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.
In certain circumstances, modification to the interface parameters does not immediately take effect, and
therefore, you need to shut down the relative interface to make the modification work.
Note that in case of a double Combo port, only one interface (either the optical port or the electrical port)
is active at a time. That is, once the optical port is active (after you execute the
undo
shutdown
command), the electrical port will be inactive automatically, and vice versa.
Examples
# Shut down interface Ethernet 2/0/1.
[Sysname] interface ethernet 2/0/1
[Sysname-Ethernet2/0/1] shutdown
# Bring up interface Ethernet 2/0/1.
[Sysname] interface ethernet 2/0/1
[Sysname-Ethernet2/0/1] undo shutdown
