There seems to be much mystique and confusion over Cisco’s ACI and how we as network analysts will troubleshoot in this new network environment. It’s an architecture to which few seem to have completed the move, but many are planning to do so in the near future. Now is the time to architect with visibility in mind.
With Cisco ACI there has been some misunderstanding based on early claims of ‘not needing packets anymore’ to discussions on ’how the heck are we going to do this?’ Eager to confirm my beliefs about ACI, I attended many sessions at the Cisco Live conference this year. There was a lot of clarification and confirmation of how to best instrument new networks for full visibility.
The Short Answer: Not much has changed as far as building a visibility fabric. If you have familiarity with building such a fabric in the VMware Nexus ‘Top of the Rack’ design, you will have no issue capturing in an ACI environment. Wherein the Nexus model, to get east-west traffic, you would simply tap the uplinks between the top of the rack and the aggregation layer, in an ACI environment you tap between the spine and leaf switches to obtain traffic.
This week we will speak with Steve Brown and Warren Caron of Viavi Solutions, who are their Director of Solutions Marketing and Solutions Engineer, respectively.
With network teams increasingly involved in all aspects of security from threat prevention to breach investigation and remediation, understanding how to be proactive is critical. In this week's LMTV LIVE, we’ll discuss how network pros can more effectively work with security teams on threat prevention, investigations, and cleanup efforts.
Proactively ID anomalous network behavior
Recognize malware, ransomware, and DDoS
Assess damage post-attack
Reconstruct or playback breaches
Ensure successful remediation
Overcoming key visibility and intelligence issues
Strategies to ensure security events are fully captured
These bloodcurdling tales of IT terror will give you chills and send you scrambling for your monitoring tools.
The Case of the Disappearing Network
Let’s face it, nothing’s worse than logging on to find that your entire network has made like Houdini and disappeared from the face of the earth. But that’s exactly what happened to Peter Lee at Northern Devon Healthcare in the UK when a legacy switch went bump in the night.
“One day, we came in and lost the whole network. It was completely gone.”
“About 6 years ago, there were a number of legacy Cisco 3500XL series switches in existence on the campus,” says Lee, Network Technology Specialist at Northern Devon Healthcare. “I suspected as soon as I started working here that they could be a potential source of problems. One day, we came in and lost the whole network. It was completely gone.”
Let your network technology needs and voice be heard!
Nine (9) years ago the team that brought you the Observer platform of performance management tools decided that they needed input from those that fought the Network Wars every day and they started the “State of the Network” survey to gain insight into your everyday needs and the demands placed on you.
Every year, for 9 years, your valued input through this survey has led Viavi Solutions (formerly Network Instruments) to develop better solutions to aid Network Managers in their daily efforts to better support, secure, and troubleshoot the network!
Your participation in this survey helps everyone and your input is very valued!
Your time and opinion will be rewarded by receiving a $5 Starbucks gift card and early access to the report.
This year’s survey is focused on your daily demands, and the needs you have in your daily fight to keep your network (including cloud applications) running and secure, which is a seemingly never ending battle. Viavi Solutions wants to develop more and better technology to help you in supporting a constantly evolving network.
So, take the few minutes to fill this survey out, get an expensive cup of coffee and help Viavi build better solutions to aid you in the never ending need for a safe and secure network!
