Bandwidth Allocation per LAN Port

I have a hAP ac and would like to know how limit download and upload bandwidth by LAN Port only (not by class or priority or anithing like that)?

For example:

LAN2: unlimited
LAN3: limited to 30.0 Mbps down and 3.0 Mbps up
LAN4: limited to 5.0 Mbps down and 0.5 Mbps up

Any guidance would be greatly appreciated.

Thank you in advance!

Add a simple queue with the “target” as the interface name, do this for each interface you’d like to add bandwidth limitations to.

Can you show me with some screenshots?
It would be a great help!

Login via winbox, on the left, click “Queues”

You should get the “Queue List” window:

Click the “+” button to add a queue:

You’ll now get the “New Simple Queue” window:

Where is says “target”, select the interface that you want to apply the bandwidth limitation to from the drop down, on the “Target upload” and “Target download” entries, put in the values that you want. Once you have done that, on the top, click the “Advanced” tab:

On the “Limit At” “Target upload” and “Target download” entries, put in the same values that you specified in the previous tab and then click “Ok” on the right top of the window.

Do this for all the interfaces that you’d like to apply limitations to.
