   DESCRIPTION  "A simple mib for demonstration purposes.
                "
   ::= { netSnmpExamples 4 }

-- Define typical mib nodes, like where the objects are going to lie. -- we'll prefix everything in this mib with nst (net snmp tutorial) nstMIBObjects OBJECT IDENTIFIER ::= { netSnmpTutorialMIB 1 } nstMIBConformance OBJECT IDENTIFIER ::= { netSnmpTutorialMIB 2 }

-- define 3 objects, which will all be implemented in different ways -- within the tutorial.

nstAgentModules OBJECT IDENTIFIER ::= { nstMIBObjects 1 }

nstAgentModuleObject OBJECT-TYPE

   SYNTAX      Integer32
   MAX-ACCESS  read-write
   STATUS      current
   DESCRIPTION

"This is an object that simply supports a writable integer when compiled into the agent. See http://www.net-snmp.org/tutorial-5/toolkit/XXX for further implementation details."

   DEFVAL { 1 }
   ::= { nstAgentModules 1 }

nstAgentSubagentObject OBJECT-TYPE

   SYNTAX      Integer32
   MAX-ACCESS  read-write
   STATUS      current
   DESCRIPTION

"This is an object that simply supports a writable integer when attached to the agent. The object should be accessible when the agentx subagent containing this object is attached. See http://www.net-snmp.org/tutorial-5/toolkit/XXX for further implementation details."

   DEFVAL { 2 }
   ::= { nstAgentModules 2 }

nstAgentPluginObject OBJECT-TYPE

   SYNTAX      Integer32
   MAX-ACCESS  read-write
   STATUS      current
   DESCRIPTION

"This is an object that simply supports a writable integer when attached to the agent. This object should be accessible when the dynamic plugin has been loaded into the agent. See http://www.net-snmp.org/tutorial-5/toolkit/XXX for further implementation details."

   DEFVAL { 3 }
   ::= { nstAgentModules 3 }

-- -- The above definitions produce a section of the mib tree that looks -- like this (including our parent node, printed using the -- snmptranslate command): -- -- -- % snmptranslate -M+. -mNET-SNMP-TUTORIAL-MIB -Tp -IR netSnmpTutorialMIB -- +-netSnmpTutorialMIB(4) -- | -- +-nstMIBObjects(1) -- | | -- | +-nstAgentModules(1) -- | | -- | +- -RW- Integer32 nstAgentModuleObject(1) -- | +- -RW- Integer32 nstAgentSubagentObject(2) -- | +- -RW- Integer32 nstAgentPluginObject(3) -- | -- +-nstMIBConformance(2)

-- You can then use the snmptranslate command to get the numerical or -- textual OID representation of any piece of the tree:

-- Getting a OID: --  % snmptranslate -M+. -mNET-SNMP-TUTORIAL-MIB -IR nstSSSecondsSinceChanged -- .1.3.6.1.4.1.2021.13.4242.1.1.2

-- Getting a textual OID: --  % snmptranslate -On -M+. -mNET-SNMP-TUTORIAL-MIB -IR nstSSSecondsSinceChanged -- enterprises.ucdavis.ucdExperimental.netSnmpTutorialMIB.nstMIBObjects.nstScalarSet.nstSSSecondsSinceChanged

-- Getting a description: --  % snmptranslate -Td -M+. -mNET-SNMP-TUTORIAL-MIB -IR nstSSSecondsSinceChanged -- .1.3.6.1.4.1.2021.13.4242.1.1.2 -- SYNTAX TimeTicks -- UNITS "1/100th Seconds" -- MAX-ACCESS read-only -- STATUS current -- DESCRIPTION "This object indicates the number of 1/100th seconds since the -- nstSSSimpleString object has changed. If it is has never been -- modified, it will be the time passed since the start of the -- agent."
