In May 2015, Cisco CEO John Chambers announced that he would step down to retire, letting Cisco veteran Chuck Robbins take the stage. Robbins has been with Cisco since 1997, and prior to taking over as CEO, he served as the company’s senior vice president of worldwide operations.

Since, the company has undergone some major restructuring and executive rearrangement. Robbins has been helping with the company’s ongoing efforts in switching its focus onto four key areas: security, Internet of Things (IoT), networking, and cloud.

Part of achieving this goal has caused Cisco to layoff 5,500 employees in August — 7 percent of its workforce. But there's been change in the top ranks as well, as some executives saw the transition as a good time to start new career phases.

Here are the executives who have either been replaced or willingly left since CEO Chuck Robbins has taken the reins of the company.

As Robbins prepared to take the throne as Cisco’s new CEO, Cisco presidents Rob Lloyd and Gary Moore chose to depart. Analysts had considered them to be prime candidates to take over for Chambers.

Robbins didn’t fill their roles, opting for a smaller leadership team that would report directly to himself. This was the first of many executive changes to come under Robbins.

Moore now serves as an executive in residence at the Ohio State University where he lectures at the business school. Lloyd went on to become CEO of startup Hyperloop One, which is developing systems to transport cargo and eventually people at high speeds in a levitated pod through a low-pressure tube. Hyperloop One recently raised $50 million and settled a high-profile lawsuit filed by former executives.

In June 2015, Chuck Robbins came out with his 10-member executive lineup — a few less than Chambers’ 13-member team. CTO Padmasree Warrior, Globalization Chief Wim Elfrink, and Senior Vice President of Services Edzard Overbeek would no longer be a part of the team.

Padmasree has since joined Microsoft’s board of directors, and more notably, became CEO of Chinese electric car startup NextEV. After his 18 years at Cisco, Elfrink founded and serves as president of WPE Ventures Digitized Solutions, which focuses on security and IoT. Overbeek is the CEO of a location cloud platform company called HERE, which focuses on digital mapping, autonomous driving, and IoT.

As Cisco confirmed there would be changes to its service provider organization, its management team continued to shift as well. This meant that Kelly Ahuja, senior vice president of Cisco’s service provider business, would be replaced by Yvette Kanouff. Kanouff was and still is in charge of its expanded service provider group, combining network functions virtualization (NFV), mobile networking, service provider cloud, and service provider video.

Ahuja, who was an 18-year Cisco veteran, has re-emerged as CEO of Versa Networks.
