Compatible Switch with CM1100

I am looking to buy the CM1100 Cable modem and it has 2 ethernet ports that can be channel bonded. I would like to add a swtich where all my ethernet wires are located and connect the switch to the CM1100 ethernet port. THe manual says not to connect an unmanaged switch to the port so is there a list of ethernet switches I can connect to it? Do I need a non-blocking or a fully managed switch? Thanks!
