    And this is right.

    When i created Zabbix Item with snmp walk with same OID i've got that:

    Code:
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.0 = Gauge32: 12
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.1 = Gauge32: 14
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.2 = Gauge32: 14
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.3 = Gauge32: 10
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.4 = Gauge32: 13
    .1.3.6.1.4.1.9.9.449.1.4.1.1.5.65536.103.5 = Gauge32: 10
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.0 = STRING: "24w6d"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.1 = STRING: "17w6d"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.2 = STRING: "6y2w"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.3 = STRING: "6y2w"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.4 = STRING: "14w5d"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.5 = STRING: "20w4d"
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.0 = Gauge32: 25
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.1 = Gauge32: 1
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.2 = Gauge32: 1
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.3 = Gauge32: 1
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.4 = Gauge32: 12
    .1.3.6.1.4.1.9.9.449.1.4.1.1.7.65536.103.5 = Gauge32: 1​
    And that isnt rigth.
    Feeling that zabbix ignored some subtrees. .65536.40 and got only .65536.103.

    is it bug or feature?
    PS Zabbix 7.0.12

    hey boyarskij,

    just for troubleshooting purposes, if you configure a zabbix item with the specific sub .40 OID, do you get data?

    Kind regards

      It is a good question! Definitely no!
      But Why?
      at the same time, via linux console and snmpwalk is OK.

        Sure those are sme devices? Data for same OID-s, is so different, that I have questions about it ..
        Code:
        iso.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.0 = STRING: "6d02h"
        iso.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.1 = STRING: "24w5d"
        vs
        Code:
        .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.0 = STRING: "24w6d"
        .1.3.6.1.4.1.9.9.449.1.4.1.1.6.65536.103.1 = STRING: "17w6d"
