配置RMON示例

操作步骤

1. 配置路由器和网管站路由可达（略）
2. 配置允许向网管站发送Trap

   # 使能SNMP发送Trap的功能。

   <HUAWEI> system-view

   [~HUAWEI] sysname Device

   [*HUAWEI] commit

   [~Device] snmp-agent

   [*Device] snmp-agent trap enable

   # 配置向指定的网管站发送Trap。

   [*Device] snmp-agent target-host trap address udp-domain 10.1.1.1 params securityname public

   [*Device] commit

3. 配置统计功能

   # 使能RMON统计功能。

   [~Device] interface gigabitethernet 0/3/0

   [~Device-GigabitEthernet0/3/0] rmon-statistics enable

   [*Device-GigabitEthernet0/3/0] commit

   # 配置以太网统计功能。

   [~Device-GigabitEthernet0/3/0] rmon statistics 1 owner userA

   [*Device-GigabitEthernet0/3/0] commit

   # 配置历史采样功能，对子网中的流量信息采样，采样间隔为30秒钟，并保存最近10次数据。

   [~Device-GigabitEthernet0/3/0] rmon history 1 buckets 10 interval 30 owner userA

   [*Device-GigabitEthernet0/3/0] commit

   [~Device-GigabitEthernet0/3/0] quit

4. 配置告警功能

   # 配置RMON的1号事件向网管站发送Trap消息。

   [~Device] rmon event 1 description alarmofinterface trap public owner userA

   [*Device] commit

   # 配置告警阈值功能，设置采样间隔和触发告警事件1的阈值。

   [~Device] rmon alarm 1 1.3.6.1.2.1.2.2.1.4.3 5 absolute rising-threshold 1000 1 falling-threshold 100 1 owner userA

   [*Device] commit

   [~Device] quit

5. 检测配置结果

   # 查看子网的数据流量信息。

   <Device> display rmon statistics gigabitethernet 0/3/0
