Configuration restrictions and guidelines
• 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 vice versa.

Command Remarks
1. Enter system view.

4. Assign an interface to the

entry.
port inline-interfaces id
By default, an interface does not belong
to any inline Layer 2 forwarding entry.
Two interfaces must be assigned to a
forward type inline forwarding entry
while only one interface is required for a
reflect or blackhole type.

Available in any view.
Forward-type inline Layer 2 forwarding configuration example
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.
