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.
