我说的踢人就是断开PPPOE用户，比如ERX系列可以这样操作：
查看用户：
erx#sh subscribers ?
&> Display and redirect the output to a file, replacing previous
contents
&>> Display and redirect the output to a file, appending to
previous contents
> Redirect the output to a file, replacing previous contents
>> Redirect the output to a file, appending to previous contents
domain Display subscribers based upon domain name
ipv6 Display subscribers' ipv6 information
port Display subscribers based upon port
summary Display subscriber summary
username Display subscribers based upon username
virtual-router Display subscribers based upon virtual-router context
| Filter output using the CLI Filtering feature
<cr>
断开用户：
erx#logo su ?
all Logout all PPP subscribers
domain Logout PPP subscribers based upon domain
port Logout PPP subscribers based upon port
username Logout PPP subscribers based upon username
virtual-router Logout PPP subscribers based upon virtual-router context
