Introduction
The device manager is a graphical device management
tool that provides real-time views of the configuration and the performance
conditions for a single switch. It provides features such as Express
Setup to simplify switch management tasks. It also uses
graphical, color-coded displays such as a front panel view of the switch,
graphs, and animated indicators to simplify switch monitoring tasks.
Although extensive networking knowledge is not necessary, we recommend familiarity with LAN switch fundamentals. The Cisco Press General Networking Resources website has links to documents that provide internetworking overviews.
For comprehensive configuration and monitoring features,
use the Network Assistant or the switch command-line interface (CLI).
You can display the device manager from anywhere
in your network through a web browser such as Microsoft Internet Explorer. See the switch release notes for the system requirements
for running the device manager. The Support window provides a link to the
switch documentation.
Note: We recommend that you run the cryptographic
software image on the switch and use the device manager in a secured session. See Using Secured Sessions for information on protecting
your device manager session from unauthorized access.

Using the Front Panel View
The Front Panel view is a graphical display of the
switch front panel. The display shows all the switch components color-coded
according to their status. The colors can help you to quickly see if
a faulty condition or an error condition exists. See the
Legend for the meanings of the colors.
The Uptime field shows how long the switch has been
operating since it was last powered on or was restarted. Status is automatically
refreshed every 60 seconds or when you click
Refresh on the toolbar. The refresh counter shows the number
of seconds that remain before the next refresh cycle.
Move the pointer over a port to display the port
number, description, status, speed, and duplex mode. Note that the speed
and duplex mode for a port only appear in the pop-up window when a device
is connected to the port.
The Front Panel view also displays a graphical representation
of the internal ports to help you monitor their status by using the
device manager.
See the switch hardware installation guide for information
about the different ports on the switch, such as:
Console port
Internal 100-Mb/s
management port
Internal
1000-Mb/s downlink ports
External
10/100/1000-Mb/s uplink ports
The LED for the Ethernet Management (Fa0) port also matches the LED on the switch.
The system and port LEDs on the display match the
LEDs on the physical switch. To change the type of information displayed
through the port LEDs, choose a mode from the View list
or click the Mode button.

This list summarizes the information provided by
the LEDs on the Front Panel view. For more information about the LEDs,
see the
Legend or switch hardware installation
guide.

The LED, referred to as the System LED, shows the status of the switch (system). |
|
The LED, referred to as the Fault LED, shows if a system fault exists. |

Using the Menus

|
The device manager has options under
the Configure, Monitor, and Maintenance menus to help you monitor and
configure the switch:
The device manager
can execute basic configuration tasks at the switch and port levels.
The Configure menu options provide some simplified configuration tools
to set up the switch and its ports. The menu also provides an option
to restart and reset the switch. To save any changes that you make on
the configuration windows, you must click Submit. For more information,
see Port Settings, Express Setup, and Restart / Reset.
Note: The information on the configuration
windows is not automatically refreshed. Click
Refresh on the toolbar to update the information displayed on
these windows.
The device manager
receives, collects, and displays status and detailed, run-time statistics
every 60 seconds or when you manually refresh the system by clicking
Refresh on the toolbar. The Monitor menu options display this
data in graphs and tables. For more information, see Trends, Port Status, and Port Statistics.
The Maintenance menu
provides the Telnet option to display the switch CLI and the Software
Upgrade option to upgrade the switch software. For more information,
see Telnet and Software Upgrade.
In addition to the Configure, Monitor, and Maintenance
menu options, the menu provides these options:
The Dashboard displays the main window for monitoring
the switch status and the performance.
The Network Assistant displays
the link to the Cisco Network Assistant website on Cisco.com.

Using Secured Sessions
The switch uses the Secure Sockets Layer (SSL) protocol
to secure the HTTP communications between the switch and your network
management station. When you attempt to display the device manager,
this protocol
Authenticates the web-based
connection between the switch and your network management station.
Encrypts and decrypts
the information exchanged between the switch and your network management
station to protect the information from unauthorized access over the
Internet.
SSL is enabled by default on the switch. It is available
only on the cryptographic version of the switch software image.
When the device manager is first launched, it displays
a message that asks if you want a secured session with the switch. If
you choose Yes, the switch launches the device manager in secure
mode.
There are other ways to start a secured device manager session:
- Enter https:// before the switch IP address. (HTTP over
SSL is abbreviated as HTTPS.)
- Click the Session: Standard | Secured link at the top right corner of the device manager window.
There are several ways to determine whether your device manager session
is secured:
- Look at the URL in the browser Address field. A URL that starts
with https:// means that the session is secured through
SSL. A URL that starts with http:// means that the session
is not secured.
- Look at the Session: Standard | Secured link
at the top right corner of the device manager window.
- If the link appears as Session: Standard | Secured,
the switch is running a secured session.
- If the link appears as Session: Standard | Secured,
the switch is not running a secured session.
- Look for a locked padlock image at the bottom of your browser window. The locked padlock only appears if the session is secured.
Note: SSL is not supported on Telnet connections
with the switch. As a result, when you open a Telnet session from the
device manager, the transmission to and from the switch is not secure
even though the device manager might be running in secured mode. Be
careful with the information that you send through your Telnet sessions.
