A network device includes a port coupled to a device, another port coupled to another device, and an access control list with an access control entry that causes the network device to permit log in frames to be forwarded from the first device to the second device. The network device receives a frame addressed to the second device and determines the frame type. If the frame type is a log in frame, then the frame is forwarded to the second device and another access control entry is added to the access control list. The second access control entry causes the network device to permit data frames to be forwarded from the first device to the second device. If not, then the frame is dropped based upon the first access control entry.
