Hello
I Created an diagram for clearity:
Each company had is own servers connected with the swicthes from the business center. So they run their own services.
So for example: Laptop company A connect anywhere in the center with an switch port, CPPM should place this device automatically in VLAN 10.
Same for laptop company B, if this device connect with switch he should placed in vlan 20 by CPPM.
So al switches are integrated as network device in clearpass. But how can clearpass join every domain? In the clearpass server administration you can only join 1 AD Domain...
I hope its clear.
