Bringing network interfaces up/down in Linux


Two methods can be used to bring interfaces up or down

1) Using "ip"
Usage:
# ip link set dev <interface> up
# ip link set dev <interface> down
Example:
# ip link set dev eth0 up
# ip link set dev eth0 down

2) Using "ifconfig"
Usage:
# /sbin/ifconfig <interface> up
# /sbin/ifconfig <interface> down
Example:
# /sbin/ifconfig eth0 up
# /sbin/ifconfig eth0 down
