Procedure
1.
Run system-view
The
system view is displayed.
2. Run interface interface-type interface-type interface-number[.subinterface-number]
The
interface view or sub-interface view is displayed.
·
Only Huawei S5720-EI, S5720-HI, S5730-HI, S6720-EI, S6720-HI, and S6720S-EI support
Ethernet sub-interfaces.
·
Only hybrid
and trunk interfaces on the preceding switches support Ethernet sub-interface
configuration.
·
After
you run the undo portswitch command
to switch Layer 2 interfaces on the preceding series of switches into Layer 3
interfaces, you can configure Ethernet sub-interfaces on the interfaces.
·
After an
interface is added to an Eth-Trunk, sub-interfaces cannot be configured on the
interface.
·
VLAN
termination sub-interfaces cannot be created on a VCMP client.
3. (Optional) On an
Ethernet interface, run undo portswitch
The
interface is switched to Layer 3 mode.
By default, an Ethernet interface works in
Layer 2 mode.
Only the S5720-EI, S5720-HI, S5730-HI, S6720-EI, S6720-HI, and S6720S-EI support
switching between Layer 2 and Layer 3 modes.
4. Run ip address ip-address { mask | mask-length }
A
primary IP address is configured for the interface.
By
default, no IP address is configured for an interface.
Each
interface has only one primary IP address. If you configure a new primary IP
address for an interface, the original one is deleted and the new primary IP
address takes effect.
