When I do a snmpwalk from the zabbix server, I always get an answer:

[root ~]# snmpwalk -v2c -c public 192.168.30.47 .1.3.6.1.4.1.14685.3.1.132.1.10.6
SNMPv2-SMI::enterprises.14685.3.1.132.1.10.6 = Counter64: 489706383560

Don't know why some items are supported on one check, then get unsupported for the next 5 checks ?

What could I do to debug and see exactly what zabbix is trying to do because with snmpwalk, it's always good.

Try to disable bulk requests

Thanks DmitryL , you're my hero, I've lost so much time on this and disabling the bulk request solve my issue :-)

Thanks a lot!

[DmitryL]

Just don't think that bulk requests is a bad thing Simply some devices don't support it
