Configuring the intranet interface to work in Layer 2 mode on the firewall

Perform as follows to switch a Layer 3 interface to a Layer 2 interface:
[USG] interface GigabitEthernet 0/0/1
[USG-GigabitEthernet0/0/1] portswitch //Configure the interface to work in Layer 2 mode.
To switch Layer 3 Ethernet interfaces to Layer 2 mode in batches, run the portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view.
By default, a Layer 2 Ethernet interface belongs to VLAN 1 and works as an access port.
