SG200-50 VLAN Intercommunication

[Dan Lalonde]

Hello

Given SG200-50 don't have CLI, how can I create VLAN but make sure they're able to connect together?

I have a Cisco router already connected to the switch. Is is necessary for the VLAN to talk to each other? Can the switch do that on its own? Do I need another router to do it?

Thanks! :)

Hi Dan, the SG200 switch is a layer 2 device. This means if you'd like the VLAN to communicate to one another a router or layer 3 device would have to do this for you. By nature, VLANS do not talk to each other. A routing device must accomplish that for you.

Thank you for your reply. The fact that the switch is already connected to a router should do the trick then?

Dan, this will work if your router supports 802.1q sub interface or if it supports trunk and VLAN tag.

I understand. Thank you. Thanks to your post I discovered that my router is indeed not what I need for multiple VLANs.

I will have to buy another router.
