How to bring the network interface down in Arch

Coming from Debian/Ubuntu camp, I know that ifup eth0 or ifdown eth0 can be used to bring a network interface down/up. Unfortunately, ifup and ifdown is not available by default on an Arch netinstall. Also, it seems like ifup/ifdown are now in the list of deprecated tools. So, what's the alternative? Use ip command, like to bring down an interface do:
#: ip link set eth0 down
Conversely, if you want to bring up an interface, do:
#: ip link set eth0 up

Installing Linux Mint 12 on Virtualbox

Linux Mint 12 was released last 2011-11-12. The release made it to the top of the list in Looking at the outside, Linux Mint 11 and Mint 12 are almost identical except for minor verbiage change.

Linux Mint 12 comes with the following major software:
kernel:  3.0.0-12-generic
X Org:  1.10.4
GNOME: 3.2.1
Firefox: 7.0.1

Below is my configuration of the guest machine:

Name: mint12
OS Type: Ubuntu

Base Memory: 1024 MB
Processor(s): 1
Execution Cap: 100%
Boot Order: Floppy, CD/DVD-ROM, Hard Disk
VT-x/AMD-V: Enabled
Nested Paging: Enabled

Video Memory: 12 MB
3D Acceleration: Disabled
2D Video Acceleration: Disabled
Remote Desktop Server: Disabled

IDE Controller
  IDE Secondary Master (CD/DVD): Empty
SATA Controller
  SATA Port 0: mint12.vdi (Normal, 20.00 GB)

Host Driver: Windows DirectSound
Controller: ICH AC97

Adapter 1: Intel PRO/1000 MT Desktop (NAT)

Serial Ports

Device Filters:
0 (0 active)

Shared Folders

Note: I am using the default configuration except for the memory. I should have enabled 3D acceleration support and increase video memory. But I would like to compare how it compares with the older versions of Linux Mint.

Without too much ado, below are screencapture of Linux Mint 12 install at strategic points

For those familiar with VirtualBox and who have been following along on latest distributions will probably notice that I should have enabled 3D acceleration during the installation. This specially so for GNOME 3.x series window managers.
