The LB module replaces the VLAN tag of the packet with its own VLAN tag and then handles the packet
according to security settings.
The LB module replaces its VLAN tag of the packet with that contained in the interface number of the
egress subinterface and sends it to the switch (the egress subinterface is found through a MAC address
table lookup).
The switch forwards the packet toward the destination.

Configuring inline Layer 2 forwarding
• Forward type: A complete configuration contains an ID, which uniquely identifies an inline Layer 2
forwarding entry, and two interfaces. A packet coming from one interface goes out of another.
• Reflect type: A complete configuration contains an ID, which uniquely identifies an inline Layer 2
forwarding entry, and one interface. A packet received on the interface goes out through this
interface.
• Blackhole type: A complete configuration contains an ID, which uniquely identifies an inline Layer
2 forwarding entry, and one interface. A packet received on the interface is discarded.
