Scroll down until your see option 150 and check the box, and finally enter in the IP address(es) of your TFTP server(s) and you should be good to go.Now you will need to right click Scope Options under your scope and choose “Configure Scope Options…”
#Dhcpd tftpserver option windows
Once done, OK through the Predefined Options windows until you are back at DHCP Manager.Possible values (taken directly from RFC2132) are: 1 DHCPDISCOVER 2 DHCPOFFER 3 DHCPREQUEST 4 DHCPDECLINE 5 DHCPACK 6 DHCPNAK 7 DHCPRELEASE 8 DHCPINFORM This option is not user configurable. I always enter in the information exactly as shown below, but honestly the Option number, type as IP address and array checked are the only things that matter, the rest you set as you like. This option, sent by both client and server, specifies the type of DHCP message contained in the DHCP packet. If the client runs on a remote server, specify the IP address of the server. Now click the “Add…” button in the Predefined options window. If the TFTP client runs on a local server, specify the IP address 127.0.0.1.Now you will need to right click on IPv4 and choose “Set Predefined Options…” Here you will find all of the options are predefined like Router and DNS Servers, but it also lets you create new ones.Setup the scope as you normally would with all the relevant information. As I’m sure your voice guys will tell you the IP phones will need to go on their own VLAN and defined through the network, an item for another post. Next you’ll need to go ahead and create a scope for your Cisco IP telephony devices.Once you have the DHCP Server installed and authorized, launch DHCP Manager.From Server Manager choose to add a role and choose DHCP Server.

If you already have done some of these steps, please feel free to skip ahead to the parts you need. I’m going to proceed here as if you’re working with a bare server that is already a member of the domain. TFTP Server IP address L2Q1 enable Q tag L2QVLAN241 assign vlan 241 to the IP phone VLANTEST60 test the vlan for 60 seconds upon bootup. The problem is the option for TFTP server, option 150, is not built a default option on any DHCP servers that I’ve ever worked with. Description Configuring DHCP Options for Avaya IP Phones Solution 7/11/11 Description The network contains Avaya IP phones that may not have PCs. So how does the phone know where to find this TFTP server? That information is passed to the device as an option when it receives its IP address from the DHCP server, much in the same way it learns the default gateway and DNS servers. All of this is fed to the device via the transfer of a configuration file from the TFTP server integrated into Cisco Call Manager. With Cisco’s IP phone system the end phone devices are dumb devices, they store no configuration at all and have to be fed up to date firmware revisions. DHCP Options 66/67 allows an option to include an IP address of a TFTP Server (Option 66) and the name of a configuration file (Option 67) in a DHCP ACK packet.
One of the bigger systems that I find myself supporting in my infrastructure is our Unified Communications system from Cisco Systems.
