What is the GUI?
The GUI (Graphical User Interface) is a web-based device management tool,
designed to make it easier to configure and monitor the switch. The GUI
provides an alternative to the CLI (Command Line Interface). Its purpose is to
make complicated tasks simpler and regularly performed tasks quicker.
The GUI relies on an HTTP server that runs on the switch, and a web browser
on the host PC. When you use the GUI to configure the switch, the GUI sends
commands to the switch and the switch sends the results back to your browser,
all via HTTP.
The tasks you may perform using the GUI are not as comprehensive as the
command set available on the CLI, but for some protocols, a few clicks of the
mouse will perform many commands.
The GUI is stored on the switch in the form of an embedded resource file, with
file extension rsc. Resource files are model-specific, with the model and
version encoded in the file name.
Accessing the Switch via the GUI
To use the GUI to configure the switch, you use a web browser to open a
connection to the switch’s HTTP server. Therefore, you need a PC, a web
browser and the switch. Supported browsers and operating systems, and the
settings you need on your PC and browser, are detailed in the following
section. Switch setup is detailed in “Establishing a Connection to the Switch” on
page 24.

Browser and PC Setup

The GUI requires a web browser installed on a PC. Table3 shows supported
combinations of operating system and browser. A copy of Internet Explorer can
be found on the switch’s Documentation and Tools CD-ROM.
