    使用snmptuil.exe 可以查看代理的 MiB对象,下列文本框内oid部分是( ).C:\ Users\Administrator> snmptuil get 192.168.1.31 public.1.3.6.1.2.1.1.3.0Variable=system.sysUpTime.0Value=TimeTicks 1268830

    A.192.168.1.31
    B.1.3.6.1.2.1.1.3.0
    C.system.sysUpTime.0
    D.TimeTicks 1268803

    答案:B
    解析:
    C:\>snmputil get 192.168.1.31 public .1.3.6.1.2.1.1.3.0public .1.3.6.1.2.1.1.3.0是指的系统开机时间多长。OID(对象标识符),是SNMP代理提供的具有唯一标识的键值。MIB(管理信息基)提供数字化OID到可读文本的映射。所有完全验证OID都有 .iso.org.dod.internet.private 开始,数字表达为: .1.3.6.4. 。几乎所有的OID都会跟上企业(.1)和由IANA(互联网编号分配中心分配的)唯一的厂商标号。 OID的相对格式,从企业值开始,略过所有的隐含地址。因此,可以用相对地址 enterprises.netapp.netappl.raid.diskSUmmary.diskSpaceCount.0 来表示上述的OID,或者用数字格式 .1.789.6.4.8.0 .某些唯一键值,可用多个实例表示,这样所有的OID都以实例值结尾。因此可以看到大多数OID都是以一个 .0 结尾的。
