I purchased Opnsense and now have a problem with the ax0 interface. If, for example, the firewall restarts due to a power outage, etc., I don't receive any traffic over the VLANs. I then have to restart the firewall again via the web interface.
Versions
OPNsense 25.4.1-amd64

Please provide way more details about how your firewall is configured, VLANs and IP addresses, parent interface, what kind of connection to the switch, hardware offloading enabled or disabled, untagged interface used in addition to VLANs or not, ...
Everything.
Nobody here has got a working crystall ball. My ax0 and ax1 interfaces with LACP and VLANs are all working fine. There is something wrong with your particular configuration and to find the cause we need ... well ... the configuration.
I have made some screenshots.
The other vlans are same then the Vlan2.
The switch Model is the Cisco 9300. The SFP Modul is the FlexOptix. Later there will be the SFP+ Model from FlexOptix.
On the Cisco there is the interface configured as trunk. No native Vlan.
