ABSTRACT:
A LAN switching system includes an Address Match Control line which can be set (activated) and is monitored by each port adapter card. If a port adapter card recognizes an address on the switch fabric, the adapter card copies the frame with the address and activates the Address match Control line. The set Address Match Control line causes the remaining port adapter cards to stop searching for a match. If the Address Match Control line is not set, the frame can be copied by all port adapters which are configured to do so.
