As said above switchport set the port to be layer 2, you assign a vlan to it and then need an SVI to configure L3 for ip connnectivity. If you do no switchport the port is layer 3 and you place an IP address directly on the port. I am guessing you want a static default route between the switch and the firewall. Dont forget you need routes in the firewall pointing back to the subnets you have configured in the switch


switchport means the interface is in layer 2 mode, forwarding frames as a switch. no switchport means the interface is in layer 3 mode, routing packets.
