Router – SNMP agent on embedded device, No such object available on this agent at this OID

docsislinuxroutersnmp

SNMP agent on an embedded device. When I query SNMP device for the particular private enterprise OID object, it says "No such object available on this agent at this OID".

snmpget -v2c -c public 10.x.x.x .1.3.6.1.4.1.8595..

These objects are included in MTA config file. So my assumption was that these private OIDs objects are present in the system, but they may not be available for viewing with default "public" community string, or they are shown via SNMP version v3c access, or some more reasons. So first I should check SNMP agent code built into that device, does it actually contain that private MIBs? If it contains, then it should be accessible via SNMP query, is it correct? Or even it exist on the SNMP agent, it may not be accessible with SNMP query?

Whenever I face issues with an OID not being found, I always use the snmpwalk command, in order to see what the devices do respond to:

snmpwalk -v 2c -c public 10.x.x.x
