Option 43:
When the AC (wireless controller) and the AP arenot in the same LAN, the AP cannot discover the AC through broadcast afterobtaining an IP address from the DHCP server. If you want to enable the AP todiscover the AC, you need to configure Option 43 carried in the DHCP responsepacket on the DHCP server.
Option 138:
Enter the IP address of the AC. Similar to Option43, when the AC and AP are not in the same LAN, you can configure Option 138 toenable the AP to obtain the IPv4 address of the AC.
Option 150:
Enter the IP address of the TFTP server. Enter the IP address of the TFTP server to specify the TFTP server address assigned tothe client. Multiple IP addresses can be entered and separated by spaces.
