shutdown

Syntax
shutdown
undo shutdown
View

Default Level
2: System level
Parameters
None
Description
Use the shutdown command to shut down an Ethernet interface.
Use the undo shutdown command to bring up an Ethernet interface.
By default, an Ethernet interface is in the up state.
You may need to shut down and then bring up an Ethernet interface to activate configuration changes
in certain circumstances, for example, after changing the speed or duplex mode of the interface.
Of a double Combo interface, only one port (either the optical or electrical port) is active at any given
point in time. When you activate the optical port by using the undo shutdown command, the electrical
port is disabled automatically, and vice versa.
If the active port of a Combo interface is configured with loopback testing, you cannot activate the
other port of the Combo interface with the undo shutdown command.
Configured in interface view, this command takes effect on the current interface only. Configured in
port group view, this command takes effect on all interfaces in the port group.
Use this command with caution. After you shut down an Ethernet interface by using this command, the
Ethernet interface cannot forward packets even if it is physically connected.
Examples
# Shut down and then bring up interface GigabitEthernet2/0/1.

[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] shutdown
[Sysname-GigabitEthernet2/0/1] undo shutdown
# Shut down all Ethernet interfaces in port group group1.
