Hi @Richard-Tapp,
Brash and cmr pretty much covered it! This Product End-of-Life (EOL) Policy page is another great reference 🙂
A product's EOL (End-of-Life) and EOST (End-of-Support) date are basically equivalents and reference the same date. When the device reaches EOL/EOST, the product's lifetime warranty period also ends (if it's a product covered by a lifetime warranty, which MS switches are.) Additionally, the device is no longer affirmatively supported by Cisco Meraki (please still feel free to open a Meraki Technical Support case on these devices if needed, but please be aware that this support will be on a best case effort basis and not guaranteed.)
After the EOL/ EOST date, the changes that may occur will include the following:
- Cisco Meraki cannot guarantee that legacy hardware products will be able to connect to the management software indefinitely following the EOST Date;
- Cisco Meraki Technical Support may no longer troubleshoot the legacy hardware products;
- Cisco Meraki may no longer issue firmware updates or patches for the legacy products; and
- New software features available for the management software may not be compatible with the legacy hardware functionality or with the firmware running on the legacy hardware.
Best,
Feli
