Abstract
Methods, systems, and computer program products for selective layer 2 port blocking using layer 2 source addresses are disclosed. According to one method, a layer 2 frame is received. An I/O port block list is identified based on a layer 2 source address in the layer 2 frame. A set of ports to which the layer 2 fame should be forwarded is identified. The frame is blocked from being forwarded to ports in the set that are also in the I/O port block list.
