Setting Up Authentication Clients Configuring Authenticated VLANs
page 21-8 OmniSwitch 6600 Family Network Configuration Guide April 2006
with one authenticated VLAN. The address may be assigned dynamically if a DHCP server is located
in the network. DHCP is required in networks with multiple authenticated VLANs.
• Configure a DHCP server. Web browser clients may get IP addresses via a DHCP server prior to
authenticating or after authentication in order to move into a different VLAN. When multiple authenti-
cated VLANs are configured, after the client authenticates the client must issue a DHCP release/renew
request in order to be moved into the correct VLAN. Web browser clients automatically issue DHCP
release/renew requests after authentication. For more information, see “Setting Up the DHCP Server”
on page 21-29.
• Configure a DNS name on the switch. A DNS name must be configured so that users may enter a
URL rather than an IP address in the browser command line. For more information, see “Setting Up a
DNS Path” on page 21-29.
Configuring the Web Browser Client Language File
If you want the Web browser client to display the username and password prompts in another language,
modify the label.txt file with the desired prompts.
The label.txt file is available in the /flash/switch directory when you install the Hsecu.img file as
described in the next section.
The file may be edited with any text editor, and the format of the username and password prompts is as
follows:
Username="username_string"
Password="password_string"
Use the aaa avlan http language command to enable this file. For example:
-> aaa avlan http language
The label.txt file will be used for Web browser authentication clients.
Note. If you want to return to the default language (English) for the Web browser prompts, delete the
contents of the file.
Required Files for Web Browser Clients
Make sure the /flash/switch/avlan directory is available on the switch. The directory must be manually
installed using the install command to load Hsecu.img. The Hsecu.img file is available in the working
directory on the switch. When the Hsecu.img file is installed, the /flash/switch/avlan directory will be
available on the switch.
Important. When you install the Hsecu.img file after initial installation, any files in the /flash/switch/
avlan directory will be overwritten.
The /flash/switch/avlan directory contains authentication HTML pages for the client that may be modified
(to include a company logo, for example). The names of these files are: topA.html, topB.html,
bottomA.html, bottomB.html, and myLogo.gif.
The directory also contains files that must be installed on Mac OS Web browser clients as described in the
next sections.
