Create a New Traffic Shaping Policy
Use the Add Traffic Shaping (QoS) Policy page to quickly configure a new traffic shaping policy.
The Add Traffic Shaping (QoS) Policy page allows you to manually enter details to create a traffic shaping policy.
1. Go to Device Configuration > System > Profiles > Traffic Shaping and click Add.
2. Enter Traffic Shaping Policy details.
Name
Enter a name to identify the Policy.
Policy Association
Select an option to specify for whom the policy is to be created.
Available Options:
* Users - Restricts the bandwidth for a particular user.
* Rules - Restricts the bandwidth of any entry to which Security Policies is applied.
* Web Categories - Restricts the bandwidth for the URL categorized under the Web category.
* Applications - Restricts the bandwidth for the applications categorized under the Application category.
Policy Type
Select the type of policy.
Available Options:
* Limit - In this type of policy, user cannot exceed the defined bandwidth limit.
* Guarantee- In this type of policy, user is allocated the guaranteed amount of bandwidth and can draw bandwidth up to the defined Limit, if available.
It enables to assign fixed minimum and maximum amounts of bandwidth to the users. By borrowing excess bandwidth when available, users are able to burst above guaranteed minimum limits, up to the defined Limit. Guaranteed rates also assure minimum bandwidth to critical users to receive constant levels of bandwidth during peak and non-peak traffic periods.
Guarantee represents the minimum guaranteed bandwidth and Limit represents the maximum bandwidth that the user can use, if available.
Limit Upload/Download Separately
Select from the available options.
Available Options:
Disable - Limits total (Upload + Download) bandwidth.
Enable - Limits Upload and Download bandwidth separately.
Priority
Set the bandwidth priority. Priority can be set from 0 (highest) to 7 (lowest) depending on the traffic required to be shaped.
* 0 - Real Time for example, VOIP
* 1 - Business Critical
* 2 to 5 - Normal
* 6 - Bulky - FTP
* 7 - Best Effort for Example, P2P
By default, priority is given to the real time traffic. However, if administrator does not want this preference, feature can be disabled from System > System Services > Traffic Shaping Settings page.
If Optimize for Real-Time (VoIP), under System > System Services > Traffic Shaping Settings page is disabled then priority will be applicable only for excess bandwidth i.e. bandwidth remaining after guaranteed bandwidth allocation.
If Optimize for Real-Time (VoIP), under System > System Services > Traffic Shaping Settings page is enabled then Real-time traffic (Traffic Shaping policy with priority 0) like VOIP will be given precedence over all other traffic.
As priority is given to the real time traffic, it is possible that some non real-time traffic will not get their minimum guaranteed bandwidth. Specifically, if sum of Limit (max allowed) of all Traffic Shaping policies (real-time and non real-time) is greater than total max-limit then guaranteed bandwidth of the real-time policies will be fulfilled but non real-time might not get the minimum guaranteed bandwidth.
Limit (in KBps) (Only if Policy Type is 'Limit' and Limit Upload/Download Separately is disabled)
Specify allowed total bandwidth.

Specify upload bandwidth.
Total Bandwidth Range: 2 – 2560000KBps
Download Bandwidth (in KBps) (Only if Policy Type is 'Limit' and Limit Upload/Download Separately is enabled)
Specify download bandwidth.
Total Bandwidth Range: 2 - 2560000KBps
Guarantee -Limit (in KBps) (Only if Policy Type is 'Guarantee' and Limit Upload/Download Separately is disabled)
Specify range for guaranteed bandwidth limit.
Total Bandwidth Range: 2 – 2560000KBps
Guarantee - Limit Upload (in KBps) (Only if Policy Type is 'Guarantee' and Limit Upload/Download Separately is enabled)
Specify range for guaranteed upload bandwidth.
Total Bandwidth Range: 2 – 2560000KBps
Guarantee - Limit Download (in KBps) (Only if Policy Type is 'Guarantee' and Limit Upload/Download Separately is enabled)
Specify range for guaranteed download bandwidth.
Total Bandwidth Range: 2 - 2560000KBps
Bandwidth Usage Type
Select the type of bandwidth usage.
Available Options:
* Individual - Allocated bandwidth is for the particular User/Rule/Web Category/Application only.
* Shared - Allocated bandwidth is shared among all the Users/Rules/Web Categories/Applications who have been assigned this policy.
