I think he’s referring to certain enterprise switches and other networking gear that has basically zero support for automation.
For me personally, I would be replacing that equipment but some businesses would rather pay a few hundred bucks every year + manpower to replace the certs than a few thousand once to replace the equipment.
The only network you’re likely to use that actually follows the OSI model is the CAN bus inside a car. And that’s starting to get replaced by DoIP, which uses the IP model (link layer, internet layer, transport layer, application layer, note the lack of session & presentation layers and combination of the physical & data-link layers into the link layer).

…you don’t need your networking gear to support this in any way
Yeah, this is about 5 layers above that in the OSI model
