Shutting Down An Ethernet Interface - HP 3100 Series Configuration Manual

•
Full-duplex mode (full)—Interfaces that operate in this mode can send and receive packets
simultaneously.
•
Half-duplex mode (half)—Interfaces that operate in this mode cannot send and receive
packets simultaneously.
•
Auto-negotiation mode (auto)—Interfaces that operate in this mode negotiate a duplex mode
with their peers.
You can set the speed of an Ethernet interface or enable it to automatically negotiate a speed with its
peer. For a 100-Mbps or 1000-Mbps Ethernet interface, you can also set speed options for auto
negotiation. The two ends can select a speed only from the available options. For more information,

NOTE:
Make sure that the fiber port speed matches the speed requirement of the inserted transceiver
module. For example, after you insert a 1000-Mbps transceiver module into a fiber port, configure
the port speed with the speed 1000 or speed auto command.

Shutting down an Ethernet interface

CAUTION:
Use this feature 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.

Optional.
By default, the description of an interface is in the
format of interface-name Interface. For example,
Ethernet1/0/1 Interface.
Optional.
By default, the duplex mode is auto for Ethernet
interfaces.
The half keyword is not applicable to Ethernet copper
ports that are configured with a 1000-Mbps port speed
and fiber ports.
Optional.
By default, an Ethernet interface automatically
negotiates a speed with the peer.
The 10 and 100 keywords are not applicable to 10-GE
fiber ports.
