ProSAFE Wireless Controller Configure Multicast Firmware Upgrade for Access Points When you add access points to the managed list (see Chapter 8, Discover and Manage Access Points), the wireless controller upgrades the firmware of the access points to the latest firmware that is loaded on the wireless controller. By default, this firmware upgrade process uses multicast, which allows all access points to be upgraded simultaneously. If you prefer, you can disable multicast and let the wireless controller use unicast for the firmware upgrade process (see Disable Multicast Firmware Upgrade on page 279). Also, if the multicast firmware upgrade process fails three times, the wireless controller automatically switches to the unicast firmware upgrade process. With the default multicast firmware upgrade process, the wireless controller distributes multicast IP addresses to the access points, enabling them to join the multicast group and to receive the firmware upgrade. Change the Multicast Firmware Upgrade Settings By default, the wireless controller uses IP range 239.255.0.0-239.255.0.255 for the multicast firmware upgrade process. If your network requires that the wireless controller uses a different multicast IP range, you can configure the IP range on the AP Upgrade Settings page. To configure another multicast IP address range and port for the firmware upgrade process: 1. Open a web browser, and in the browser's address field, type the wireless controller's IP address. By default, the IP address is 192.168.0.250. The wireless controller's login window opens. 2. Enter your user name and password. 3. Click the Login button. The wireless controller's web management interface opens and displays the Summary page. 4. Select Maintenance > Upgrade > AP Upgrade Settings. 5. Configure the settings as described in the following table. Maintain the Wireless Controller and Access Points 278
