About AARP 7-11
The AARP maintains an Address Mapping Table (AMT) with the most
recently used hardware addresses and their corresponding AARP addresses.
If an address is not in this table, AARP sends a request to the protocol
address and adds the hardware address to the table when the destination
node replies. You can view this table, called the AARP cache, through the
LANplex Administration Console.
