I have to set up our network in our new office. I'm no networking expert (developer), but I need some input and advice here for some things I wonder about.
I have purchased the following:
- 2 x Cisco CS200 smart-switch 24p
- 1 x VoIP PBX (VoIP + 4 access points)
- 1 x dual LAN router
- 4 x 2.4 GHz Wi-Fi access points (Wi-F1 1)
- 2 x 5 GHz access points (Wi-Fi 2)
Connected like this:
- Switch 1 (link port) is connected to the router
- Switch 2 (link port) is connected to Switch 1 (standard port)
- PBX/access points and Wi-Fi are all connected to the switches
My questions are about the networking itself:
Am I killing the speed connecting SW1->SW2 through a regular port? Should I get a SFP cable, or does that not matter for this size of network?
Would it be smarter to connect SW2 directly to the router instead of to SW1?
The other questions I have are about (probably) VLANs:
I would like to isolate the PBX/VoIP part, and prioritize traffic from this. The Cisco switches have some options for this, I think, but would this be smart to set a VLAN to those only, or is it overkill? Any directions to how I can do this? The most important thing is that the phone system gets highest priority on the network, and I don't want/need the people to be able to access it.
I would like Wi-Fi 1 to be the primary network (a VLAN for this too?). Wi-Fi 2 is thought of as an extra fast network for our developers, with very few limitations, but I would like this network to be able to see the primary network (Wi-Fi 1), but I don't want Wi-Fi 1 to be able to see Wi-Fi 2. Can this be done?
The last question is very basic about VLANs. Am I correct in the understanding that the VLAN has to flow from the router? As the switches are not layer-3, so the router has to control the VLAN, right?
