Cisco confirmed that the networking problem Duke University experienced involving Cisco's wireless network and Apple's iPhone was caused by a Cisco network issue. Cisco says it has worked closely with Duke and Apple to identify the source of the problem.
A two-sentence e-mail from a Cisco PR spokeswoman to Network World confirmed the problem was caused by a "Cisco-based network issue."
"Cisco has provided a fix that has been applied to Duke's network and the problem has not occurred since," according to the e-mail.
No other details were provided, and no reply has been received yet to an e-mail and two phone requests to Cisco for more details. No additional details have been provided by Duke University or by Apple.
The wireless problem crystallized exactly a week ago, on Friday, July 13 as it happens, when Duke's IT staff identified the source of intermittent floods of Address Resolution Protocol (ARP) requests as at least two Apple iPhones connecting via the phone's built in wireless LAN adapter to Duke's campus-wide net. The ARP floods, up to 30,000 requests per second, knocked offline sometimes as many as 30 access points, for between 10 and 15 minutes.
That conclusion was based on an early analysis of traffic trace data by Duke IT staff. Frank Miller, assistant director, communications infrastructure, with Duke's Office of Information Technology, was firmly convinced that the iPhone was the instigator. "I don't believe it's a Cisco problem in any way, shape, or form," he said at the time.
The Cisco spokeswoman's e-mail said Cisco "worked closely with Duke and Apple to identify the source of this problem."

Technology adoption increases business growth
According to a study by Cisco, companies that actively try to promote use of new technologies alongside more flexible working conditions, are more likely to successful than those that don’t.
Cisco polled more than 600 business and IT directors across the UK, representing companies with staff of 20-1,000 employees.
They found that those companies that actively utilised technology as a strategic asset, such as Wi-Fi, as well as allowing remote or home networking, were much more likely to have increased turnover by more than 15% over the past year.
However, the study also underlined that the use of technology for improving business efficiency and working conditions had to be directed by senior management, and that the company had to have a clear idea of where and how to invest in technology before implementing it.
Additionally, while a significant number of managers responding to the poll highlighted talent acquisition retention in employees as a major priority, actual working environment conditions were regarded as low priority.
This was especially in the case of home networking, with far fewer companies willing to allow employees to work from home than was necessarily required.
