Traffic Management Actions can enforce bandwidth restrictions and guarantee a minimum amount of bandwidth for one or more policies. Each Traffic Management Action can include settings for multiple interfaces. For example, on a Traffic Management Action used with an HTTP policy for a small organization, you can set the minimum guaranteed bandwidth of a trusted interface to 250 kbps and the maximum bandwidth to 1000 kbps. This limits the speeds at which users can download files, but makes sure that a small amount of bandwidth is always available for HTTP traffic. You can then set the minimum guaranteed bandwidth of an external interface to 150 kbps and the maximum bandwidth to 300 kbps to manage upload speeds at the same time.
Before you implement Traffic Management, you must know the available bandwidth, and decide how much bandwidth you want to guarantee or limit for different types of network traffic. For more information, see Get Started with Traffic Management.
For devices that run Fireware XTM v11.8.x and lower, all policies that use a given Traffic Management Action share its connection rate and bandwidth settings. When they are created, policies automatically belong to the default Traffic Management Action, which enforces no restrictions or reservations. If you create a Traffic Management Action to set a maximum bandwidth of 10 Mbps and apply it to an FTP and an HTTP policy, all connections handled by those policies must share 10Mbps. If you later apply the same Traffic Management Action to an SMTP policy, all three must share 10 Mbps. This also applies to connection rate limits and guaranteed minimum bandwidth. Unused guaranteed bandwidth reserved by one Traffic Management Action can be used by others.
You can now apply this Traffic Management Action to one or more policies.
