Scenario: I would like to be able to have a static block of ports and a dhcp block of ports on the same SG300 switch.
ISP - Business Cable
Cable Modem supplied by ISP has 1 Wan Port.
Static block of 8 usable IP addresses
Connected directly to this modem, I have unlimited DHCP addresses (the ISP acts as the DHCP server)
As a test, I currently have an auto sensing switch connected directly to the Wan Port on the Modem. From the auto sensing switch, I have a cable connected to the SG300-28 that is configured for the static. I also have 2 cables connected from the auto sensing switch to laptops, both of which have public dhcp addresses directly from the ISP. All of my devices on the SG300-28 as well as the laptops are connected without issue.
Is there a way that I can assign 8 ports to the static block, and then use the DHCP from the isp for the other ports? I would like to remove the auto sensing switch from this equation and configure the SG300 to connect directly to the Cable Modem.
I believe I need to make the SG300 a Layer 3 switch and configure VLANs in some way.
