Binding to a non-access-controlled VSC
When a port is bound to a non-access-controlled VSC, the controller is used for authentication
tasks only. Authentication can occur by checking the user's MAC address or via 802.1X. Access
control must then be performed by another device on the network, or not at all.
Example 1. Binding to a specific VSC
If deploying this scenario using an MSM720, the switch is connected to the MSM720 via port
1,2,3, or 4.
On all other controllers, the switch is connected to the controller via the LAN port and the MSM720.
