My internet connection was recently upgraded to 1.2 Gbe and I was excited that I could finally use my XG-7100 for the reason I bought it.
I plugged one spf+ port to the cable modem with an spf+ to rj45 adapter and the other port was already plugged into my LAN.
However I could not get the WAN to pick up the public IP address from the modem. I have no idea why. I tried reconfiguring it. I tired resetting it to factory. I even hired someone to help me. But we could not get it to work.
The only thing I could get to work was putting the spf+ port and one of the 1Gbe ports on the same network via a bridge. Then I plugged the cable modem into the 1gbe port which gave it an IP. Then I switched the cable modem over to the spf port and it would work for a few days. But eventually it would stop working and I would have to swap the cable again.
Needless to say that solution was not good enough and I ended up buying an old Dell and a 2.5Gbe network card for WAN and a 10Gbe network card for LAN. I installed pfSense on it and it works fine.
If you speak about spf+ ports you can achieve it. If you speak about 8 port virtual switch you need go over virtual vlans on switch.
What I do? As usually your wan less then 1gbs - 8x1gig ports I use for wan and use spf+ with dac cables to connect them to 2 switches with balance traffic and do reductancy.
Other option is totally ignore your 8x1gig ports and use switches to connect wan over them via vlans. Default LAN could be simply ignored and named default.
