Cisco CEO Chuck Robbins told CNBC on Friday he was pleased with the company's performance in what he called "a tough macro environment."

"We had a very solid quarter with 4 percent top-line growth, 9 percent EPS, very strong gross margins, as well as operating margins at a nine-year high," he told CNBC's "Squawk on the Street." "As we guided Q2, we obviously guided down, but we also guided a reasonable growth quarter."

Cisco said it expects fiscal second-quarter sales will be in a range of flat to up 2 percent year over year. Robbins cited "the uncertainty of the macro environment and currency impacts."
