Abstract
An integrated circuit includes ingress ethernet ports and egress ethernet ports. A second ingress ethernet port is configurable to operate in a selected one of a command mode and a data mode. The ingress ethernet port does not power up in the command mode and can only be put into the command mode as a result of a port modeset command being received onto an ingress ethernet port operating in the command mode. A first ingress ethernet port powers up in the command mode. In the command mode the first ingress ethernet port can receive and carry out a port modeset command. Receiving and carrying out of the port modeset command causes one of the ingress ethernet ports identified by the port modeset command to operate in the command mode. A flow table structure adapted to store flow entries is used to determine which egress ethernet port outputs a packet.
