网络工程 - 如何监控 Cisco 1941W 子接口上的流量 - 吾爱随笔录

我对路由器不是很熟悉，我的搜索目前证明有点徒劳。我的任务是为我们的路由器创建一个监视器。我使用以下 OID 来获取有关我想要监控的不同接口的相关信息

1.3.6.1.2.1.2.2.1.10
1.3.6.1.2.1.2.2.1.16
1.3.6.1.2.1.2.2.1.2

我发现您必须在 OID 的末尾添加接口索引才能获取特定接口的信息（例如1.3.6.1.2.1.2.2.1.10.2）

我此时遇到的问题是我必须监控的另一个路由器的接口在物理接口上配置了子接口。当我sh int可以在界面上看到子界面时。这是信息

我在这个论坛的 MIB 中找到了ifHCInOctets和ifHCOutOctets，但我不确定我应该如何询问这个。因为启动MIB已经比正常的ifInOctetsMIB要长了。

我必须启用 SNMP 吗FastEthernet0/0/0.20？例如，我必须使用什么 MIB 来获取InOctets信息。最后我还需要.1在1.3.6.1.2.1.31.1.1.1.6MIB的索引中添加一个。
