Cisco said Chuck Robbins will succeed John Chambers as CEO July 26, marking a change at the top of the US-based technology group for the first time in 20 years.

Chambers, who took over as CEO in 1995, will become executive chairman when Robbins assumes his new responsibilities.

The departing boss laid out the the challenges facing his successor. "Our next CEO needs to thrive in a highly dynamic environment, to be capable of accelerating what is working very well for Cisco, and disrupting what needs to change," Chambers said in a press release.

Robbins joined Cisco in 1997 and held several management positions throughout his career. Most recently he was senior vice president of worldwide operations. He was a key architect of Cisco's commercial business strategy, which grew 8 pc in the last quarter. Robbins also was behind the group's security and collaboration business growth and sponsored several acquisitions.

Chambers, during his tenure at the helm, oversaw an expansion of Cisco's business from 1.2 billion dlrs in sales in 1995 to 48 billion dlrs a year today.
