Chapter 2 Setting Up the Switch

Set Up the Switch (Existing Network)

Step 5

You can now manage the switch through the Cisco Configuration Assistant and the device manager.

We strongly recommend that you download the Cisco Configuration Assistant from Cisco.com and use it to manage the switch. You can download it from the CD-ROM that ships with the switch or from this Cisco.com site:

http://www.cisco.com/go/configassist

You can display the device manager by following these steps:

1.Start a web browser on your PC or laptop.

2.Enter the switch IP address, username, and password in the web browser, and press Enter. The device manager page appears.

If you do not know the switch IP address, you can display the device manager and find out the switch IP address by following the procedure in the “Access Direct Managed Mode” section on page 7-6.

Troubleshooting:

If the device manager does not appear, make sure that you entered the correct switch IP address in the browser.

If you entered the correct switch IP address in the browser, make sure that the switch and your PC or laptop are in the same network or subnetwork. For example:

•If your switch IP address is 172.20.20.85 and your PC or laptop IP address is 172.20.20.84, both devices are in the same network.

•If your switch IP address is 172.20.20.85 and your PC or laptop IP address is 10.0.0.2, the devices are in different networks and cannot directly communicate without a router. You must either change the switch IP address or change the PC or laptop IP address.

Tip We recommend running a secured session with the switch. See the “Secured Sessions with the Switch” section on page 2-12for information on how to ensure that your management session with the switch is protected from unauthorized access.
