Mikrotik uses to specify rate limits:

rx-rate[/tx-rate] [rx-burst-rate[/tx-burst-rate] [rx-burst-threshold[/tx-burst-threshold] [rx-burst-time[/tx-burst-time] [priority] [rx-rate-min[/tx-rate-min]]]]

From Mikrotik’s LAN interface, when a router receives data client is uploading (rx). When router transfers data, means client is downloading (tx). Hence, rx-rate/tx-rate means upload/download respectively.

If both burst threshold upload (rx-burst-threshold) and burst threshold download (tx-burst-threshold) are not specified but burst upload/burst download is specified, upload (rx-rate) and download (tx-rate) is used as burst thresholds.

If the download (tx-rate) is not specified, it is counted the same as upload (rx-rate). The same goes for burst download (tx-burst-rate), burst threshold download (tx-burst-threshold), and burst time download (tx-burst-time)

If min upload (rx-rate-min) and min download (tx-rate-min) are not specified, upload (rx-rate) and download (tx-rate) values are used. The min upload (rx-rate-min) and min download (tx-rate-min) values can not exceed upload(rx-rate) and download(tx-rate) values.

If both burst time upload (rx-burst-time) and burst time download (tx-burst-time) are not specified, 1 second is used by default.

Priority takes a value between 1 and 8 where 1 is the highest priority and 8 is the lowest.
