如果本地测试ok，远程测试出现如下报错：
No Such Object available on this agent at this OID或No more variables left in this MIB View (It is past the end of the MIB tree)
修改snmpd.conf(/etc/snmp/snmpd.conf),并重启snmpd（service snmpd restart)
access notConfigGroup "" any noauth exact systemview none none -->
access notConfigGroup "" any noauth exact all none none
在snmpd.conf配置文件里面，查找以下字段：[/color]
## incl/excl subtree mask
#view all included .1 80
将该行前面的"#"去掉.
之后重启snmpd服务解决。
