    SNMP strange behaviour on apc device

    Hello

    I try to create a template (should become public available if it works) for the apc automatic transfer switch 4421 and frace a very strange behaviour of that snmp interface that I've never seen bevor:


    I can make a snmp walk through the outputs table for getting the voltage, frequency and ouput power of that output table:

    snmpwalk -c public -v2c 192.168.0.230 .1.3.6.1.4.1.318.1.1.8.5.4.3
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.1.1.1.1, Type=Integer, Value=1
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.2.1.1.1, Type=Integer, Value=1
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.3.1.1.1, Type=Integer, Value=221
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.4.1.1.1, Type=Integer, Value=36
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.5.1.1.1, Type=Integer, Value=-1
    OID=.1.3.6.1.4.1.318.1.1.8.5.4.3.1.6.1.1.1, Type=Integer, Value=-1

    By which the one with the value 221 represents the output power.
    But when I try to get this value directly via zabbix agent or simply snmpget, it returns variable unknown or no such instance currently exists:

    snmpget -c public -v2c 192.168.0.230 .1.3.6.1.4.1.318.1.1.8.5.4.3.1.3.1.1.1
    iso.3.6.1.4.1.318.1.1.8.5.4.3.1.3.1.1.1 = No Such Instance currently exists at this OID

    Its the same oid which snmp walk returned. Im about to get crazy.
    Am I here completely wrong (since I try for hours, even with wireshark) but cannot see the problem, or has the snmp stack of that apc device serious bugs?
