John Chambers steps down as Cisco's CEO

(Reuters) - Cisco Systems Inc Chief Executive John Chambers will step down in July after 20 years at the helm of the network equipment maker, a symbol of the dot.com stock boom 15 years ago now struggling to boost its bottom line in the era of cloud computing. Company veteran Chuck Robbins, 49, will take over as CEO while 65-year-old Chambers, one of the longest-serving leaders of a Silicon Valley company, will become executive chairman and continue to be chairman, the company said on Monday.
