CTS 353: Introducing the EX4000 (Sponsored)






https://youtu.be/JZKWQKZ3_Zo




This episode on the EX4000 is sponsored by Juniper Networks.



Rowell, François, and Abhi discuss the release of the EX4000 switch from Juniper Networks. Abhi, a product manager at Juniper, shared that the switch will be available on February 12th, just in time for Valentine’s Day. The switch will come in various models, including 8, 12, 24, and 48 ports.



Also discussed is the importance of switching in network infrastructure and the need for upgrades to support new access points like the AP47s.



What’s new with the EX4000 is how quick the boot time is. 2 minutes for the EX4000 to get up and running.



Another great benefit of the EX4000 is it is much quieter from the other EX switch line. This switch would go well in open office environments. It’s also perfect for higher education or retail environments.



Out of the box the EX4000 will support CloudX and have additional telemetry. To work natively with the Mist cloud.



It still operates on the same Junos and will be easily managed in the Mist dashboard.

CTS 352: Networking with Nile (Sponsored)











Austin, from Nile Secure, joins us on the show to talk about how Nile is disrupting the networking industry. We talk about the complexity and challenges people face in managing and scaling their networks.



What we were interested in learning about is how Nile Secure differentiates themselves in the industry. Especially, when it comes to network automation.



We know that it can be difficult to find engineers who are good at both automation and network engineering.



Where some companies fail is on their network automation initiatives. Many have the goal of automating more than half of the manual tasks. But how easily can this be achieved?



Austin describes how Nile Secure has built a cloud-native network operating system that runs on their own hardware to deliver predictable outcomes. Where automation tasks start from day 0.



Where Nile Secure places a strong focus is on network security. Implementing Zero Trust while eliminating the complex configurations that come with it.

CTS 341: Meter Command – Dynamic and Adaptive Network Management (Sponsored)


https://youtu.be/8u0hXi-tMIk




Meter is going one step beyond AI chat bots with their product Command. It’s a generative UI that goes beyond command line interface and adds visuals to create custom dashboards using a natural language interaction.



A network operator can make queries for their network, configure SSIDs, new networks, and other network changes by using plain English.



Meter Command allows a network operator to be highly efficient and productive. A simple English query can yield results of the network. Or if you need to build a custom dashboard for a CTO, you can ask Meter Command to build that for you. No extra coding experience required.



Another great aspect of Meter Command is it is built to be collaborative with other team members. Troubleshooting can be kept in a single canvas and updated dynamically. Dashboards can be created and modified on the fly by collaborating with other team members.
