许鹏鹏,某局点12508G-AF无法通过snmp读取oid节点
问题描述
现场通过SNMP读取设备信息，发现无法获取，PC和设备之间ping正常，看PC上最后显示是如下信息，另外看debug信息比较少，但是有回显，且有response
PC显示：
SNMPv2-SMI::entERPrises.232.18.1.3.0 = No more variables left in this MIB View (It is past the end of the MIB tree)
过程分析
1、检查配置，没有什么问题
snmp-agent
snmp-agent community read public
snmp-agent sys-info version v2c
snmp-agent target-host trap address udp-domain 1.1.1.1 params securityname test1 v2c
undo snmp-agent trap enable configuration
undo snmp-agent trap enable l3vpn
undo snmp-agent trap enable mac-address
undo snmp-agent trap enable system
2、display snmp-agent mib-view显示为空，没有任何输出，正常情况默认是有回显的，回显如下，因此判断客户误删了mib-view相关配置，需重新添加下。
[DR2]dis snmp-agent mib-view
View name: ViewDefault
MIB Subtree: iso
Subtree mask:
Storage-type: nonVolatile
View Type: included
View status: active
View name: ViewDefault
MIB Subtree: snmpUsmMIB
Subtree mask:
Storage-type: nonVolatile
View Type: excluded
View status: active
View name: ViewDefault
MIB Subtree: snmpVacmMIB
Subtree mask:
Storage-type: nonVolatile
View Type: excluded
View status: active
View name: ViewDefault
MIB Subtree: snmpModules.18
Subtree mask:
Storage-type: nonVolatile
View Type: excluded
View status: active解决方法
重新添加误删除的配置后解决
添加snmp-agent mib-view include ViewDefault iso
snmp-agent mib-view exclude ViewDefault snmpUsmMIB
snmp-agent mib-view exclude ViewDefault snmpVacmMIB
snmp-agent mib-view exclude ViewDefault snmpModules.18
