Have you ever heard about two new PoE enhancements that are available on some Catalyst 3850 and all Catalyst 9K platforms? If not, you’re not alone. I only found out about these few months back by accident when I was troubleshooting some issues. There are two great features available for you to configure on PoE-enabled switches:
- Perpetual PoE: preserves power during warm reload
- Fast PoE: provides power to the port after cold start at pre-outage levels
