Description

Hi,

Psense+ version: 22.01

When I try to add jumbo frames to lagg interface ( 9000 ) - main
When I change the main interface enabled with no ip address the vlans configured under the lagg instantly lose their parent device.

lagg1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
description: LAGG1

ifconfig lagg1.115|grep vlan
groups: vlan
vlan: 0 vlanpcp: 0 parent interface: <none>

How am I suppose to enable jumbo frames on a aggregated link without losing vlan device links?
Also how to keep it persistent from the gui without doing hacks during bootup.

it appears with 22.05 too.

to workaround :

re-save the Lagg interface Interfaces>LAGGs

after resaving:
lagg0.100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
options=3<RXCSUM,TXCSUM>

ifconfig lagg0.100|grep vlan
groups: vlan
vlan: 100 vlanpcp: 0 parent interface: lagg0
