Cisco 500 Series Stackable Managed Switch Administration Guide 1
Getting Started
This section provides an introduction to the user interface, and covers the
following topics:
•Starting the Web-based Switch Configuration Utility
•Quick Start Switch Configuration
•Interface Naming Conventions
•Window Navigation
Starting the Web-based Switch 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.
Browsers have the following restrictions:
•If you are using Internet Explorer 6, you cannot directly use an IPv6 address
to access the switch. 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.
•In Firefox, the automatic pop-up on top option is disabled by default. Certain
add-ons enable this feature during installation. To disable this option, go to
Tools -> Options. Click on the Content Tab and then click on Enable JavaScript, then
Advanced. Select the option Raise or lower windows.
•If you have multiple IPv6 interfaces on your management station, use the
IPv6 global address instead of IPv6 link local address to access the switch
from your browser.
