Re: Failed to clear configuration in Ip4Config2 Protocol

["Wu, Jiaxin" <jiaxin.wu@intel.com>]

Hi karunakar,

You can verify the DNS device path with HTTP boot feature. After the successful HTTP boot DNS parsing,  the device path should be like: //....../Mac(...)[/Vlan(...)][/Wi-Fi(...)]/IPv4(...)[/Dns(...)]/Uri(...).

That is recommend way for the verification.

Besides, you can also draft the App to call  the DevPathFromTextDns and DevPathToTextDns libraries for the more verification.

Thanks,
Jiaxin
