Sorry not clear your comment, could you elaborate? What I am trying to do is to let the Cisco 7940 get the TFTP server address of 192.168.0.1.
The topology is just 2 devices interconnected by once lan cable: 1 Cisco 7940 and a Windows 10 laptop with DHCP server and TFTP sever on it. The windows 10 has the the IP 192.168.0.1 and It seemed 7940 has the IP of 192.168.0.2. I set the DHCP option 150 in the DHCP sever conf. But it seems not provisioned to phone.
Thanks!
