SNMP MIB可视化工具建议?

有没有MIB的免费可视化工具?我被分配了一些snmp陷阱规范化/扩展工作,并被分配给cisco ons 15454s作为开始。MIB看起来比我见过的其他的更复杂。许多对象交叉引用,包括一些到在其他mib中定义并导出的对象的交叉引用。尝试跟踪报警端口号的快速示例:

报警定义:

Cerent454AlarmEntry ::= SEQUENCE {
    cerent454AlarmIndex          INTEGER,
    cerent454AlarmObjectType     Cerent454EntityClass,
    cerent454AlarmSlotNumber     INTEGER,
    cerent454AlarmPortNumber     CerentPortNumber,
    cerent454AlarmLineNumber     INTEGER,
    cerent454AlarmObjectIndex    INTEGER,
    cerent454AlarmType           Cerent454AlarmType,
    cerent454AlarmState          CerentNotificationClass,
    cerent454AlarmTimeStamp      TimeStamp,
    cerent454AlarmObjectName     DisplayString,
    cerent454AlarmAdditionalInfo DisplayString
}

来自同一文件(cerent-454.mib)的cerentportnumber引用:

IMPORTS
    (...)
    CerentPortNumber
        FROM CERENT-TC

(...)
cerent454AlarmPortNumber OBJECT-TYPE
    SYNTAX      CerentPortNumber
    ACCESS      read-only
    STATUS      mandatory
    DESCRIPTION 
        "This will indicate what is the port
         of the object which raised this alarm."
    ::= { cerent454AlarmEntry 40 }

cerentportnumber的实际语法,来自cerent-tc.mib:

CerentPortNumber ::=
      INTEGER
      {        unknown   (1),
               port0     (5),
               port1    (10),
               port2    (20),
               (...)
               port62  (620),
               port63  (630),
               port64  (640),
               portAll (10240)
             }

也许这并不像感觉的那么复杂,但这只是一个小例子。感觉应该有一个基于gui的“explorer”类型的应用程序,它可以让我很容易地看到这些引用,而无需在文件和文件中的位置之间来回切换。有什么建议吗?
