POAP via DHCP

[Eric Marquez]

I'm planning to use PoAP via DHCP, does anybody know the settings that are needed for the DHCP server.  I'm planning to use Windows 2012R2.

Hi,

The process and required DHCP options are documented in the DHCP Discovery Phase section in the Using Power On Auto Provisioning configuration guide.

From the above:

"POAP requires a minimum DHCP lease period of 3600 seconds (1 hour). POAP checks the DHCP lease period. If the DHCP lease period is set to less than 3600 seconds (1 hour), POAP does not complete DHCP negotiation.

The DHCP discover message also mandates some of the options and solicits these options from the DHCP server after receiving the DHCP OFFER from the DHCP server.

• Option 66 ( TFTP server name) or Option 150 (TFTP server address) - The DHCP server relays the TFTP server name or TFTP server address to the DHCP client. The DHCP client uses this information to contact the TFTP server to obtain the script file.
• IP address
• Default gateway
• Option 67 (Bootfile name) - The DHCP server relays the bootfile name to the DHCP client. The bootfile name includes the complete path to the bootfile on the TFTP server. The DHCP client uses this information to download the script file."
