摘要： A transmit portion of a network device including a medium access control (MAC) module configured to receive a frame of data to be transmitted from the network device in accordance with a MAC security (MACsec) protocol. In response to the frame of data being a precise time protocol (PTP) frame, the MAC module is configured to encrypt the PTP frame in accordance with the MACsec protocol, and associate an identifier with the encrypted PTP frame. A physical layer module includes a transmit module configured to transmit the encrypted PTP frame from the network device at a particular time. A PTP module configured to, based on the identifier associated with the encrypted PTP frame, generate a time stamp indicating the particular time that the transmit module transmits the encrypted PTP frame from the network device. The time stamp is transmitted from the network device along with the encrypted PTP frame.

摘要： A network apparatus including a central processing unit, first physical layer devices, a second physical layer device, and a network switch. The network switch includes first ports communicating with the first physical layer devices; a second port communicating with the second physical layer device; and third and fourth ports communicating with the central processing unit over first and second media independent interfaces, respectively. The network switch includes a switch core module configured to route data packets between connected ports, including the first and third ports. The network switch includes a bypass switch configured to (i) in response to a first mode being selected, directly connect the second port and the fourth port, bypassing the switch core module, and (ii) in response to a second mode being selected, disconnect the second port from the fourth port and connect the second and fourth ports to the switch core module.
