【说明】

本命令可以查看pppoe用户的详细信息。

32. 清除动态生成的vlan接口

user@MX960> clear auto-configuration interfaces xe-0/2/1

【说明】

本命令可以手动清除动态生成的VLAN接口，慎用！

33. 强制pppoe用户下线

user@MX960> clear pppoe session

【说明】

本命令可以手动清除所有pppoe用户的会话，强制用户下线重拨，慎用！

34. 强制ipoe用户下线

user@MX960> clear dhcp relay binding all

【说明】

本命令可以手动清除所有ipoe用户的dhcp relay绑定关系表，同时强制清除了用户的demux0接口。后果是用户在dhcp地址租期超期前或续租前将不能网络访问，需要用户手动ipconfig /release和renew，重新获取地址才能恢复网络接入。慎用！

40. Windows系统主机Pathping命令

提供有关在源和目标之间的中间跃点处网络滞后和网络丢失的信息。Pathping 在一段时间内将多个回响请求消息发送到源和目标之间的各个路由器，然后根据各个路由器返回的数据包计算结果。因为 pathping 显示在任何特定路由器或链接处的数据包的丢失程度，所以用户可据此确定存在网络问题的路由器或子网。

Pathping 通过识别路径上的路由器来执行与 tracert 命令相同的功能。然后，该命令在一段

指定的时间内定期将 ping 命令发送到所有的路由器，并根据每个路由器的返回数值生成统计结果。

简单来说，

ping 查看你到你想去的地方通不通；

tracert 查看你到你想去的地方该怎么走； pathping 查看你要走的这条路的路况怎么样。

pathping [-n] [-h MaximumHops] [-g HostList] [-p Period] [-q NumQueries [-w Timeout] [-i IPAddress] [-4 IPv4] [-6 IPv6][TargetName]

参数 -n

阻止 pathping 试图将中间路由器的 IP 地址解析为各自的名称。这有可能加快 pathping 的结果显示。

-h Maximum_Hops

指定搜索目标（目的）的路径中存在的跃点的最大数。默认值为 30 个跃点。 -g HostList

指定回响请求消息利用 HostList 中指定的中间目标集在 IP 数据头中使用“稀疏来源路由”选项。使用稀疏来源路由时，相邻的中间目标可以由一个或多个路由器分隔开。HostList 中的地址或名称的最大数为 9。HostList 是一系列由空格分隔的 IP 地址（用带点的十进制符号表示）。 -p Period

指定两个连续的 ping 之间的时间间隔（以毫秒为单位）。默认值为 250 毫秒（1/4 秒）。 -q Num_Queries

指定发送到路径中每个路由器的回响请求消息数。默认值为 100 个查询。 -w Timeout

指定等待每个应答的时间（以毫秒为单位）。默认值为 3000 毫秒（3 秒）。 -i IPAddress

指定源地址。 -4 IPv4

强制使用IPv4。 -6 IPv6

强制使用IPv6。 TargetName

指定目的端，它既可以是 IP 地址，也可以是主机名。 /?
