我在ros中使用的脚本（经过测试可行）

节省磁盘资源
:foreach i in=[/system logging facility find local=memory ] do=[/system logging facility set $i local=none]

限速脚本
:for aaa from=2 to=254 do={/queue simple add name=("ip_" . $aaa) dst-address=("192.168.176.". $aaa)  max-limit=128000/400000 interface=wan burst-limit=500000/1500000 burst-threshold=128000/512000 burst-time=30s/1m time=7h0m0s-18h0m0s,mon,tue,wed,thu,fri disabled=no}

限线程脚本
:for aaa from 2 to 254 do={/ip firewall filter add chain=forward src-address=(192.168.176. . $aaa) protocol=tcp connection-limit=50,32 action=drop}

node_off
:for aaa from 2 to 254 do={/queue sim dis [find name=("ip_" . $aaa)]}

node_on
:for aaa from 2 to 254 do={/queue sim en [find name=("ip_" . $aaa)]}
