CAUTION:
•
An interface can only belong to one inline forwarding entry, and the last configured port
inline-interfaces
id command on an Ethernet interface takes effect.
• Subinterfaces can be assigned to inline Layer 2 forwarding entries. To make these entries take effect, the
main interface must be assigned to the VLAN of which the ID is used as the subinterface number. For
example, if the subinterface GigabitEthernet 0/1.2 is assigned to an inline forwarding entry, the
interface GigabitEthernet 0/1 must be assigned to VLAN 2 so that the inline Layer 2 forwarding can be
implemented.
• If an interface and its subinterface are assigned to different inline forwarding entries, the forwarding
entry with the main interface takes precedence. For example, the interfaces GigabitEthernet 0/1 and
GigabitEthernet 0/2 are assigned to one inline forwarding entry, and the subinterfaces GigabitEthernet
0/1.2 and GigabitEthernet 0/2.3 are assigned to another forwarding entry; then the data received from
GigabitEthernet 0/1 is forwarded through the interface GigabitEthernet 0/2, and vise versa.

Network requirements
Configure forward-type inline Layer 2 forwarding between GigabitEthernet 0/1 and GigabitEthernet
0/2. Then packets received on GigabitEthernet 0/1 can be forwarded through GigabitEthernet 0/2
directly, and vice versa.
