This read-write INTEGER reports, and can be set to, the next index value to use for a subsequent read-next or read-block operation on the address table, and is initialized to -1 when the ELS-100 boots. An admin's script uses the value returned in kxaddrNext after each read-next operation to know exactly what index to use for the following one, allowing sequential traversal of the full address table. For example, after reading one address table entry via read-next, a script would copy the returned kxaddrNext value into kxaddrIndex before issuing the next read-next request to continue walking the table.
