DHCP Pool not showing leases for VLANs

DHCP isn’t showing my leases for my VLANs when I use “show dhcp server leases” or “show dhcp server leases pool Users”

It is working just fine for leases not using a VLAN.

Make sure the vlan has an IP address in that space (bit by that one myself).

If you have not already, tcpdump the VIF and make sure it sees BOOTPC datagrams to rule out any inside switch/vlan issues.

If all that is good, you can try sending a HUP to the running kea-dhcpv4, restart with systemd or reboot. Apparently, there is an issue where kea-dhcpv4 does not always pick up new VIFs and it seems others have filed bug reports on it.
