How to refresh Ethernet interface?

I need to run a bandwidth test with my router out of
the path, to compare its speed with the speed when the
router is in. I recall there's some Linux command
that will recycle the Ethernet interface after I
disconnect the cable from the router and plug it
directly into the modem. In the absence of
this capability, I'd have to reboot the system.
What is the command?

ifdown eth0; ifup eth0
or maybe
ifconfig eth0 down; ifconfig eth0 up
or
/etc/init.d/networking restart

A wise man cannot be insulted. If the insult has no meaning, he ignores
it. If the insult does have meaning, he deserves it.

ifdown eth0 && ifup eth0 (or service network restart,
depending on the distro).

If it's a cable modem behind the router, that's all
that should be needed. If it's a dsl modem, and the
router is doing the pppoe login, the connection type
will have to be changed. That's usually easiest to
do by deleting the network connection setup, and
recreating it using the distros config utilities.
