Abstract
An Ethernet switch has at least one ingress/egress portwhich is operable in two modes, in a first mode as a GE port and in a second mode as a plurality of FE ports. The port has 8 MAC interfaceseach of which is capable of receiving/transmitting FE packets, and at least one of the MAC interfaces can be configured to receive/transmit GE packets. Thus, the port has two modes of operation. The port further includes receive and transmit moduleswhich receive GE and FE packets from, and transmit GE and FE packets to, the interfaces. If there are 8 such ports in the Ethernet switch, then by switching different numbers of the ports between the two modes, the switch may operate in 9 different modes: as 8 GE ports, 7 GE ports and 8 FE ports, 2 GE ports and 48 FE ports, 1 GE port and 56 FE ports, or simply as 64 FE ports.
