Some background: I currently have:
- Switch A Main 48 port 1Gbps (DLink)
- Switch B 10Gbps Backbackbone (DLink)
- Switch C 24 port 1Gbps (DLink)
Telephone Switch 1-24 port phone switch connected to a 3rd-party supplier's switch.
My setup is as follows:
PC's --- Switch A ----- Switch B (and servers) ----- Switch C --- PC's
I have PCs connected to Switch A. These connect to those on Switch C via Switch B where the servers are also connected
I want to plug the phone system into Switch A, and then be able to plug a telephone into a port on Switch C and get VOIP.
I've set up a small test on a single switch using the following VLan's
1 - default
20 - Data
50 - Voice
Which worked perfectly. I had both networks plugged in and all seemed to be happy.
So the questions ...
- Do I need to configure the VLANs on all switches or just those with a phone / PC connected?
- Do the backbone connections need to be tagged in a VLAN or will leaving it in the default be enough?
I also have a number of other switches that are connected to Switch A. These are data-only and do not need telephone access. Am I correct in assuming that simply tagging the ports as data only will be sufficient?
Thanks
