Cisco Small Business 300 Series Managed Switch Administration Guide 1

Getting Started

This section provides an introduction to the web-based configuration utility, and

covers the following topics:

• Starting the Web-based Configuration Utility

• Quick Start Device Configuration

• Interface Naming Conventions

• Window Navigation

Starting the Web-based Configuration Utility

This section describes how to navigate the web-based switch configuration utility.

If you are using a pop-up blocker, make sure it is disabled.

Browser Restrictions

• If you are using older versions of Internet Explorer, you cannot directly use

an IPv6 address to access the device. You can, however, use the DNS

(Domain Name System) server to create a domain name that contains the

IPv6 address, and then use that domain name in the address bar in place of

the IPv6 address.

• If you have multiple IPv6 interfaces on your management station, use the

IPv6 global address instead of the IPv6 link local address to access the

device from your browser.

Getting Started

Starting the Web-based Configuration Utility

Cisco Small Business 300 Series Managed Switch Administration Guide 2

Launching the Configuration Utility

To open the web-based configuration utility:

STEP 1 Open a Web browser.

STEP 2 Enter the IP address of the device you are configuring in the address bar on the

browser, and then press Enter.

NOTE When the device is using the factory default IP address of 192.168.1.254, its power

LED flashes continuously. When the device is using a DHCP assigned IP address or

an administrator-configured static IP address, the power LED is on solid.

Logging In

The default username is cisco and the default password is cisco. The first time

that you log in with the default username and password, you are required to enter

a new password.

NOTE If you have not previously selected a language for the GUI, the language of the Login

page is determined by the language(s) requested by your browser and the

languages configured on your device. If your browser requests Chinese, for

example, and Chinese has been loaded into your device, the Login page is

automatically displayed in Chinese. If Chinese has not been loaded into your

device, the Login page appears in English.

The languages loaded into the device have a language and country code (en-US,

en-GB and so on). For the Login page to be automatically displayed in a particular

language, based on the browser request, both the language and country code of

the browser request must match those of the language loaded on the device. If the

browser request contains only the language code without a country code (for

example: fr). The first embedded language with a matching language code is

taken (without matching the country code, for example: fr_CA).

To log in to the device configuration utility:

STEP 1 Enter the username/password. The password can contain up to 64 ASCII

characters. Password-complexity rules are described in the Setting Password

Complexity Rules section of the Configuring Security chapter.

STEP 2 If you are not using English, select the desired language from the Language drop-

down menu. To add a new language to the device or update a current one, refer to

the Upgrade/Backup Firmware/Language section.

Getting Started

Starting the Web-based Configuration Utility

STEP 3 If this is the first time that you logged on with the default user ID (cisco) and the

default password (cisco) or your password has expired, the Change Password

Page appears. See Password Expiration for additional information.

STEP 4 Choose whether to select Disable Password Complexity Enforcement or not.

For more information on password complexity, see the Setting Password

Complexity Rules section.

STEP 5 Enter the new password and click Apply.

When the login attempt is successful, the Getting Started page appears.

If you entered an incorrect username or password, an error message appears and

the Login page remains displayed on the window. If you are having problems

logging in, please see the Launching the Configuration Utility section in the

Administration Guide for additional information.

Select Don’t show this page on startup to prevent the Getting Started page from

being displayed each time that you log on to the system. If you select this option,

the System Summary page is opened instead of the Getting Started page.

HTTP/HTTPS

You can either open an HTTP session (not secured) by clicking Log In, or you can

open an HTTPS (secured) session, by clicking Secure Browsing (HTTPS). You are

asked to approve the logon with a default RSA key, and an HTTPS session is

opened.

NOTE There is no need to input the username/password prior to clicking the Secure

Browsing (HTTPS) button.

For information on how to configure HTTPS, see SSL Server.

Password Expiration

The New Password page appears:

• The first time you access the device with the default username cisco and

password cisco. This page forces you to replace the factory default

password.

• When the password expires, this page forces you to select a new

password.
