Abstract
A layer management interface (LMI) to communicate with a processor over MDIO protocol, and to communicate with a media access control security (MACsec) functional block over a local network protocol, the LMI including a command register to receive command information for transacting data information with the destination portion within the MACsec, an address register to receive address information associated with the destination portion without conducting all the MDIO address cycles required by the MDIO protocol to receive the address information, the LMI being configured to determine a location of the destination portion based on the received address information, and a data register to transact the data information without conducting all MDIO data cycles required by the MDIO protocol to transact the data information, and to transact the data information with the determined destination portion based on the command information over the local network protocol.
