Vlan on lagg doesnt# work

[traxanos]

we have have 4 network cards. we have group it by lagg mit mode fail over (later lacp). on lagg0 we have create different vlans. the clans interfaces are down, because parent interface are <none>.

lagg0_vlan504: flags=8803 <up,broadcast,simplex,multicast>metric 0 mtu 1500
	options=103 <rxcsum,txcsum,tso4>ether 00:00:00:00:00:00

I've seen lagg+vlan working on numerous customer configs on 2.0.x and 2.1.

What is the date on the 2.1 image you're running?

Did you just configure the VLANs?

Do they stay broken even after a reboot?

This does not seem good

status: no carrier

[traxanos]

at the moment it works. i didn't know if the update to the latest build does fix or the reboot of both firewalls.

it is possible that the problem exists if we change something on lagg and you need every time a reboot after such changes?

I've never seen that required for lagg in general. Unless it's a problem specific to the failover mode, it's not likely a general issue.
At least with LACP, which is the most common, it usually just works without any fuss.
