Want to implement VLANs as our network has grown. We have a Sonicwall Pro 3060 that is supported by a third party. In order to have control over most of the network would like to install another Sonicwall, setup 3 VLANs and have the new Sonicwall feed traffic to the existing Sonicwall. Do not want to have to go to through the third party vendor every time we want to make a change to the network.
In addition to the Sonicwall we have 2 Dell 5524 switches, an HP switch that is also VLAN capable and several unmanaged switches.
First question - Since I'm new to VLANs do we have to eliminate all non-VLAN switches in order to setup properly? I'm pretty sure the answer is yes.
Second question - What do you think of the network design with 2 Sonicwall's? I know I can do it with a layer 3 switch, but I'm more familiar with the Sonicwalls.
Final question - Can you mix and match different switches as long as they are VLAN capable?
Thanks for your replies!
