Hello,
There is no support for VLANs on l2 switches in IMUNES (ng_bridge
doesn't support it, to be precise). There is ng_vlan
on FreeBSD which might be of use (I am not exactly sure if it can do what you need) but there are no plans to experiment with it just yet.

Understood, thanks for the response. You can close this if you want.

Sorry for chiming in late... Actually, we have a patch to ng_bridge bit-rotting in a private branch, which provides certain VLAN manipulation capabilities. I'd have to dig up additional docs to recall what exactly have we implemented, it was like a decade ago...
Keith: could you provide an example what exactly you'd like to be able accomplish, like receive a packet on link A tagged with VLAN X, and forward it on link B tagged as VLAN Y, while forwarding it on link C untagged? Or did you have more advanced configs in mind?

We typically use the following functionality:
- Assign native port VLAN
- Set port as either Trunk or Edge port
- Use forbidden ports to limit the VLANs transmitted over a Trunk port
When a packet arrives without a VLAN tag, it is tagged with the switch port's native VLAN prior to traversing the switch using the ports' native VLAN and trunk ports with forbidden ports settings.
When a packet arrives with a VLAN tag, the packet traverses the switch using the ports' native VLAN and trunk ports with forbidden ports settings.
Does that help? Let me know if I was unclear about anything or you need more information.
