[xiaoshuai.zhu@devops-centos7-shanghai-area0 ~]# snmpwalk -c public -v 1 172.16.0.1 sysObjectID     # 获取OID
[xiaoshuai.zhu@devops-centos7-shanghai-area0 ~]# SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.25506.1.332    # 获取到的信息
[xiaoshuai.zhu@devops-centos7-shanghai-area0 ~]# snmptranslate -On -IR SNMPv2-SMI::enterprises.25506.1.332  #OID 转换
.1.3.6.1.4.1.25506.1.332   #翻译后的OID
