[SNMP4J] missing values with walk operation

[Katona Attila]

I have a problem with snmp4j when getting the 64bit counter
information from a cuda1000 cmts. The result with the linux snmpwalk:

snmpwalk -v 2c -c public 10.251.0.2 .1.3.6.1.2.1.31.1.1.1.6
IF-MIB::ifHCInOctets.8781825 = Counter64: 0
IF-MIB::ifHCInOctets.8781826 = Counter64: 0
IF-MIB::ifHCInOctets.8781827 = Counter64: 54192
IF-MIB::ifHCInOctets.8781828 = Counter64: 105430070

IF-MIB::ifHCInOctets.8781832 = Counter64: 0
IF-MIB::ifHCInOctets.8978433 = Counter64: 0
IF-MIB::ifHCInOctets.8978434 = Counter64: 0
IF-MIB::ifHCInOctets.8978435 = Counter64: 0
IF-MIB::ifHCInOctets.8978436 = Counter64: 0
IF-MIB::ifHCInOctets.1082392576 = Counter64: 0
IF-MIB::ifHCInOctets.1099169793 = Counter64: 0

The result with the snmp4j:

java -jar SNMP4J.jar -c public -v 2c -p GETBULK -Ow udp:10.251.0.2/161

Total requests sent:    1

I've tried with snmp4j-1.11.2.jar (java version: sun 1.5.0_22 os:
debian linux 5.0.8)

Please help, Thx,
