I have a Cisco 5520 firewall that I want to VLAN connect to a WLC and 5 AP's so I can separate into a inside corporate network and a guest network that will just have access to the Internet. I need a good PoE and layer 3 switch? Any recommenations? I will be connecting the switch and firewall via Gigabit Ethernet cable as I have no fiber module on the ASA.
You can use a 3560X. Usually 3560 is cheaper then 3750X if you don't need stacking.
Have a look:
