In their highly anticipated announcement this week, Apple introduced two new phones, the iPhone 5C and iPhone 5S, and confirmed that iOS 7 would be released on September 18th. Techies like myself took note that iOS 7 will include quite a number of new features. We at Cisco want to help you understand what iOS 7 means for your network, so here’s a quick blog to sum it up:
How does iOS 7 impact your wireless networks?
Soon your employees and guests will be upgrading to IOS 7. Did you know up to 20% of traffic to mobile devices is software upgrades, application updates and synchronizing your devices via the cloud? Cisco’s Application Visibility and Control technology can help you identify and tame these applications and is available on the routers, Wireless LAN and visible via Prime Infrastructure. In addition, Cisco’s ISR can cache these updates to reserve valuable and expensive WAN bandwidth. More details about protecting the WAN is available in another blog.
If you leverage a Captive Portal, you will experience a change in behavior. Apple has enhanced the Captive Network Assistant (CNA) functionality iOS 7 making it more robust. Cisco has proactively developed and tested a new version of wireless LAN controller code to interoperate with Apple’s new implementation while ensuring a seamless experience for all other clients.
Finally iOS 7 also has significant security and manageability enhancements to improve productivity for the enterprise.
What do you need to do in order to optimize for iOS 7?
If you utilize a Captive Portals in your WLAN, you need to leverage a new feature in the software releases shipping in September 2013:
- AireOS 7.4 MR2
- Cisco IOS-XE 3.2.3
Background on Captive Network Assistant(CNA) and iOS 6?
When connecting to a wireless network; the Apple iOS device sends a request to a specific page on the Apple Site to verify Internet connectivity.
- If the page is accessed successfully, the device assumes it has network connectivity.
- In the event of a failure, CNA assumes a captive portal and launches a CNA browser to prompt the user with the login page.
This functionality was available with Cisco AireOS version 220.127.116.11.
So what changed with iOS7?
With the iOS7, Apple has enhanced the logic around this functionality to make it more robust. To ensure optimal functionality; associated changes have been made in the controller code to detect and respond the CNA packets.
What if I am running AireOS 7.5 release?
A MR release will be made available shortly.
What about older AireOS code versions?
Customers operating with AireOS 7.0, 7.2 and 7.3 should upgrade to 7.4 MR2 to get the benefits of this functionality
What if I have a mix of iOS 6 and iOS 7 devices?
You can operate without problem with the new controller release
What if I do not use the Captive Portal functionality – do I need changes to my controller code?
No. You can continue to manage iOS 7 devices with existing AireOS and Cisco IOS-XE based controllers
So what’s the bottom-line?
To enable that your network is ready for iOS 7 and Captive Portal ensure that you are running the latest Cisco Unified releases.
- AireOS 7.4 MR2 OR
- IOS-XE 3.2.3

Gelişen teknoloji haberleri yapmanız çok güzel teşekkürler
Still not knowing how the iPhone 6 will likely be following the discharge of iPhone 5s ?
No idea about any Apple plans for iPhone6 – all i can point out is that the two announced phones are 11n based
Can you share the details of CNA bypass in 7.4MR2
Instead of looking for that one site success.html; we are looking for UserAgent and allow broader set of sites to be used.
Which version is 7.4 MR2? This is nowhere to be found in the download section.
Hi Curtis and team, the 7.4 MR2 has not been posted but will be sometime within the next 1-2 weeks. An escalation image can be made available through the Cisco sales team now.
What is the impact of not upgrading? Does this only apply to users of captive portal bypass? It is not very clear what the user experience is when using CWA with ISE for guest access.
Here is a link to download 18.104.22.168 WLC software:

7.5 MR availability or download link?
iphone 5s and 5c did not satisfy me. I think apple bumped up against the wall
Any word on when the 7.5 maintenance release will be available?
