For control the bandwidth usage, the router offers the default limit of general regulation, the limitation list for IP-based policies, Smart Bandwidth Limit to apply only to the client using a large number of sessions. This article also explains the priority between them, the Auto Adjustment option for more flexibility, and using Time Schedule to turn on/off Bandwidth Limit.
To add Bandwidth Limit rules, go to Bandwidth Management >> Bandwidth Limit. There are three major parts in Bandwidth Limit: Default Limit (Overall Regulation), Limitation List and Smart Bandwidth Limit. To use any of them, remember to enable Bandwidth Limit first.
It's the general regulation. Input value here to set a limit for all the LAN clients. Note: "0" means unlimited. Therefore, if you want to enable Bandwidth Limit, but only want to use the Limitation List, you should enter "0" here.
For example, the configuration below will limit all the client's bandwidth usage to 2000 Kbps upload and 8000 Kbps download.
Network Administrator can add the bandwidth policy for the specific LAN client here. Selecting "Each" to give each IP the entered bandwidth, or "Shared" to give a total bandwidth for a group of LAN clients.
For example, the configuration below has two rules. Index 1, each of the six IPs from 192.168.1.10 to 192.168.1.15 has 100 Kbps for download and upload. Index 2, the 6 IPs from 192.168.1.20 to 192.168.1.25, will share 1000 Kbps download and upload together.
"Smart Bandwidth Limit" is used to apply bandwidth limit to only the client whose session number has exceeded the defined value (probably using Peer-to-peer file sharing), while the others can have the bandwidth specified in the default limit.
For example, the setting below will regulate a transmission limit down to 200kbps for upload and 800kbps download to the LAN client who uses more than 1000 sessions.
Specific Limitation has the highest priority. And among the limitation in the list, the one with the smallest index number has the highest prioity. Next will be Smart Bandwidth Limit if selected. The last will be the Default Limit.
To better use the bandwidth you subscribed, enable Allow auto adjustment… of available bandwidth to allow the clients to obtain more bandwidth when the total bandwidth is still sufficient.
You can apply bandwidth limit only during the peak hours.
1. To set a schedule for the bandwidth limit, click "Schedule Profile."
2. Select an index available.
3. Edit the schedule profile as follows,
4. Go back to Bandwidth Management >> Bandwidth Limit, scroll down to the Time Schedule part. Fill in the index of schedule profile. Then, click OK to save the settings, then only during the time specified in the schedule profile, will the Bandwidth Limit be applied.
Go to Diagnostics >> Data Flow Monitor, check Enable Data Flow Monitor, and it will show the current upload/download rate of each IP, and their limitations.
Note: The "+" symbol behind the rate number means Auto Adjustment is in use, users are allowed to use more bandwidth than the limit if the total bandwidth is still sufficient.
1. Go to Bandwidth Management >> Bandwidth Limit and click "Add" to start the configuration.
2. Set up the new rule as follows,
3. Bandwidth Limit can also be used with a schedule to restrict LAN clients' bandwidth usage only at a particular time. In the profile:
4. Furthermore, you may enable Default TX/RX Limit to apply restrictions the other unspecified LAN clients.
5. We can also enable Smart Bandwidth Limit to restrict the bandwidth of unspecified LAN clients only when their session number is over the threshold.
To check the bandwidth usage of each client, go to Diagnostics >> Data Flow Monitor and enable the monitor then we can check the transmission rate.
