In this edition of our SD-WAN series I’m going to take a step away from our lab environment and attempt to address a question I get a lot from our customers. “How do we integrate a SD-WAN router or pair of SD-WAN routers into our current environment?” Well the answer I’m afraid is the networking consultants classic line of “It depends”. And it really does, Cisco’s SD-WAN solution was created by engineers with a background in routing and this routing foundation really gives us a lot of flexibility when positioning our SD-WAN routers into our existing environment.
LookingPoint is an advanced IT infrastructure solution provider founded with one goal in mind: to enable businesses to achieve improved productivity, growth, and business empowerment through the use of technology. We strive to stay at the forefront of technology and to share our knowledge to help businesses run more efficiently. Our team is always looking for new ways to improve the efficiency of our customers’ technology infrastructures, whether it’s in the data center, or for collaboration and networking solutions. Last month we started up a new technology video series designed to share technology basics with IT professionals (and anyone interested in learning about different network technologies). Our Back to Basics series covers everything from what is cloud computing to different routing protocols you can use to optimize your network traffic flow.
Upgrading Cisco software (IOS, IOS-XE, ASA code, etc.) can be a little daunting sometimes. For the most part, installations are straight forward, but there is usually a fair amount at stake. Ideally, your environment should be designed with high-availability in mind, allowing you to perform maintenance (and endure unplanned outages) without business impact. But that isn’t always financially possible, especially for remote sites and smaller branch offices. This makes things especially difficult for the engineers tasked with performing this maintenance remotely. Losing access to a device and watching your continuous ping not receive replies for 5, 10, 15 minutes or even longer sometimes is always taxing! That said, they almost always come back, usually just shortly after real panic starts to set in. While we can’t be 100% sure everything is going to work every time (we didn’t write the code or design the hardware), if we do our due diligence we can increase our chances of success.
On February 2, 2017 Cisco announced a major issue affecting products from their routing, switching, security and server product lines. Reference Tables A through D below for a full list of affected products and part numbers.
