The Network After 25 Years of Cisco Live!

#clus1A lot can change in 25 years. At the first Cisco Live (then known as Networkers conferences) in 1989, 200 geeks gathered for the inaugural event. Fast forward to three weeks ago, when we welcomed a whopping 25,000 attendees into the arms of our namesake, beautiful San Francisco.

We heard there was some interest in how the network performed at the show, so I wanted to share some of the interesting statistics about the network at Cisco Live! I shudder at the thought of the ancient network from 25 years ago. So here we go:

This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.

Top 10 Reasons to Upgrade to the 7.4 MD Software Release

As the famous saying goes, “Good things come to those who wait”. Delayed gratification -- person’s ability to forgo a smaller reward now for a larger reward in the future -- has been linked to better life outcomes as demonstrated by the often cited Stanford Marshmallow experiment and others. In most cases though, it requires a degree of self-control not easily achievable in today’s fast paced, ever-changing world with new mobile devices, protocols and technologies.

If you are one of the Cisco Wireless customers currently deploying Release 7.0 MD and waiting for the next Cisco Wireless Software Maintenance Deployment Release, the wait is over!

Release 7.4.121.0 has achieved Maintenance Deployment (MD) status.

Release 7.4.121.0 is the recommended MD release for all non-802.11ac deployments. For 802.11ac deployments, Release 7.6.110.0 (Release 7.6 Maintenance release 1) is the recommended release.

For additional details on Software Release Recommendations and Guidelines, see Guidelines for Cisco Wireless Software Release Migration

Below are top 10 reasons (in no particular order) to upgrade from the current 7.0 MD release to the latest 7.4MD Release.

10. FlexConnect (improved and rebranded H-REAP) with efficient AP upgrade across WAN, BYOD policies support, Flex ACLs and split tunneling. Read More »

Tablets in K-12 Education: Design Your Wireless Network for Tomorrow

Whenever I travel for business, I take my tablet along. It connects me to work email, it plays my favorite music and it allows me to catch up on Red Sox games during baseball season. It is also a filled with pre-K apps for my son to learn his numbers and letters in preparation for kindergarten.

This use of the tablet for engaging young minds is probably no surprise to most parents, and it is no secret that tablets are changing the way our children are learning both in and out of the classroom. More and more schools are interested in ramping up the role of technology in the classroom, and with this in mind, we put together a webinar for K-12 educators on the very topic of tablets in K-12 education.

Using Mobility to free you from the desktop – What we’ve learned about deploying Cisco Unified Mobility

Last week, I described what Cisco Unified Mobility is and what it does for me and the other thousands of employees at Cisco.  Today, let me tell you about the deployment process and what we learned.

Cisco IT Implementation

Cisco Unified Mobility requires our Cisco Unified Communications Managers to be on version 7.1 or above, and we started deploying the service soon after we’d upgraded to 7.1.  We deployed Cisco Unified Mobility in each of our 13 Cisco Unified Communications Manager clusters, rolling out the service on a site-by-site basis. This gradual transition process helped to smooth the impact of supporting users and the potential for spikes in outbound calls as employees began working with the SNR feature.  At first, we worried that a large number of calls going out to mobile phones from Cisco sites might overwhelm smaller outbound trunks, but so far we haven’t seen any problems there.  Also, our gradual site-based rollout made it easy to avoid countries that do not allow outbound calling from our private VoIP network to the PSTN (primarily in the Middle East, and in India).

One implementation decision may be a surprise:

Using Mobility to free you from the desktop – What we’ve gained by deploying Cisco Unified Mobility

A lot of our employees, especially salespeople, seem to work everywhere except at their desks. Reaching them used to mean making multiple calls to multiple numbers, and leaving messages at each one.  And waiting for an important phone call sometimes meant that you were tied to your desk until it came through.

Now, with Single Number Reach (SNR) — a feature of Cisco Unified Mobility —  I can receive business calls wherever I want to  be reached at the moment­--at my desk, at home, or on my mobile phone. And if I can’t answer, Cisco Unified Mobility gets all my messages sent to a single voicemail box.  There’s also a Mobility feature that lets me transfer calls from my office phone to my mobile phone, and back again – without anyone on the other end knowing I’ve changed phones.   This helps when I pick up an important call at my desk, but need to take care of something that takes me away from the desk phone.  Sometimes I’ve got to get in the car and can use my Bluetooth headset to finish the conversation.

My current SNR profile is configured to route calls to my mobile inside of normal working hours, and then to push them to voicemail on weekends.  I even have an access control list (ACL) to allow my manager’s calls to pass through to the mobile number at any day/hour.  He does respect normal work hours but we do know emergencies happen from time to time and it is important to be accessible.

All of these Cisco Unified Mobility features were made available to 80,000 phones in our company, by activating them on in our eighteen production Unified Communications server clusters around the world. The truly impressive thing about the Cisco Unified Mobility service is that it can scale to companies of any size.  The benefits to the individual user apply no matter if you are an 8 or 80,000 person company.  Mobility benefits the individual most.

From our deployment activity, we learned valuable lessons for our customers about implementation decisions, feature adoption by users, and the resulting business benefits.
