Oh, neat. Didn't know how to do down and up in one command line without 
writing a script.

Not any real difference from doing a service network restart. When your 
interface goes down, SSH just waits until the interface comes up, and 
then you get all the messages that occurred between those two events. I 
am going to have to note this command for future use (it is kind of like 
an ifbounce command :) ).
