A table is maintained in a memory. The table has entries which identify by which port of the multiple port network device other network devices communicate with the multiple port network device. The table is updated by monitoring packets received by the multiple port network device. When a packet is received by the multiple port network device, a port number over which port the multiple port network device received the packet is determined. Also, a source address of a network device from which the packet originated is determined. When the source address is not listed in the table, the table is updated with an entry for the source address which includes the port number. | |
