Converting LAN em1 to LAGG em1 em2
I currently have em1 configured as the LAN which is used as a trunk to join 15 VLANs from pfSense to my core switch.
Since I am using pfSense as a router on a stick, I was thinking that it would be a good idea to bond em1 & em2 for extra bandwidth.
My question is: How can I do that without destroying all the VLANs? (Or am I going to have to start all over again.)
Create a new LAGG with only em2. Create VLAN tags on that LAGG. Then reassign all interfaces to the new VLANs on the LAGG.
Once nothing is assigned that uses em1, delete the VLAN tags from em1 and then add em1 to the LAGG.
You'll probably have to adjust the switch at various points along the way if it isn't smart enough to know when the port should/should not be used in the LAGG/LACP group.
