Should Software Engineers Seek CCNA's?

kernel2 asks: "I'm in the software engineering profession and some of my friends are about to enroll on a CCNA (Cisco Certified Network Administrator) course and are egging me on to join as well. I'm trying to decide whether I should do the course or not. On the one hand it might help me understand networking (especially in bigger corps) better and that is something I love (networking). It might also help me diversify and improve my chances of landing a job in these strained and difficult times (and that's primarily why my friends are doing it). But wouldn't it look odd on my CV? I mean why would someone highly interested in software (with a Software Engineering degree) do CCNA?"
