上面是标量对象的样例MIB文件。poolUsage是单个OID的存储...我想把它添加为一个表，这样我就可以赋值，比如poolUsage.1，poolUsage.2等等。我想把这个标量转换成一个“表”格式...我应该做哪些更改？请帮帮我。

Answer 1

如果你需要写任何复杂的东西，我强烈建议你买一本关于MIB的书。这是一种“有趣的”语言，如果你在写东西的时候掌握好它会更好……

但是，您至少应该阅读描述该语言的RFC2578 (不过，它比教程更正式)。您可能还会看到一个示例，比如RFC2863: the IF-MIB，它包含一个简单的表(ifTable)，其中包含一个可以复制的结构。

参见this tutorial。我想这正是你所需要的。

它的要点如下：

batteryTable OBJECT-TYPE
    SYNTAX     SEQUENCE OF BatteryEntry
    MAX-ACCESS not-accessible
    STATUS     current
    DESCRIPTION
        "The (conceptual) table of batteries contained by the
        module."
    ::= { monitor 1 }

batteryEntry OBJECT-TYPE
    SYNTAX     BatteryEntry
    MAX-ACCESS not-accessible
    STATUS     current
    DESCRIPTION
        "A (conceptual) entry for one battery contained by
        the module.  The batteryIndex in the index represents
        the entry in the batteryTable that corresponds to the
        batteryEntry.

        As an example of how objects in this table are named,
        an instance of the batteryVoltage object might be
        named batteryVoltage.3"
    INDEX { batteryIndex }
    ::= { batteryTable 1 }

batteryIndex OBJECT-TYPE
    SYNTAX      DeviceIndex
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
            "A unique value, greater than zero, for each battery. 
            It is recommended that values are assigned contiguously
            starting from 1."
    ::= { batteryEntry 1 }

batteryVoltage    OBJECT-TYPE 
   SYNTAX Integer32 
   ACCESS read-only 
   STATUS current 
   DESCRIPTION 
      "Voltage A/D value" 
   ::= { batteryEntry 2 }
