SNMP MIB SMIv2一致性组问题

Question

我有一个MIB,我开始研究,但smilint抱怨缺少一致性组.如何将此一致性组添加到我的文件中？

BLEH-PRODUCT-MIB DEFINITIONS ::= BEGIN

产量smilint:

$ smilint ./BLEH-PRODUCT-MIB

它只是意味着您应该在MIB文档中定义OBJECT-TYPE实体之前定义OBJECT-GROUP实体.

以RFC 1907为例,

http://tools.ietf.org/html/rfc1907

snmpGroup OBJECT-GROUP
    OBJECTS { snmpInPkts,
              snmpInBadVersions,
              snmpInASNParseErrs,
              snmpSilentDrops,
              snmpProxyDrops,
              snmpEnableAuthenTraps }
    STATUS  current
    DESCRIPTION
            "A collection of objects providing basic instrumentation and
            control of an SNMPv2 entity."
    ::= { snmpMIBGroups 8 }

首先定义,然后定义

snmpInPkts OBJECT-TYPE
    SYNTAX     Counter32
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
            "The total number of messages delivered to the SNMP entity
            from the transport service."
    ::= { snmp 1 }

关于组的重要性,您可以阅读RFC 2580.

http://tools.ietf.org/html/rfc2580

由于您要定义组,因此建议添加关联的MODULE-COMPLIANCE.
