OPNsense 26.7.4 - VLAN traffic failing over X550/LAGG/bridge after upgrade

[merrins63]

I have got a question that really bugs me :

Why would you do this =>

I also have an Intel i226 2.5 GbE trunk, with corresponding VLAN interfaces bridged to the X550/LAGG VLAN interfaces.

Aren't you effectively Bridging 2x 2,5 Gbps with 2 x 10 Gbps ?!

What is the purpose of such a setup ??

The issue I'm trying to solve with this design is mainly about making the best use of the different network speeds available in my home.

I have a traditional 1 GbE wired network, which is perfectly adequate for many of my wired IoT devices. However, my wireless access points and newer switches are capable of 2.5 GbE.

I need my wired and wireless IoT devices to remain on the same VLANs and subnets, while allowing the 2.5 GbE side of the network to make use of the faster interfaces rather than forcing everything through the existing 1 GbE switching infrastructure.

I'm also planning to upgrade my Internet connection to 2000/200 in the next few months, and I already have several multi-gigabit devices that will be able to take advantage of that bandwidth.

Previously, I used the more traditional approach of a single 24-port Gigabit Ethernet switch. However, with affordable 2.5 GbE switches now readily available, I wanted to take advantage of the Cat6A cabling already installed throughout my house.

The important point is that this design isn't intended for redundancy. The objective is to utilise the available 1 GbE and 2.5 GbE links efficiently while keeping devices within their existing VLANs.

Using bridged VLAN interfaces on OPNsense allows me to achieve that design.

Hopefully that explains the reasoning behind my setup a little better.
