Can an IP Address Be Directly Assigned to a Physical Interface?

An MEth management port is a Layer 3 interface. You can directly configure an IP address for the interface.

To configure an IP address for a service interface, configure a VLANIF virtual interface, and assign an IP address to the VLANIF interface. Example:

<HUAWEI> system-view
[HUAWEI] vlan 10 
[HUAWEI-vlan10] quit  
[HUAWEI] interface vlanif 10 
[HUAWEI-Vlanif10] ip address 192.168.1.10 24 

In V200R005C00 and later versions, run the undo portswitch command changes the working mode of Ethernet interfaces from Layer 2 mode to Layer 3 mode. Ethernet interfaces working at Layer 3 support IP address configuration.
