It’s Not The Network

All too often we networkers spend our time defending the network not only from security threats but from blame as the root cause (actual or perceived) of performance problems. The network is guilty until proven innocent. So how do we counter these arguments, put the issue to rest, and uphold the integrity of the network? Logs, logs, logs.

Logs are evidence to support your hypothesis. There are a couple of different types of logs I’d like to talk through and the roles they provide in a tiered approach to troubleshooting.

SNMP – This is one of the first places I go to when an issue is reported. This provides a look at the current state of the network based on polling intervals and traps, and also a place to explore data patterns and trends. Most enterprises will have an NMS solution in place and in my experience this is also a great place to learn the topology of the network(s) when joining a new company. There are many commercial and open source products available and I suggest trying a few different options to find out which works best for you and your team as they all organize and present the data in slightly different manners.

IT professionals and end users. Cui Bono?

As a Senior Network Engineer I’ve seen many end-user issues that look like big problems but are actually very simple. The difficulty lies in a lack of understanding between end users and IT teams who support them. In this article, I want to give some advice to improve communications and relationships between these two groups.

My First Cisco Experience

The last 30 years of innovation at Cisco comes from people, and the amazing things that happen when we connect the unconnected. Cisco Champions are a part of that success. By sharing their knowledge and expertise, Cisco Champions play a unique role in contributing and enhancing the way people use technology. In fact, some Cisco Champions have been in the IT industry almost as long as Cisco! To celebrate innovation then and now, we’ve asked Cisco Champions to tell us about their first experiences with Cisco. Cisco Champions are seasoned IT technical experts and influencers who enjoy sharing their perspectives with the community. The Cisco Champions program encompasses different areas of interest, such as Data Center, Internet of Things, Enterprise Networks, Collaboration and Security. Cisco Champions are located all over the world.

I think it was circa 1998/1999. I had a Novell server running as a router between an Ethernet and a Token Ring network. It was taxing the server and I  needed a solution that would take the load off of my poor 3.1 Novell server. I’m sure I used a 2500 series router to solve my problem. Even running at 10Mbps it was a huge improvement.

Top Cisco Innovations

To celebrate 30 years of innovation at Cisco (#We are Cisco), we’ve asked Cisco Champions what they think is the most important Cisco innovation to date. Cisco Champions are seasoned IT technical experts and influencers who enjoy sharing their knowledge, expertise, and thoughts across the social web and with Cisco. The Cisco Champions program encompasses different areas of interest, such as Data Center, Internet of Things, Enterprise Networks, Collaboration and Security. Cisco Champions are located all over the world.

Here are their top answers.

Cisco Nexus Series
The most important innovation for me is the Data Center Networking Solution with Nexus Portfolio N2K, N5K, N7K, and N9K, that allows us to address all challenges for our customers. I really appreciate the new campus solution based on C6800 with IA switches which uses the same technology as FEX. It really simplifies architecture and reduces OPEX with a single point of management.
