Use unused LAN ports as switch ports for networking possible

Hi all,
I have got a question about unused nics on a proxmox server, i don't use the server as a firewall/router (eg PFsense) because that is handeled by my fibre Fritz box and im happy with that.
My Proxmox server is running on a Topton Intel 13th gen 8505 mini pc with 8x Intel I226-V nics and i'm only using 1 port so the other 7 are doing nothing.
Is it possible to make those 7x 2,5Gbe nics act as just simple switch ports that connect to the rest of my network?
If yes, i can re-use my 5 port 2,5Gbe switch that is standing next to the Proxmox server for something else and save some power.
Ant help is appreciated.
Cheers!
 
You can bridge multiple NICs to vmbr0 to do that. But I don't think it will save power. 7 additional busy general purpose NICs should consume way more power than a dumb 5-port switch.

Hi Dumuin,
Thanks for the reply, i will defo give that a try and measure the power consumption.
I can repurpose the switch on the first floor where there is a older 8x1Gbe/2x10Gbe switch thats kinda power hungry.
Cheers!

Hi,
I have bridged all other nics to vmbr0 (see below picture) Schermafbeelding 2023-11-16 170015.pngbut when i plug devices in the other nics they do not get an ip while one of these nics is connected to my switch and so router wich is the DHCP.
Is this the right way to use the other 7 ports as extra switchports that have acces to the same network that the proxmox server is running on?
Rgds,
Martijn
