Access licenses get consumed by each unique endpoint. So if 8 devices are being authenticated via 802.1x or MAC-Auth, that would be 8.
If you are using Multi-Host, only one endpoint authenticates, and then the rest get in (not secure) after it. This would be one license.
Multi-Auth mode would allow each to authenticate, using 8 licenses and being more secure. See below:
- Multi-Host is a valid solution if a power-user for example is using many VMs on his PC. After authenticating initially, all VMs can communicate with the network.
- Multi-Auth is more secure because each MAC address accessing the network is controlled.
