RouterOS Scripting

Then we create quueue tree, and change Max upload and download speed under DSL_IN and DSL_OUT (global-in
gloabal-out) and chanege priority rules to suit your needs:

/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=
10000000 max-limit=11000000 name=DSL_IN packet-mark=“” parent=global-in
priority=1 queue=default
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0
max-limit=0 name=100bao_p2p_in packet-mark=100bao_p2p_in parent=DSL_IN
priority=8 queue=default
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \

here i have some doubt parent=global-in (what is this global-in)
DSL_IN and DSL_OUT IS THE NAME OF THE QUEUES IF I AM NOT WRONG

Please help in trouble


Thanks in advance
