Under Chambers' leadership, Cisco navigated treacherous waters from the dot-com bubble to the rise of the cloud and software-based markets and sales strategies. Cisco grew from $1.2 billion in revenue to $47 billion while Chambers was CEO.
Chambers stepped down as Cisco chairman during the company's annual shareholders' meeting last month, leaving leadership responsibilities solely with CEO Chuck Robbins, who was elected to the company's board.
"You're the cornerstone in our history," Robbins said to Chambers during the meeting. "No other person is more responsible for Cisco's significant technological and societal contributions, and you'll always be a part of Cisco just as I imagine Cisco will always be a part of you."
