=== CISCO SD-ACCESS - LAB NOTES ===
  * Catalyst Center (DNA, controls ios-xe) needs a lot of resources. Like x40 cpus 150G
  * They've released an OVA for DNA center but very weighty (x200 micro services / containers ) 
    * So **don't use the OVA** file. Take the installer that Cisco gives you to reinstall their physical appliances, which is just an ISO. Mount a VM with the requirements that I just stated. See this [[https://masonreimert.com/2024/06/17/176-nkbbrf/|External Link]]
  * Now switches that are manageable by SD access or by DNA center to use as SD access nodes. **9000V**. So if you have a distributed fabric, you're going to need, you know, four of these Catalyst 9000 virtual switches, which each take 32 gigs of RAM.
