web browser.

2.In the URL field of the browser, enter 192.168.1.1. This is the default IP address of the switch. See Figure 1.

Configuration of IP Address, Subnet Mask and Gateway Address

This procedure explains how to change the IP address, subnet mask, and gateway address of the switch. Before performing the procedure, note the following:

A gateway address is only required if you want to remotely manage the device from a management station that is separated from the switch by a router.

To configure the switch to automatically obtain its IP configuration from a DHCP server on your network, go to “DHCP Client Configuration” on page 35.

To change the switch’s IP configuration, perform the following procedure:

1.From the main menu on the left side of the page, click the System folder.

The System folder expands.

2.From the System folder, select IP Setup. The IP Setup Page is displayed. See Figure 5.

Figure 5. IP Setup Page

3.Change the IP configuration parameters by observing or entering new information in the following fields:

System MAC Address - This parameter displays the MAC address of the switch. You cannot change this parameter.

System IP Address - Displays the current IP address of the switch. To change the IP address, enter a new IP address. When DHCP is enabled, you cannot change this parameter.

System Subnet Mask - Displays the current subnet mask of the switch. To change the subnet mask, enter a new subnet mask. When DHCP is enabled, you cannot change this parameter.

AT-GS950/16 Web Interface User Guide

System Default Gateway - Displays the default gateway of the switch. To change the default gateway, enter a new gateway. When DHCP is enabled, you cannot change this parameter.

DHCP Mode - For information about setting this parameter, refer to “DHCP Client Configuration” on page 35.

4. Click Apply.

Note

Changing the IP address ends your management session. To resume managing the device, enter the new IP address of the switch in the web browser’s URL field, as shown in Figure 1 on page 20.

5.After you log on to the switch with the new IP address, select Save Configuration to Flash from the main menu on the left side of the page to save the new IP address to memory.

Caution

If you do not select Save Configuration to Flash, the IP address will revert to its original setting when you power cycle or reboot the switch.
