Abstract

A network switch which includes a 'point-to-point' to Ethernet adapter, which provides a received data frame with a media access control destination address before the received data frame is forwarded by a forwarding engine. When the frame includes IP address data, the adapter employs the IP address to obtain the media access control destination address. When the frame includes IPX address data, the adapter determines the media access control destination address as an IPX destination address or a predetermined address according as a network number in said IPX address data identifies a local network or not.
