Using the IP Setup Utility (IPSU)

Objective

Using the IP Setup utility to find the Access Point IP address or to set IP address on the Access Point.

Criteria

  • Install the IPSU
  • Find the Access Point IP address
  • Use IPSU to set the IP address and the SSID

Installing the IPSU

Note  The IP Setup utility (IPSU) allows you to find the Access Point's IP address when it has been assigned by a DHCP server. You can also use IPSU to set the Access Point's IP address and SSID if they have not been changed from the default settings.

IPSU is on the Cisco Aironet Access Point CD, which shippped with each Access Point.

Note  IPSU is also available for downloading in the Software Center on Cisco.com.

To install the IPSU

  1. Put the Cisco Aironet Access Point CD in the CD-ROM drive of the computer you are using to configure the Access Point.
  2. Use Windows Explorer to view the contents of the CD. Double-click the IPSU folder, and then double-click the file called setup.exe. Follow the steps provided by the installation wizard.
  3. Double-click the IPSU icon on your computer desktop to start the utility.

Finding the Access Point 's IP address:

Note  If your Access Point receives an IP address from a DHCP server, use IPSU to find its IP address. Run IPSU from a computer on the same network as the Access Point.
 
Note  The MAC address field is not case-sensitive.

To find the Access Point's IP address

  1. Open utility window, make sure Get IP addr is selected in the Function box.
  2. Type the Access Point's MAC address in the Device MAC ID field. The Access Point's MAC address is printed on the label on the bottom of the unit. It should contain six pairs of hexadecimal digits. Your Access Point's MAC address might look like the following example: 004096xxxxxx
  3. Click Get IP Address.
  4. Write down the Access Point's IP address that appears in the IP Address field.
  5. To check the IP address, browse to the Access Point's browser-based management pages. Open an Internet browser.
  6. Type or paste the Access Point's IP address in the browser's location or address field.
  7. Press Enter. The Access Point's home page appears.

If IPSU reports that the IP address is 10.0.0.1, the default IP address, then the Access Point did not receive a DHCP-assigned IP address. To change the Access Point IP address using IPSU, refer to the following session "Setting the Access Point's IP Address and SSID".

Setting the Access Point's IP Address and SSID

If your Access Point does not receive an IP address from a DHCP server, or if you want to change the default IP address, you can use IPSU to assign an IP address. You can set the Access Point's SSID at the same time.

Note  The computer you use to assign an IP address to the Access Point must have an IP address of its own.
 
Note  IPSU can change the Access Point's IP address and SSID only from their default settings. After the IP address and SSID have been changed, IPSU cannot change them again.
 
Note  You cannot set the SSID without also setting the IP address.

To assign an IP address and an SSID to the Access Point:

  1. Double-click the IP Setup icon on your computer desktop. (If IPSU is not installed on your computer, follow the steps in the "Installing IPSU" section above to install it.)
  2. Open the utility window, make sure Set Parameters is selected in the Function box.
  3. Type the Access Point's MAC address in the Device MAC ID field. The Access Point's MAC address is printed on the label on the bottom of the unit. It should contain six pairs of hexadecimal digits. Your Access Point's MAC address might look like the following example: 004096xxxxxx
  4. Type the IP address you want to assign to the Access Point in the IP Address field.
  5. Type the SSID you want to assign to the Access Point in the SSID field.
  6. Click Set Parameters.
  7. To test the IP address, open an Internet browser.
  8. Type or paste the Access Point's IP address in the browser's location or address field.
  9. Press Enter. The Access Point's home page appears.
