How to get and set OID value in custom SNMP MIB

I am very new to SNMP and I need to get "system uptime" using our own enterprise OID.

I have already obtained an IANA number and created a MIB file.

The problem is when I use snmpget command with our OID, I get an object not found error at the command prompt.

Although when I do a snmptranslate on our object, I get the exact OID of that object.

If any additional information is required from my side, please let me know.

When you use snmpget, an SNMP request is made via IP to an SNMP agent on a remote (or local) host to return a specific piece of data. A MIB is used to describe in human readable terms, what that data is and where to find it. On the other hand, snmptranslate is a tool used to parse a given MIB. It parses a local MIB file, and doesn't make any contact with an agent.

Since you mentioned creating a new MIB, I assume your trying to add new functionality to an SNMP agent. To do this, the agent must be extended. If you're using Net-SNMP, there are a few options including compiling new source code into the agent, using a sub-agent, and using external scripts via pass and pass-persist protocol.
