[Sysname-GigabitEthernet0/0]
# Create Ethernet subinterface GigabitEthernet 0/0.1 and enter GigabitEthernet 0/0.1 subinterface
view (assuming that GigabitEthernet 0/0 is a Layer 3 Ethernet interface and the subinterface does not
exist).

A
fter you change the link mode of an Ethernet interface, all the settings of the Ethernet interface are
restored to their defaults under the new link mode.
Examples
# Configure GigabitEthernet 0/0 to operate in Layer 2 mode.
