Add inline interfaces to Layer 2 Engines

There are two interfaces in an inline interface. The traffic is forwarded from one interface to the other.

The traffic that the Layer 2 Engine allows goes through the inline interface as if it was going through a network cable. The Layer 2 Engine drops the traffic you want to stop.

Inline interfaces are associated with a Logical Interface element. The Logical Interface is used in the Layer 2 Engine Policy and the traffic inspection process to represent one or more Layer 2 Engine interfaces.

    • Select an existing Logical Interface element from the list.
    • Click Select and browse to another Logical Interface element.
    • Click New to create a Logical Interface element, then click OK.
  8. If you want the Layer 2 Engine to inspect traffic also from VLANs that are not included in the engine’s interface configuration, leave Inspect Unspecified VLANs selected.
