Question

IP phones in VLAN 20 obtain IP addresses from the IOS DHCP server but fail to download their configuration and firmware from the TFTP server at 10.10.50.5. Data PCs in the same subnet get addresses and reach the network normally. The phone DHCP pool is configured with default-router and dns-server statements only. Which action will allow the phones to locate the TFTP server?

Accepted Answer

Add 'option 150 ip 10.10.50.5' to the DHCP pool so phones learn the TFTP server address

Answer
