CFO Scott Herren noted in a statement that Cisco continues "to grow deferred revenue in double-digits through the shift to more software and subscriptions."

Tech analyst Patrick Moorhead noted that, in addition to its double-digit growth in security sales, Cisco also reported strength in Cat 9K, data center switching, wireless and Webex portfolio numbers.
"For webscale customers, it was the 5th consecutive quarter of rapid order growth increasing to triple digits," Moorhead added. "This is important as these customers had walked away in many parts from Cisco opting for their own designs. In a very rough period for infrastructure providers, I believe Cisco proved its resilience by balancing infrastructure against software, security and collaboration businesses."
Cisco on Tuesday also declared a quarterly dividend of 37 cents per common share.
For the third quarter, Cisco expects revenue growth of 3.5 percent to 5.5 percent year-over-year.
