Create Link Usage Profile elements

Also, the Link Usage Profile elements can be used to enable the packet duplication functionality for Multi-Link tunnels.

The link usage exceptions in the Link Usage Profile element override the link selection options in QoS Class elements. If you do not specify an exception for a particular QoS class, the connection is selected according to the link selection options in the QoS Class element.

For each link type, you can add QoS Class elements to one of the following categories:

• Prefer — The specified traffic uses the link type unless a connection with significantly higher quality is available.

  For VPN connections, links that are preferred on both ends of the connection are preferred over those that are preferred on just one end of the connection.

• Avoid — The specified traffic uses link type only if necessary.
• Do Not Use — The specified traffic must not use the link.

When you select a Link Usage Profile element in the properties of an Engine, the settings defined in the Link Usage Profile element are applied to outbound traffic that uses outbound Multi-Link.

When you select a Link Usage Profile element in the properties of a policy-based VPN, route-based VPN tunnel group, or VPN broker domain, the defined settings are applied to all tunnels in the VPN according to their link types.
