Example: Layer 2 Engine Inline Interfaces in inline mode
An example of deploying a Layer 2 Engine in the traffic path in inline mode.
The following illustration shows the interfaces of the inline Layer 2 Engine.
In this example, the IP address on Interface ID 0 is configured as the Control IP address for management connections. Interface ID 1 and Interface ID 2 are an inline interface pair that share the Logical Interface, called Inline. Traffic comes in through Interface ID 1. Any traffic that is the Layer 2 Engine allows leaves through Interface ID 2.
The administrator does the following:
- Creates a Single Layer 2 Engine element and selects the Log Server to which the Layer 2 Engine sends its log data.
- Creates a Logical Interface called Inline for the Inline Interface pair.
- Defines Interface ID 0 as a normal interface and adds an IP address to it.
- Defines Interface IDs 1 and 2 as an inline interface pair and selects the Logical Interface called Inline for the pair.
- Saves the initial configuration of the engine in the Management Client.
- Connects the network cables to the appropriate physical interfaces on the engine.
- Maps the interface IDs to the physical interfaces in the Secure SD-WAN Configuration Wizard and makes initial contact with the Management Server.
- Installs a Layer 2 Engine Policy in the Management Client to transfer the configuration to the engine.
