Hi,

DHCP4_LEASE_ADVERT is usually a good sign. Log shows that an address has been 
allocated.

What do you mean by allocation not occuring or accruing? Does the perfdhcp 
report the packet as dropped? Does the packet reach perfdhcp's interface if you 
do a capture?

Moreover, how is this VLAN set up? Are both VLAN interfaces on the same 
machine? Why do you need to use VLANs if the VLAN-free setup works?

hi All

I’m using perfdhcp to test my kea-DHCP, while trying to produce DHCP requests 
via VLAN interfaces, the address allocation process doesn't end successfully.in 
the DHCP log I see all sessions end with "DHCP4_LEASE_ADVERT" message and no 
allocation accurse.

while using perfdhcp without VLAN the allocation accrues successfully.

while using the VLAN interface with a single DHCP client (netplan not prefdhcp) 
allocation to the VLAN interface is successful.

so it seems like when using the VLAN interface with prefdhcp the client doesn't 
claim the offered address.

basically, I'm a bit lost here, so if someone has any idea what is happing 
here, it will be awesome.

i hope I'm just missing an option in my perfdhcp command and not a limitation.

attached debug log of the fail transaction.

Thanks
