Systems and methods for hard zoning in networks

Method and system for a network device configured to control access to other devices in a network is provided. The network device includes a port configured to receive a frame. The port includes a plurality of sub-ports configured to operate as independent ports for sending and receiving frames using one of a plurality of network links at a plurality of rates and complying with a plurality of protocols. The network device also includes a source address look up table (ALUT) and a destination address look up table (LLUT), wherein when the frame is received the network device is configured to compare a source identifier of the frame and a destination identifier of the frame to the ALUT and the LLUT. When one ALUT table entry matches the source identifier of the frame, the network device outputs a bit map of zones based on the source identifier of the frame, compares the output bit map of zones with a zone bit map of the LLUT, and when there are any matching bits between the two maps, transmits the frame.
