Description

Tested on 22.01 and 21.05. Issue can be reproduced on ESXi with pass-through NIC, and on an 1100; unable to reproduce on 5100.

After bouncing the interface then checking Status / Interfaces:

  1. ifconfig igb0 down: interface down; DHCP down
  2. ifconfig igb0 up: interface up; DHCP down (no interface IPs shown)

While in this state, DHCP seems to have run given that ifconfig shows the interface has addresses, packets flow correctly, and gateway status shows online.

This is the correct behavior - if you manually execute ifconfig eth0 up, it will not restart DHCPd using the services_dhcpd_configure() function.
This is true for most types of interfaces, with the exception of static IP.
