Hi Mr. Yoon, Do we apply this requirement in this box model ? |
|
|
Yes, SKB asked us yesterday. So if you have any question about this, please let us know. I will ask SKB. |
|
|
After this option 225 got from DHCP lease, What is the next action from kernel? For example, set a property or something else? |
|
|
I recevied more detail information from SKB. I attached it. |
|
|
DHCP option 225 is already modified in git branch, this modification will be built in next release. |
|
|
Hi Gary, Just verified it with v15.502.9. The result on the option type 225 is OK. But there seems to be an another issue, which is that decoding for the option type 60(DHCP version information) is not correct. Please find the attached e-mail for more details. |
|
|
We will set DHCP option 60 vendor class identifier as "android-dhcp-9" in next release image. |
|
|
Hi Gary, Just verified it with v15.502.9(build 04/03), and both the option type 60 and option type 225 are OK. I will close this case if there would be no issue on the official image(v15.502.10). |

|
Hi Gary, Just verified it with v15.502.10, the test result is OK. We will close it. |

When SW upgrade (Online upgrade and FTP upgrade), DHCP does not apply private 255. |
