SG 300-28 how to prevent inter VLAN routing

[Heinz Deubler]

I have a SG 300-28 switch with the latest firmware installed running in Layer 3 mode.

I configured this router with 4 VLAN's where VLAN 1 is connected to the network router. All VLAN's call all communitcate with one another. How do I go about configuring VLAN's so that they can only communicate with the router and the internet and not each other?

Hi Heinz, that being the case, you should use the switch in layer 2  mode. There is no benefit to use this product in layer 3 if you do not  wish to have it locally route between vlans unless you have a router  that does not understand vlans or sub interfaces and requires static  routes to make other vlans use the internet.

If you want, you may use the command set

configure terminal

no ip routing

You will be able to ping the switch vlan interfaces but you will not ping past those interfaces.
