cacti监控添加节点总显示状态为Unknown是怎么回事
cacti中添加节点后一直显示状态为unknown，服务端本机状态可以监控，但监控远程的机器时就出现这种情况，服务端未对snmpd.conf配置作改动，被监控服务器的snmpd.conf配置文件如下：
# sec.namesource community
com2sec notConfigUserdefault public
com2sec notConfigUser127.0.0.1 public
com2sec notConfigUser192.168.7.41public #192.168.7.41为服务端的IP，被监控端机器IP为192.168.2.40
其它配置都是按默认来的
在服务端执行snmpwalk -v 1 192.168.2.40 -c public显示如下：

这种情况该作何处理，是因为跨网段引起的么？ 解决了，之前一直想着把unknown解决了再创建视图的，后来网上查了下，再创建视图后重建缓存视图就可以，配置没问题
