Netgear WC7600v2 – ProSAFE Wireless Controller 사용자 설명서

The following illustration shows a simplified view of how you can use VLANs to segregate 
traffic by user category.

The wireless controller uses the management VLAN to continually exchange packets with 
the access points. For large networks, if all traffic uses a single VLAN, the client traffic could 
potentially flood the network. If flooding occurs and the wireless controller is not able to 
exchange packets with the access points, the network performance can slow down, and the 
access points can lose their connectivity with the wireless controller.

If you use the internal DHCP server of the wireless controller, deploy the wireless controller 
on a trunk port on your switch. The trunk port must provide access to all VLANs. 
To accommodate the traffic load of the trunk, use a high-speed port on your switch as the 
trunk port. If you use an external DHCP server, you do not need to deploy the wireless 
controller on a trunk port on your switch.
