What other applications does DNA have?Cisco’s DNA Center appliance is generally talked about in the context of SD-Access (SDA), but SDA is a complex technology that involves significant planning and re-architecture to deploy.  DNA Center is not just SDA, though – it has multiple features that can be used on day 1 that can cut down on administrative tasks and reduce the likelihood of errors or omissions.  From conversations with our customers, the most asked-for capability is software image management and automatic deployment, and that is something that DNA Center handles extremely well compared to many other solutions out there. Wait…I can manage software updates with DNA?Managing software on network devices can be a substantial time burden, especially in businesses that have a substantial compliance burden and require regular software updates.  Add to this the increasing size of network device images – pretty much all the major switch and router
Two of the lesser known yet extremely useful features present in the Catalyst 9000 and many other route/switch products in Cisco’s lineup are Guest Shell and Application Hosting. Both of these features rely on Cisco’s use of Linux as an underpinning of their various network OSes and the use of x86 CPUs for their devices as well. As the Catalyst 9000 switches are the most common and accessible, we’ll focus on this platform for now. Guest Shell Guest shell allows the switch operator access to two alternate CLI environments – a Bash shell and a Python 3 interpreter. From these environments, scripts can be written and executed. Further, IOS features like EEM can call Python or Bash scripts, and conversely, these scripts can call into the IOS CLI or the NETCONF API to allow for a significant boost in automation capability. Application Hosting Application hosting is the next step beyond

Automation With RoomKit

Recently, a customer came to us with an interesting problem with their Room Kits…  The Challenge Our client has many Cisco Room Kit installations ranging from large training areas on the Room Kit Pro, to some smaller conference rooms and huddle spaces. Most multi-display video systems have two or more same-sized televisions, generally right next to one another. One screen will show the presentation, the other screen will show the active, remote speaker. The smaller spaces didn’t have enough wall real estate to support two large televisions like the training areas on the Room Kit Pro did.  Instead, a large primary display along with a smaller secondary display, was chosen: When the displays are both the same size and right next to one another, it doesn’t usually matter which one is showing the presentation and showing the speaker. This looked good in visual concept; however, the challenge came in utilizing the
