Q:

VLAN forwarding in cisco

We have a Cisco 3750X (L3) as a core switch and 10 Cisco SG-300 (L2), each Switch is in a separate VLAN (include core switch) now I want to define VLAN forwarding rule on my core switch, so all clients can see servers, how can I do it?
**3750X license:**

A:

You must enable routing with the ip routing global command.
It is only a layer-3 switch if routing is enabled. You are actually using it as a layer-2 switch.
