Cisco certification would be nice if you can get a job as a Cisco Engineer. But as a windows sys admin (not a network engineer) i always considered cisco to be backwards and overly complicated in their administrative methods (and yes i can use a command prompt).

Where i am, Cisco roles have always been very hard to break into unless you happen to know someone who JUST HAPPENS to have a spot open. Usually the companies big enuff to use cisco would also want some kind of minimum experience so to me just doing cisco certification of your own bat could just be a massive waste of money.
