We currently have 1 switch on our network, it is a L2, Dell Powerconnect 3548P. We have 2 VLANs setup, and our Sonicwall Gateway/ Router does all the inter-vlan routing.
We utilize 1 VLAN for DATA and 1 VLAN for VOICE. Currently we get some "jitter" in the calls, i think due to the sonicwall having to route all the VLAN traffic and getting overwhelmed.
We are out of spots on our 3548P, and need to add another switch. Would the best route be to add a Dell Powerconnect 6224P L3 switch, which would allow all the inter-VLAN traffic to be routed at the switch level, and just allow the sonicwall to act as the external gateway?
Will the 3548P, and 6224P work together in a stack configuration, or do they have to be like models?
What other caveats would there be to a setup as such?
