Define a Traffic Management Action in v11.8.x and Lower
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.
Traffic Management Actions in Fireware OS v11.8.x
For devices that run Fireware OS 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 10 Mbps. 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.
Configure OS Compatibility
Because Traffic Management functions differently for different versions of Fireware OS, you must configure the OS Compatibility setting before you can add a Traffic Management action. If the OS Compatibility setting is unknown, Policy Manager automatically opens the OS Compatibility dialog box the first time you add a Traffic Management action. For more information about OS compatibility, see Configure Fireware OS Compatibility.
Create or Modify a Traffic Management Action
To create or modify a Traffic Management Action, from Fireware Web UI:
- Select Firewall > Traffic Management.
The Traffic Management page appears.
- Select the Enable Traffic Management check box to enable Traffic Management.
- Click Add to create a new Traffic Management Action.
Or, select an action and click Configure.
- Type a Name and a Description (optional) for the action. You use the action name to refer to the action when you assign it to a policy.
- Click Add.
- From the Interface drop-down list, select an interface.
- In the Minimum text box, type or select the minimum bandwidth for that interface.
- In the Maximum text box, type or select the maximum bandwidth for that interface.
- Click OK.
- Repeat Steps 4–7 to add traffic limits for additional interfaces.
- To remove an interface from the Traffic Management Action, select it and click Remove.
- Click Save.
You can now apply this Traffic Management Action to one or more policies.
To create or modify a Traffic Management action, from Policy Manager:
- Double-click the policy for which you want to guarantee a minimum bandwidth. Select the Advanced tab. Click .
Or, select Setup > Actions > Traffic Management and click Add.
The New Traffic Management Action Configuration dialog box appears.
- In the Bandwidth configuration for outgoing traffic section, click Add.
An interface drop-down list appears.
- In the Interface column, click the drop-down list to select the interface for which you want to set a minimum bandwidth.
If you select an External interface, the action applies to upload speeds.
If you select a Trusted or Optional interface, the action applies to download speeds.
- Double-click in the Minimum guaranteed bandwidth and Maximum bandwidth columns to edit the settings. Type a number to set the minimum or maximum bandwidth in kilobits per second.
- Click OK.
- If you defined the traffic action from a policy definition, the new traffic action now appears in Traffic Management on the Advanced tab.
If you defined the traffic actions from Setup > Actions > Traffic Management, you must Add a Traffic Management Action to a Policy for it to have an effect on your network.
