Cisco talked about the management choice between Meraki & DNAC, but shows separate part numbers on the data sheet:
CW9166I-x: Cisco Catalyst 9166 Series
Regulatory domains: (x = regulatory domain)
CW9166I-MR: Cisco Catalyst 9166 Series, w/Meraki
Cloud-managed version using Meraki Dashboard
But then it says in the datasheet:
"Cisco Catalyst 9164 Series Access Points can be managed either on-premises with Catalyst 9800 Wireless Lan Controllers (WLC) or cloud-managed through the Meraki dashboard. Customers have the flexibility to deploy these access points in one persona and shift to a different persona in the future."
So will it be a single SKU that can be moved around Meraki & DNAC or separate SKUs which cannot be converted among the two?
