Configuration

Map the Interfaces

Step-by-Step Procedure

  1. Map the heth-0-0 physical port to the FPC0 interface.

  2. Map the heth-0-1 physical port to the FPC0 interface.

Configure the Layer 2 Datapath

Step-by-Step Procedure

  1. Configure VLANs for the LAN-side interfaces.

  2. Configure the LAN-side front panel ports and add them to the LAN-side VLAN.

  3. Configure the internal-facing interfaces as trunk ports and add them to the LAN-side VLAN. The internal-facing interfaces are typically trunk ports, as they must support traffic from multiple front panel ports and VLANs.

Configure the Layer 3 Datapath

Step-by-Step Procedure

  1. Map the ge-1/0/1 interface to the NFV backplane:

  2. Configure VLAN tagging on ge-1/0/0:

  3. Configure VLAN tagging on ge-1/0/1:
