Examples
# Enter GigabitEthernet 4/0/1 interface view (assuming that the interface is a Layer 2 Ethernet
interface).
<Sysname> system-view
[Sysname] interface gigabitethernet 4/0/1
[Sysname-GigabitEthernet4/0/1]
# Enter GigabitEthernet 4/1/1 interface view (assuming that the interface is a Layer 3 Ethernet
interface).
<Sysname> system-view
[Sysname] interface gigabitethernet 4/1/1
[Sysname-GigabitEthernet4/1/1]
# Create Ethernet subinterface GigabitEthernet4/1/1.1 and enter GigabitEthernet4/1/1.1 subinterface
view (assuming that GigabitEthernet4/1/1 is a Layer 3 Ethernet interface and the subinterface does not
exist).
<Sysname> system-view
[Sysname] interface gigabitethernet 4/0/1.1
[Sysname-GigabitEthernet4/1/1.1]
ip fast-forwarding
Use ip fast-forwarding to enable fast forwarding on an Ethernet interface.
Use undo ip fast-forwarding to disable fast forwarding on an Ethernet interface.
Syntax
ip fast-forwarding
undo ip fast-forwarding
Default
Fast forwarding is disabled on an Ethernet interface.
Views
Ethernet interface view
Default command level
2: System level
Usage guidelines
Fast forwarding is supported on only Layer 3 Ethernet interfaces of routers configured with SAP modules.
Fast forwarding takes effect only when both the receive and send interfaces are enabled with fast
forwarding.
Enabling or disabling fast forwarding on an Ethernet interface of a SAP module restores all
configurations of the interface to the default.
Examples
# Enable fast forwarding on Ten-GigabitEthernet 3/0/2.
<Sysname> system-view
[Sysname] interface Ten-GigabitEthernet3/0/2
[Sysname] port link-mode route
