Data Volume Limit allows the administrator to assign a limit on the amount of data that passes through each SSID per month. This feature is aimed mainly at limiting download/upload on a Guest Wifi network, but it can be applied to all SSID's.
Apply Data Volume Limit to a wireless network (SSID).
Navigate to Management > Configuration > Wireless > Advanced > Data Volume Limit. Select the check box to enable Data Volume Limit and configure the following settings accordingly:
Monthly limit: set a value for the limit in MB. The default is 1024MB, maximum is 100TB. When the limit is reached no more data can pass through the SSID.
Data limit control by: Apply the limit to download, upload or both.
Reset data limit counters at: Set the time and day of the month when the limit resets.
Reset counter: Click the Reset Counter button to reset the counters immediately.
Applying to SSID Profiles.
By default the No Data Volume Limit check box is selected on all SSID's meaning the data volume limit is not applied to any SSID.
To enable the Data Volume Limit on an SSID, clear the No Data Volume Limit check box for the SSID. Do this for each SSID to which you wish to apply the data volume limit.
Profile Data Volume Limit (%): Drag the slider to assign a percentage of the overall monthly limit to each SSID.
- To make sure that each SSID receives its exact share of the total monthly data volume limit, make sure that the percentages for all SSIDs together do not exceed 100 percent.
- To set a less restrictive policy, the percentages for all SSIDs together do not need to add up to 100 percent. For example, if you set 60 percent for one SSID and 60 percent for another SSID, you are providing equal chance to each SSID to consume 60 percent of the total monthly data volume limit. If one SSID actually consumes 60 percent, only 40 percent is available for the other SSID.
- If you do not set a data volume limit for any SSIDs, all SSIDs are allowed 100 percent of the total monthly data volume.
Per Client: If you set a percentage for an SSID, set a monthly data volume limit that applies to each WiFi client of the SSID by entering the monthly data volume limit in MB per WiFi client. Take the total monthly data volume limit and the percentage that you set for SSID into account. For example, if the total monthly data volume limit is 500000 MB, the percentage for the SSID is 60 percent, and you expect about 30 clients to connect to the SSID, you could set a data volume of 10000 MB (10 GB) per WiFi client of the SSID.
When the remaining data volume reaches 10 percent of the monthly data volume limit for a WiFi client, the data rate for that WiFi client is restricted to 256 Kbps. The WiFi client is not notified when they hit this limit.
Data Volume Limit Policy on SSID Profile
Pop up a warning message: percentage of MB before the limit is reached. The administrator will receive a pop up message in the access point web gui.
When SSID profile limit is reached: When the monthly limit is reached, choose whether to drop all data or disconnect all wireless clients from the SSID.
