Problem with monitoring PDUs via SNMPv3

[DIAnanev]

Good day everyone!
Found interest moment with monitoring PDUs Chatsworth. If I asked two same devices using snmpwalk I got two absolutely different OID. Look on the picture!
If you anyone knows, how it will be fixed I will be appreciate

That looks like a bug in Chatsworth's SNMP implementation. If you look at the "OID", everything starting at the 48.48.48 is just the decimal ASCII representation of what appears to be the MAC address that is being returned. The last 4 numbers in the fake "OID" are different only because the last 4 characters of the MAC address are different.
