This read-write enumerated object selects which operation, reading a random entry, reading the next entry, updating, deleting, or reading a block of entries, should be performed on the address table entry identified by the accompanying index fields. An admin or management script uses this to walk through or manipulate the switch's potentially large address table efficiently, since read-next and read-block allow iterating without needing to know every address in advance. For example, a script auditing the full address table would repeatedly set kxaddrOperation to read-next(2) and read kxaddrIndex and kxaddrNext to step through every learned address one at a time.
