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-GS950/24 switch. This chapter
includes the following sections:

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

page 24

 “Web Browser Tools” on page 27
 “Quitting a Web Browser Management Session” on page 28

Chapter 1: Starting a Web Browser Session

Switch’s IP Address

Establishing a Remote Connection to the Web Browser Interface

The AT-GS950/24 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 IPv4 Address, Subnet Mask and Gateway
Address” on page 32. To configure the switch to obtain its IP configuration
from a DHCP server, refer to “DHCP Client Configuration” on page 53.

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.

Figure 1. Entering a Switch’s IP Address in the URL Field

The A T -S115 Management Software displays the lo gin dialog box. See
Figure 2.

24

Figure 2. Management Login Dialog Box

3. Enter the AT-S115 management login user name and password.

AT-GS950/24 Web Interface User Guide

Note

The default user name is “manager” and the default password is
“friend.” The login name and password are case-sensitive.

4. Press OK.
The AT-GS950/24 Switch Information page is displayed. See Figure 3.

To change the user name and password, refer to “User Name and
Password Configuration” on page 42.

Figure 3. AT-GS950/24 Switch Information Page

The main menu appears on the left side and is common for all of the
management pages discussed in this guide. It consists of the following
folders and web pages:

 Switch Info
 Front Panel
 System

 Physical Interface
 Bridge
 SNMP
 Access Control
 RMON
 Voice VLAN
 Security
 DHCP Snooping
 LLDP
 Statistics Chart
 Tools
 Save Settings to Flash

menu on the left side of the page.
The AT-S115 Management software displays the front of the switch.

Ports are green that have a link to an end node. Ports without a link
are grey. To view the status of the ports for an MSTP instance, select
the instance from the MST Instance ID drop-down menu. The AT­GS950/24 switch front panel page is shown in Figure 4.

Figure 4. Front Panel Page

A web browser management session remains active even if you link to
other sites. You can return to the management web pages anytime as long
as you do not quit your browser session or the management session does
not time out. The default time-out is 10 minutes.

26

Web Browser Tools

You can use the web browser tools to move around the management
pages. Selecting Back on your browser’s toolbar returns you to the
previous display. You can also use the browser’s Bookmark feature to
save the link to the switch.

Chapter 2: System Configuration

Note

System Management Information

This section explains how to assign a name, location, and contact
information for the AT-GS950/24 switch. This information helps in
identifying each specific AT-GS950/24 switch among other switches in the
same local area network. Entering this information is optional.

Allied Telesis recommends that you assign a name to the switch.
Naming each switch can help you identify the specific switch you
want to manage among others. It can also help to avoid performing
a configuration procedure on the wrong switch.

To set a switch’s administration information, 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 Management.
The Management Page is displayed. See Figure 5 for the
AT-GS950/24 Management Page.

Figure 5. AT-GS950/24 Management Page

3. Configure the following parameters as necessary:

System Description - Indicates the Allied Telesis switch model.
You cannot change this parameter.

System Object ID - Indicates the unique SNMP MIB object
identifier that identifies the switch model. You cannot change this
parameter.
