ProSAFE Wireless Controller WC9500
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
screen.
 To configure another multicast IP address range and port for the firmware upgrade
process:
1. Select Maintenance > Upgrade > AP Upgrade Settings.
The AP Upgrade Settings screen displays.
2. Configure the settings as described in the following table
Setting Description
Start IP Enter the start IP address of the multicast range that the wireless controller should use.
End IP Enter the end IP address of the multicast range that the wireless controller should use.
Port Number Enter the port number that the wireless controller should use.
The default number is 69.
3. Click Apply.
Disable Multicast Firmware Upgrade
There might be network configurations in which you cannot use multicast. If you disable
multicast on the AP Upgrade Setting screen, the firmware upgrade process uses unicast,
which is a slower process because the firmware upgrade is applied to groups of access
points instead of simultaneously to all access points. The time that the unicast firmware
upgrade process takes depends on the network load and on the type of Ethernet interface to
which the wireless controller is connected.
 To disable multicast firmware upgrade for access points:
1. Select Maintenance > Upgrade > AP Upgrade Settings.
