To achieve this goal i decide to create and upgrade the cluster in my company lab and then i will restore the last backup from the single-node appliance when i will install the new cluster to the customer datacenter. Obviously i cannot use the customer network settings in my lab otherwise i will never reach the Cisco public catalog server useful for the system upgrade but i need to find a way to modify those network setting after the initial setup. http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-4/ Thu, 20 Mar 2025 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-4/ The last part of the guide “How to upgrade your Catalyst Center :)” relate on the upgrade itself and how to restore the whole system in case a disaster happens! Before you start the final step of your upgrade, i suggest you to do 2 simple things: Create a bootable usb drive with the iso file of the starting version Create a proactive Cisco support request In case something went wrong during the upgrade, you will need to re-install the whole application from scatch. http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-3/ Thu, 27 Feb 2025 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-3/ The third part of the guide “How to upgrade your Catalyst Center :)” is all about backup. Before you start the system upgrade you need to run a backup depends on what you need to backup. You can run 2 different type of backup: A system and configuration backup called “Cisco DNA Center (without Assurance data)” A system and configuration + Assurance data backup called “Cisco DNA Center (All data)” Important note about backup: a backup file of a specific Catalyst Center version cannot be used to be restored in a different Catalyst Center version. http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-2/ Wed, 29 Jan 2025 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-2/ The second part of the guide “How to upgrade your Catalyst Center :)” relate to validation tool. There are 2 different tools, depending on you starting version, GUI validation tool (recent version) or CLI Aura tool (older version). Aura tool Aura tool is a CLI tool that allow you to run many validation task inside your maglev shell and provide you a report in PDF file format. This report show you all the test ran and provide you the result of every check, indicating what kind of error is present: Detailed information about how to use Aura tool is here: https://www. http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-1/ Thu, 16 Jan 2025 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-system-upgrade-part-1/ Last November Cisco published the new Catalyst Center golden image, 2.3.7.7 that include some new features and improvements like: Dark Mode AIOps: Event Analytics, Over the air sniffer, AP power savings insights NetOps: Campus Automation, configuration visibility and control, 3rd party device support SecOps: Improved endpoint visibility, LAN automation DevOps: API enhancements including new APIs …and more For all the details you can, as usual, refer to the release notes at https://www. http://next-hop-self.it/posts/ei-catalyst-center-lab-environment/ Tue, 12 Nov 2024 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-lab-environment/ In the last post i spoke about how to upgrade a switch image through Catalyst Center usgin SWIM (Software Image Management) feature, this time i want to dig into the sd-access lab environment. Sd-access networks involved many components, physycal and/or virtual, licensing and design aspects so you MUST overthinking about all the parts, the final design you want to achieve, how you can achieve it and what kind of devices, license type, external services you need to achieve it! http://next-hop-self.it/posts/ei-catalyst-center-switch-upgrade-with-swim/ Mon, 28 Oct 2024 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-switch-upgrade-with-swim/ In the last days i read about Cisco IOS XE 17.9.x End-of-Sale and End-of-Life announcement by Cisco (https://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/ios-xe-17/ios-xe-17-9-x-eol.html) so i decide to take advantage of this bulletin to upgrade the switch in my SD-Access lab using the SWIM (Software Image Management) feature. First of all i need to sync my Catalyst Center (version 2.3.5.5) to Cisco image repository in order to download the latest image catalog: After that i need to choose the Family product i want to upgrade and mark as “Golden” the image version that i want to run in my devices: During this activity you can also download some specific SMU (Software Maintenance Upgrade) for the main image version: Once the image download has finished i can proceed with the switch upgrade. http://next-hop-self.it/posts/ei-catalyst-center-l2-handoff/ Fri, 07 Jun 2024 10:00:06 +0100 http://next-hop-self.it/posts/ei-catalyst-center-l2-handoff/ In the last few months i had the opportunity to create from scratch an sd-access network as company’s internal lab (many many thanks to my company for purchasing a Catalyst Center server - formerly DNA Center, some Catalyst 9300 and a 9800 WLC) and one of the most interesting task i accomplished is L2 handoff. L2 handoff allow you to export a fabric L2VNI (fabric vlan) into a classic vlan in your legacy network, in few words is a simple and intuitive method to integrate your classic LAN with a fabric and starts the migration from the older environment to the newer one.
