Edgerouter/Edgeswitch: SFP as trunk port

What is the proper way to use the SFP ports as trunk port for VLans used on the switch ports of the router (ER-12) as well as on the switch (ES-8-150W and ES-10X), but without create a brdige on the router between the switchports and the SFP ports?
thank you for showing me the right direction to go.
Thank you in advance.

I don’t have an ER-12 handy. Can you post pics of the interfaces screen and then on Switch interfaces click configure, and then submit screenshots of the VLANs tab on that configure screen.

Hello Willie

Here are the requested screen shots. Thank you for your help.

As long as the SFP interface is in that Switch0 config you’re golden.

I found this note very early in my search for a solution.

" Your ER-12 isn’t going to allow you to use ports above 7 in the same layer 2 network (broadcast domain) as the the lower ports 0-7 are part of the switch, the upper 4 ports are dedicated interfaces directly connected to the CPU. What that means to your use-case: The only way to allow any of the upper 4 ports to “participate” in the layer 2 switching network is to use the software bridge device, and you don’t want to do that; it is a performance killer. "

So I believe I have to do something like this?
ER-12 eth10/eth11 are the SFP ports.
give eth10 a IP in the MGMT Network 99, like say 192.168.99.253/28.
add each needed VLan to eth10 as done on the switch0.
eth11 will be the WAN port.

ES-8-150W eth9/eth10 are the SFP ports
give them a IP in the MGMT Network 99, like say 192.168.99.250/28 and 192.168.99.249/28

ES-10X eth11 is the SFP port
give a IP in the MGMT Network 99, like say 192.168.99.247/28

What i do not know is if I also have to do the routing stuff (Static or OSFP) on those SFP ports as well and if YES, then how is this done.

Hello thotha,

Were you able to get this figured out and working to allow the same VLANs that are used for any of the ports 1-7 (as switch0) also on the SFP port (i.e. eth10)?

I’m needing to get my ER12 reconfigured with one of its SFP ports as a trunk.

Hoping you did get this working and can share the details.

Thanks in advance!
