Layer 3 switch as a Gateway

Good morning 

 

I have a  single SG350 switch connected to a Modem-route. I want to disconnect the router from the switch and that all PC's communicate with each other using the switch, as they do not require Internet connectivity. I wonder if that can be done and how I come about to do it ?  Do I only need to post the gateway on the PC's to the switch or do I need to do some other additional changes on the Switch ??

 

Thanks for your answers

If all the PC belong in same subnet then just connect and no need to configure anything on switch or else if different subnet you need to do inter vlan routing.

Hi @Okami11  

 

It should be possible if you want only the PCs to communicate with each other just remember if you're not doing static IPs, you'll have to create the DHCP pool on the switch so that it can assign IPs to new PCs, if not just make sure you configure the right VLAN on the switch (layer 2 and layer 3) and configure the correct IP, subnet mask and gateway on the PCs and switch should be able to handle the routing.

 

Thanks.
