Hi all,

Now systemd-networkd will send DHCP release packet when BMC reboots. This may cause BMC to lose its original aquired IP after next boot up. I see this feature can be disabled by adding below lines to the configuration file of systemd-networkd:

[DHCPv4]
SendRelease=false

Does it make sense to disable DHCP release? Or is there any reason for the current default configuration in phosphor-network?

Thanks,

Heyi

FWIW, users within Intel get very cranky when their IPv4 addresses change. I'm presently working on a defect related to the IP address being altered.

As it is unclear there is a run-time mechanism for changing this value, I'd at least like to see a compile time control. I expect Intel will choose to block sending a DHCP release request for when the BMC reboots.
