设备信息:软件版本见附件截图,设备是C9800-CL 无线控制器。

问题:夜莺nightingale监控,目前使用的通用OID获取到的是committed memory。在官网找的MIB文件对应OID,通过snmpwalk验证也不对。

Standby WLC can be monitored directly only if WLCs that run in RMI + RP HA type. It is done through the standby's Redundancy Management Interface (RMI) IP address of the standby WLC.

In this scenario, only OIDs from IF-MIB are officially supported, which makes it possible only to monitor the state of all the interfaces on the standby WLC. Example output from 9800-CL WLC:

 

Standby WLC state can also be monitored with the query to the active WLC. Only CISCO-LWAPP-HA-MIB and CISCO-PROCESS-MIB MIBs are officially supported. When active WLC in HA is queried, the first response represents the value of the active WLC, while the second response represents the value of the standby WLC.

By OID 1.3.6.1.4.1.9.9.109.1.1.1.1.12 ,can get the used memory of the standby slot(which is slot 0).But how to get the used memory of active slot (slot 1)?

通过1.3.6.1.4.1.9.9.109.1.1.1.1.12和1.3.6.1.4.1.9.9.109.1.1.1.1.13查到的是slot 0的数据(应该是默认slot 0?)那么如何查询slot1的数据呢?或者slot 1的OID需要在哪个MIB .my文件里找?
