We have learn from the previous part, how to use a Mikrotik Router by configuring basically. Today, we will learn about a popular feature of Mikrotik Router. The reason, the Mikrotik Router is used at the highest volume is because of its Bandwidth Control Function.

In the last part, circulated by the ISP of the WAN (ether1) side with Real IP, Gateway IP, DNS server IP and by configuring with a Private IP block (192.168.1.0/24) of LAN (ether5), we have learnt to use IP’s 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5, 192.168.1.6 in our personal network. Today, we will learn to control the Bandwidth of those IP’s.

However, we have to accurate the clock of the Mikrotik Router first. For this, login to Mikrotik Router by winbox.

Then, click to System>Clock and correct Date, Time and Manual Time Zone here. Click to Apply>OK.

Later, click to Queues. Click to + (add) from Simple Queue Tab here. Then, look to the following fields:
part2img1
Name: The name of that PC (according to you)

Target Address: The IP Address of that PC. (the IP to be Bandwidth controlled)

Target Upload and Target Download: The upload and download speed of that IP.
You can post the custom value willingly here, but should type lower case “k” (k = kilo bit, K = kilo byte).

Actually, the Bandwidth of the user will depend in this setting. If you set download to 256k, then the user can download at the maximum speed of 32KB.

Burst Limit (optional): If you think the user will get some more Bandwidth at the start, then how much is it? You can mention it here.

Burst Threshold (optional): How lowest the Burst Bandwidth will be is determined here.

Burst Time (optional): The value of the longevity (in seconds) of Burst Bandwidth from the start of the use. Like: If 15 minutes, then 15*60 = 900.

Time (optional): If you think, the original Bandwidth (256k/256k) will subsist for a particular time and then mention it in 24 hour format. To be mentioned, if you create Time slot for any IP, like: 00.00.00-07.59.59, then create another 02 queues for this IP and mention the remaining timeslots there. Like: 08.00.00-15.59.59 and 16.00.00-23.59.59, otherwise, problem might arise regarding Bandwidth loop.

Days (optional): Mention here, in which days you would use your Bandwidth settings.

Click to the Advance tab beside for more options.

Parent (optional): You can make Bandwidth group if you wish and can say whether this queue belongs to any group or not. Like: You can create 03 parent queues for Commercial, Marketing and Technical department of your office and also can create other queues within that queue. To create any queue, you can select it from the parent (Commercial, Marketing, Technical).

To be mentioned, the bandwidth limit of a Child queue can never cross the one of a Parent queue. If, Bandwidth limit of a Commercial queue is 512k/512k, then its Child queues will never get a Bandwidth limit more than 512k/512k.

Priority (optional): By default, the Bandwidth Priority of this IP is 8. If you think that, this IP needs maximum Bandwidth limit, then set Priority1. Example: Let, the total Bandwidth of your office is 1Mbps. Now, you have set 256k/256k in 15 PC’s. In this case, no one will get Bandwidth of 256Kbos at a time. So, if you think that 01 or more queue will get their Bandwidth available anytime (whether other queues are facing Bandwidth crisis), then set priority1 for those queues.

Finally, click to Apply>OK. One queue will be created then. Alike, create queues for all your IP’s. Remember, the IP’s for which queues are not made and Bandwidth control were not set but are used in your network, will receive unlimited Bandwidth. The same will happen if you disable (x) any of the queues.

Apart from the options mentioned above, you can control Bandwidth by setting Name, Target Address, Upload and download limit only. The rest of the options are for Advanced level use. We will see the use of these options in another function next.
