Using the IP Setup Utility Chapter 3 Configuring the Access Point for the First Time Using IPSU to Find the Access Point's IP Address If your access point receives an IP address from a DHCP server, you can use IPSU to find its IP address. Because IPSU sends a reverse-ARP request based on the access point MAC address, you must run IPSU from a computer on the same subnet as the access point. Follow these steps to find the access point's IP address: Step 1 Double-click the IPSU icon on your computer desktop to start the utility. The IPSU screen appears (see Figure 3-4). Figure 3-4 IPSU Get IP Address Screen Step 2 Step 3 When the utility window opens, make sure the Get IP addr radio button in the Function box is selected. Enter 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: 000164xxxxxx Note The MAC address field is not case-sensitive. Step 4 Step 5 Click Get IP Address. When the access point's IP address appears in the IP Address field, write it down. 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 from the default value using IPSU, refer to the "Using IPSU to Set the Access Point's IP Address and SSID" section on page 3-11. 3-10 Cisco Aironet 1200 Series Access Point Hardware Installation Guide OL-4310-01
