Many firms have seen production delayed because of a lack of semiconductors, triggered by the Covid pandemic and exacerbated by other factors.

Cisco chief Chuck Robbins told the BBC: "We think we've got another six months to get through the short term.

"The providers are building out more capacity. And that'll get better and better over the next 12 to 18 months."

That expansion of capacity will be crucial as advances in technology - including 5G, cloud computing, the internet of things and artificial intelligence - drive a big increase in demand.

Last month, the Shadow Brokers published firewall exploits, implants, and hacking tools allegedly stolen from the NSA's Equation Group, which was designed to target major vendors including, Cisco, Juniper, and Fortinet.

A hacking exploit, dubbed ExtraBacon, leveraged a zero-day vulnerability (CVE-2016-6366) resided in the Simple Network Management Protocol (SNMP) code of Cisco ASA software that could allow remote attackers to cause a reload of the affected system or execute malicious code.

It is the highest levels of partner certifications from Cisco.
