Step Command Remarks
4. Set the duplex mode of
the interface.
duplex { auto | full | half }
Optional.
By default, the duplex mode is auto.
5. Set the port speed.
speed { 10 | 100 | 1000 |
10000 | auto }
Optional.
By default, an Ethernet interface
automatically negotiates a speed with the
peer.
GE fiber ports do not support the 10 or
10000 keyword.
10-GE fiber ports do not support the 10,
100, or 1000 keyword.
GE copper ports do not support the 10000
keyword.
6. Restore the default
settings for the interface. default
Optional.
Shutting down an Ethernet interface
CAUTION:
Use this command with caution. After you manually shut down an Ethernet interface, the Ethernet interface
cannot forward packets even if it is physically connected.
You might need to shut down and then bring up an Ethernet interface to activate some configuration
changes, for example, the speed or duplex mode changes.
To shut down an Ethernet interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface
view or port group view.
• Enter Ethernet interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
To shut down an Ethernet interface ,
enter Ethernet interface view. To shut
down all Ethernet interfaces in a port
group, enter port group view.
3. Shut down the Ethernet
interface.
shutdown By default, Ethernet interfaces are up.
Configuring generic flow control on an Ethernet interface
You can avoid packet drops on a link by enabling generic flow control at both ends of the link. The flow
control function enables the receiving end to require the sending end to suspend sending packets when
congestion occurs.
An interface implements generic flow control by sending and receiving common pause frames. The
following generic flow control modes are available:
• TxRx mode—Enables an interface to both send and receive common pause frames.
