how can i shutdown the PHYSICAL interface of an ethernet interface
I would like to shutdown the physical interface of an ethernet interface, without disconnecting the cable that is connected to this interface.
Basically, I would like to shutdown the LED of the ethernet interface.
If I do
ifconfig eth2 down
then the IP address is removed from the routing table, but the LED is still blinking on the interface.
ip link set eth3 off
how can I switch the interface off (so simulate a cable cut ?) without really disconnecting the cable ?
