If Cisco CEO Chuck Robbins is worried about China's Huawei, he's doing a good job hiding it.

Robbins told CNBC's Jim Cramer on Thursday, following his company's better-than-expected quarterly earnings report, that in markets where Cisco and Huawei go head-to-head selling networking equipment, his company is winning it share of deals.

"We haven't seen any material impact from all of the noise in the system around this topic," Robbins said. "If you look at the numbers and you look at our service provider business in both Europe and Asia, where we compete with them, they were both positive. So we were able to compete."

The noise Robbins is referencing pertains to the many controversies surrounding Huawei, particularly in the U.S., where the company faces a broader ban on its equipment because of security concerns. Huawei has been expanding outside of its home country as it gears up for the deployment of 5G networks across the globe, offering cheaper gear than its Western competitors can provide.

In December, Huawei CFO Meng Wanzhou was arrested in Canada on fraud charges. Prosecutors in New York say Meng and Huawei sought to hide payments made for equipment sold to Iran, a violation of sanctions against that country, and Canada is weighing whether to extradite Meng to the U.S.
