Cisco SG350 28P extension

[shayanjaved]

Hi, 

I have a SG350 switch with two L3 vlans along with inter vlan routing enabled. 

I want to extend the network by adding another SG350-28P switch. How can I replicate the vlans or what are my options

Stacking is not supported

Thanks

You would connected both switches via trunk. 

Example

SW1 Gi0/1 Switch mode Trunk

SW2 Gi0/1 Switch mode Trunk

You can setup the VLANs on both switches manually or use GVRP to propogate vlans between switches . Usually on catalyst switches, we use vtp but I'm not sure if that is an option the the SG series yet.
