 ** Action **   <a name="networkmanager-Type-ServiceInsertionAction-Action"></a>
The action the service insertion takes for traffic. `send-via` sends east-west traffic between attachments. `send-to` sends north-south traffic to the security appliance, and then from that to either the Internet or to an on-premesis location.   
Type: String  
Valid Values: `send-via | send-to`   
Required: No

 ** Mode **   <a name="networkmanager-Type-ServiceInsertionAction-Mode"></a>
Describes the mode packets take for the `send-via` action. This is not used when the action is `send-to`. `dual-hop` packets traverse attachments in both the source to the destination core network edges. This mode requires that an inspection attachment must be present in all Regions of the service insertion-enabled segments. For `single-hop`, packets traverse a single intermediate inserted attachment. You can use `EdgeOverride` to specify a specific edge to use.   
Type: String  
Valid Values: `dual-hop | single-hop`   
Required: No

 ** Via **   <a name="networkmanager-Type-ServiceInsertionAction-Via"></a>
The list of network function groups and any edge overrides for the chosen service insertion action. Used for both `send-to` or `send-via`.  
Type: [Via](API_Via.md) object  
Required: No

 ** WhenSentTo **   <a name="networkmanager-Type-ServiceInsertionAction-WhenSentTo"></a>
The list of destination segments if the service insertion action is `send-via`.  
Type: [WhenSentTo](API_WhenSentTo.md) object
