I spent 12 years there - from 1999-2011 when I accepted the early out - a fantastic package. Overall, Cisco took good care of me but it probably took 10 years off of my life.
It's the most hectic, high-stress, place to work - bar none. The good ole days of doing more with less are gone.
Now, it's all about doing a ridiculously amount more with a ridiculously amount less. Everyone I know who still works there hates it and wants to find a way out.
