So I have an Aruba 2530 switch with a couple of SFP slots, an incoming fiber connection and a modem that only has RJ45. There's limited space and I want to use as little boxes as possible.
Is there some way that I could use an SFP in the switch, send that to the router and then have the rest of the ports be interconnected and used internally on the LAN? Like making a separate trunk? I haven't dealt with exactly this variant before and it would be interesting to know the answer.
The incoming connection should have a VLAN 101 and 102 which has to be preserved in order to get IPTV to function correctly, and has an upstream DHCP server. The router uses pfSense.
Sorry in advance for the MSpaint sketch, I didn't have anything else on this computer.
