Step 1: Enable Bandwidth Management on WAN interface
1. Navigate to the Network | Interfaces page. 2. Click on the Configure button under an interface in the WAN zone (In this example the X1 interface). 3. Click on the Advanced tab and do one or both of the following:
Under Bandwidth Management, to manage outbound bandwidth, select the Enable Egress Bandwidth Management checkbox, and set the Available Interface Egress Bandwidth (Kbps) ( Upload Speed )field to the maximum for the interface.
Under Bandwidth Management, to manage inbound bandwidth, select the Enable Ingress Bandwidth Management checkbox and set the Available Interface Ingress Bandwidth (Kbps) ( Download Speed )field to the maximum for the interface.
4. Click on OK to save.
Once BWM has been enabled on an interface, and a link speed defined, traffic traversing that link will be throttled—both inbound and outbound—to the declared values, even if no Access Rules or App Rules are configured with BWM settings.
Egress and Ingress BWM can be enabled jointly or separately configured on WAN interfaces. Different bandwidth values may be entered for outbound and inbound bandwidth to support asymmetric links. Link rates up to 100,000 Kbps (100Mbit) may be declared on Fast Ethernet interfaces, while Gigabit Ethernet interfaces will support link rates up to 1,000,000 Kbps (Gigabit). The speed declared should reflect the actual bandwidth available for the link. Oversubscribing the link (i.e. declaring a value greater than the available bandwidth) is not recommended.
