Last week, I concentrated on how to use Cisco Prime Infrastructure to do troubleshooting for your network. Today, as the 5th and final post of my 5-part blog series, I’ll look at how to maintain network health for your branch site users with Prime. As a quick recap, here’s my blog series on how to set up networking with Prime for a new branch site.
As designed, you have successfully brought up your new branch site and the network is now in production. And you are well prepared to troubleshoot if anything goes wrong. Before you declare “mission accomplished”, there is one more step you can take to achieve long-term success. Just like preventive healthcare can help a person to stay healthy, Prime gives you a number of tools to monitor and maintain your network health. By making full use of these tools, you are prepared to address potential issues before they impact your network.
With Prime, you can
– Keep track of network changes with network topology maps and Device 360° Views;
– Maintain centralized visualization across multiple Prime instances with Operations Center ; and
– Stay engaged with Cisco support integration.
One of the things that always excites network engineers and managers is an accurate network topology map. Prime Infrastructure can provide such a map for you, which includes all your branch sites and main campus site. If there are any changes, you’ll know right away. Or, if you want to know more details, you can drill down to each networking device with Prime Device 360° View. The chart below shows a portion of Cisco’s production network topology map. Read More »

Interop is just around the corner. I am sure there will be plenty of thought provoking content about how to transform IT, compelling demos, and SDN everywhere. But let’s not forget the reality of most IT organizations today.
The majority face the fact that digital innovation is overwhelming their enterprise network. Everything from internal and external Web apps, SaaS, HD video, software updates, mobile apps and even digital signage are traversing the network eating up valuable bandwidth. Analysts even predict that average enterprise bandwidth requirements will increase by up to 50% per year while 60% of WAN budgets are flat or declining.
In addition most enterprises seem to subscribe to doing more with less – particularly when it comes to IT – so upgrading enterprise network bandwidth across locations every few years just isn’t viable – both from a budget and agility perspective. That is not to mention that a lot of enterprises can’t upgrade their bandwidth even if they wanted to due to branch location. Read More »

Last week, I went through application assurance with Cisco Prime Infrastructure. Today, as the 4th post of a 5-part blog series, I’ll go into troubleshooting for your branch site with Prime. Again, as a quick recap, here’s my blog series on how to set up networking with Prime for a new branch site.
By now, your new branch site is in perfect condition with Cisco IWAN, wired and wireless Converged Access, as well as application assurance all working as designed. But you need to be prepared to start troubleshooting if something goes wrong. Every user who runs into network issues means productivity loss. Every minute of a down network causes a significant amount of business loss. Fortunately, Cisco Prime Infrastructure gives you many tools, so you can achieve speedy problem resolution and provide outstanding user experience.
Here’s a Prime troubleshooting success story that a customer told me. It’s a hospital in Dallas, Texas. Keeping their wireless network running was a critical business priority because the medical staff depended on it for communications and patient care. One day, nurses reported intermittent wireless problems in a room. You know, intermittent problems can be hard to troubleshoot. When you are ready to diagnose the problem, the symptoms may or may not exist anymore. Using Prime, their networking team was able to narrow down to a laptop which was always present when the wireless problems occurred. As it turned out, it was doing heavy and unauthorized live streaming which hogged the wireless bandwidth. The owner was immediately notified to stop streaming. Problem solved and case closed.

Last week, I discussed with you how to set up and managed converged wired and wireless access with Cisco Prime Infrastructure. Here, as the 3rd post of our 5-part blog series, I’ll focus on how to ensure application performance for your branch site users with Prime. Again, here’s my blog series plan on how to set up networking with Prime for a new branch site.
Your new branch network is up and running as planned. Everything for your WAN, wired and wireless access is working beautifully. But how is your business application performance? At the end of the day, it’s all about the applications and user experience.

Catalyst 4500E Supervisor 8-E now supports Converged Access with the IOS XE 3.7 release. The Supervisor 8-E is the latest generation high performance supervisor for Catalyst4500E and provides cutting edge features such as Service Discovery Gateway and support for SDN Openflow in addition to Converged Access and industry leading scale and performance. Miercom recently tested the performance of Supervisor 8-E and the report can be downloaded here. Since its launch, the Supervisor 8-E has become the highest selling supervisor in modular access and has been deployed by a large portion of the Catalyst 4500 install base.
The integrated wireless functionality for Converged Access on Supervisor 8-E is implemented through the same Unified Access Data Plane (UADP) ASIC as in the Catalyst 3850, so Catalyst 4500E customers who deploy Converged Access get the same field tested solution that has been deployed by thousands of Catalyst 3850 customers. Additionally, the Converged Access solution on Supervisor 8-E provides high availability (Access Point Stateful Switchover) and investment protection for wireless, which are the hallmark of the Catalyst 4500 platform.
