4.3.2.4 Configuring Virtual Interfaces

In addition to physical and IP interfaces, 4Motion defines the following virtual

interfaces. All ACLs configured for filtering traffic destined towards the NPU or

AUs, are attached to either of these interfaces.

 NPU-host: Used for configuring ACLs to filter traffic destined towards the NPU.

 All-AU: Used for configuring ACLs to filter traffic destined towards the AUs in

the 4Motion shelf.

For more information about attaching ACLs to the NPU or all-AUs, refer the

section, “Attaching/De-attaching ACLs to/from an Interface” on page 241.
