It’s always been important to remote workers to have a solution that provides both secure connectivity to their corporate network and simple user experience.With the recent Summer Blockbuster release of the Cisco Wireless Release 8.0, using the OfficeExtend 600 Series Access Points (OEAP-600) just got better. Here are a few of the enhancements that come to OEAP-600 with Release 8.0:
Firewall for personal networking -- Provides port/application protection for personal network traffic that can be controlled by the end user. While the corporate firewall is protecting your corporate data traffic, you now have the capability to make your personal network traffic more secure also with this feature.
Split-tunnel for Internet traffic -- Enables corporate clients to reach the Internet directly through the WAN instead of tunneling the data traffic through the corporate network. Provides the IT administrator the flexibility to configure the level of split-tunnel capability needed for their network. Together with the existing Split-tunnel for Printer feature the OEAP-600 provides maximum flexibility for printing and managing data traffic between the remote & corporate office.
QOS Enhancements for Voice traffic – Assigns high priority for voice packets for remote workers using the OEAP-600 and a VOIP solution in their home or remote office to enhance the remote workers voice call experience. Read More »
This fall your wireless networks will experience many devices upgrading to the new Android 5.0(L-release) and Apple iOS 8 releases (cue: IT managers groan). There have now been many blogs attempting to capture the enhancements expected with these releases. Today I am going to focus on describing how Android L and iOS 8 may affect customers deploying Cisco enterprise grade Wi-Fi networks based upon our research and testing of the Apple seed. Our verdict: Carry on with business as usual.
Here are four features we predict will have the most impact your networks:
1. Chromecast and Google Cast Enhancements (Android L)
Rishi Chandra, the Director of Chromecast Product Management announced that, starting with the Android L release, users have the ability to cast to your neighboring devices such as a TV without having to connect to your Wi-Fi network. In the demo, a phone used the cellular connection to connect to chromecast through the cloud. A variety of techniques are used to authenticate the users in the same room OR use a pin-code as an alternative. Users can Google Cast an ecosystem of applications or even their own applications over any Android or iOS device as well as Cloud based apps on Chrome.
Predicted Impact: Given that this feature works transparently to the Wi-Fi, it is expected that there is no impact on the WLAN in your classrooms or dorm rooms or auditoriums where this will most likely be used.
2. Peer-to-peer AirPlay discovery and playback (iOS 8)
Starting with the iOS 7.1 release, AirPlay devices will discover an AppleTV via the bluetooth network. Users could also secure their AppleTV via a 4 digit pin-code. With the iOS 8 release, Airplay devices can also mirror their content via Airdrop. This feature offers an alternative method for customers to discover and mirroring of Bonjour traffic without accessing the corporate Wi-Fi network.
Predicted Impact: Again this feature operates transparent to the Wi-Fi and therefore customers using this feature should not see any impact on the WLAN. Cisco wireless customers also have the ability to use the Service Discovery Gateway on Cisco IOS based switches, routers or wireless LAN controllers or the Bonjour Services Directory on AireOS controllers.

Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.
Patients are the focus at Johns Hopkins Hospital. Johns Hopkins uses state-of-the-art technology in their hospitals to ensure that patients get the latest advances from surgical tools, radiologic imaging suites with the best diagnostic capabilities to something as humane as sound-absorbing private rooms for each patient.

Wi-Fi roaming is often a tumultuous subject. The crux of the issue is, with Wi-Fi the roaming decision is left to the client.
In the recent years, there have been great strides in improving Wi-Fi roaming with the creation of standards-based roaming technologies. Cisco first pioneered fast roaming many years ago with CCKM (Cisco Centralized Key Management), which was the foundation for 802.11r. 11r which was ratified by the IEEE in 2008, allows for fast roaming, even on a secure 802.1X SSID. With 802.11r it is possible to roam without disruption during a voice or video call.
While client support of 802.11r is largely lacking in the laptop space, there is large support in the smartphone realm. Apple iOS devices have supported 11r since iOS 6 (http://support.apple.com/kb/HT5535). The recent Samsung smartphones, such as the Galaxy S4, S5, and Note 3, also support 11r.
Note: Some non-802.11r clients can react adversely when connected to an 11r WLAN. The current recommendation from Cisco is to have a separate WLAN for 802.11r clients.
802.11k is another amendment from the IEEE that helps to improve roaming. 802.11k provides a whole slew of information to the client, which allows the client to understand the RF environment and make an informed roaming decision. This information can include channel load and AP neighbor lists.
11r and 11k help, however, that does not mean the infrastructure is irrelevant in the roaming picture. With the help of a model train, we did some testing to figure out just how much impact the infrastructure could have. We compared Cisco to one of our competitors, whom we will call Vendor A.
This video summarizes the results and shows the train in action, or continue reading for more details: Read More »
What do WebEx QoS and Phone Troubleshooting have in Common?
If you read my previous blog then you’ll already know that the answer is Medianet. In Part 1 of this 2 Part blog series I discussed the new reverse Metadata capability, provided by a Cisco network, that allows an Enterprise to enable granular QoS marking for all the different media streams that make up a WebEx meeting. In this 2nd instalment, we’re going to take a look at how we can extend Medianet’s Mediatrace capability to Cisco’s 79XX, 89XX and 99XX IP Phone portfolio.
The other recent innovation for Medianet is Prime Collaboration’s ability to now invoke a Mediatrace for a number of IP Phones models that don’t support the MSI (Media Services Interface). As these devices cannot originate Metadata, it has been previously impossible start a Mediatrace through end point selection for telephones in Prime Collaboration. It is now possible, reactively and proactively, to troubleshoot voice quality issues on 79XX, 89XX and 99XX devices, using the same combination of Medianet and Prime Collaboration tools that have previously only been applicable to personal and room based video systems. Take a look at one of my previous blogs, “Medianet in Action”, for some additional background material on video troubleshooting. The demonstration below shows how to start a Mediatrace for a pair of phones.
