I have an answer to my question

...
    <Data "std_traffic">
        Type "if_octets"
        Table true
        Instance "IF-MIB::ifName"
        Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
    </Data>
    <Data "std_traffic64">
        Type "if_octets"
        Table true
        Instance "IF-MIB::ifName"
        Values "IF-MIB::ifHCInOctets" "IF-MIB::ifHCOutOctets"
    </Data>

    <Host "cat5.skif.local">
        Address "10.10.100.5"
        Version 2
        Community "comunity"
        Collect "std_traffic64"
        Interval 300
    </Host>
...

IF-MIB::ifHCInOctets and IF-MIB::ifHCOutOctets is 64bit counter, I think 
developers may include this in example config.

Thank you all.
