If it's an SNMPv3 implementation, that's a bug. The end is signalled by being returned a variable that's lexically later than the range you wanted; the SNMP agent never knows where you intended to stop. >Apart from missing items after an empty row, retrieving data this way is >very >inefficient.

Get-next should be able to get through. Perhaps you should contact the SNMPv3 group to discuss the problem. firstname.lastname@example.org - it is considered polite to join the group before asking questions, instructions can be found on the WG page.
