I have a SonicWall firewall configured with 3 vlans on virtual interfaces on one physical interface. I have a wireless access point configured with 3 wireless networks configured to each of the three vlans. That is all working well.

I purchased a cisco SG300 switch with the purpose of having an ethernet connection to one of the vlans. I'm having trouble getting this to work and could use some pointers.

I think that I need to configure one of the ports to automatically tag any traffic passing through it with correct VLAN tag. Is this the right understanding?

Yes that is true. You need to configure your interface on SG300 to pass through the vlan network. Here is what you can do.

1> Log onto to the SG300, either console or ssh

a> show interface status { verify if the interface you connected is up }

b> Create a vlan.

c> Configure the interface in switchport mode with above vlan updated to the access list.
