Using simple queue to limit bandwidth on an interface, And user is complaining that they can only receive total bandwidth in one direction at a time. this is the config.

When doing a transfer currently using almost 10mb upload for an hour.. they were unable to pull more than 3 megs down at the same time. (is there something wrong in the config I'm using?)

admin@MikroTik] /queue simple> print
Flags: X - disabled, I - invalid, D - dynamic
0 name="Cust1" target-addresses="" interface=ether2 parent=none
packet-marks="" direction=both priority=8
queue=default-small/default-small limit-at=12M/12M max-limit=12M/12M
burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s
total-queue=default-small


Question the whats difference between "Max-limit" and "Limit-at" options?

Hi sir
to have simple queue working in a deterministic way as expected, please define both properties target-addresses and interface.

Doing so you will observe a queue behaviour as expected.

As reported by wiki http://wiki.mikrotik.com/wiki/Manual:Queue:

Be careful to configure both of these options for the same queue - in case they will point to opposite directions queue will not work.

If neither value of target-addresses nor of interface is specified, the queue will not be able to make difference between upload and download, and will limit all traffic twice.
