To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet interface view
interface interface-type

—
Change the description of the
interface
description text
Optional
By default, the description of an
interface is the interface name followed
by the “Interface” string,
GigabitEthernet0/1 Interface for
example.
Set the duplex mode duplex { auto | full | half }
Optional
By default, the duplex mode is auto for
an Ethernet interface.
Optical interfaces do not support the
half keyword.
Set the port speed
speed { 10 | 100 | 1000 |
auto }
Optional
By default, the port speed is auto for an
Ethernet interface.
Optical interfaces do not support the 10
or 100 keyword.
Shut down the Ethernet interface shutdown
Optional
By default, an Ethernet interface is in up
state.
To bring up an Ethernet interface, use
the undo shutdown command.
Configuring an Ethernet subinterface
Ethernet subinterfaces fall into two categories: Layer 2 Ethernet subinterfaces and Layer 3 subinterfaces.
• Layer 2 Ethernet subinterface enables Layer 2 packets to be forwarded across VLANs. By
configuring Layer 2 Ethernet subinterfaces for VLANs, you can forward Layer 2 Ethernet packets
across VLANs through the corresponding Layer 2 Ethernet subinterfaces. Layer 2 Ethernet
subinterfaces are used usually when the device is working with a high-end firewall plug-in card.
• Layer 3 Ethernet subinterface enables Layer 3 Ethernet interfaces to identify packets by VLANs. By
configuring multiple subinterfaces on an Ethernet interface, you can have packets of different
VLANs forwarded through their corresponding subinterfaces, thus achieving flexibility.
Follow these steps to configure an Ethernet subinterface:
