ProSAFE Wireless Controller WC9500
The following illustration shows a simplified view of how you can use VLANs to segregate
traffic by user category:
Figure 8. Example: Use VLANs to segregate traffic by user categories
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 this happens, and the wireless controller is not able to
exchange packets with the access points, it can cause network performance to 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, you should deploy the wireless
controller on a trunk port on your switch.
The trunk port should have access to all VLANs.
Use a high-speed port on your switch as the trunk port to accommodate the traffic load of the
trunk. If you use an external DHCP server
, you do not need to deploy the wireless controller
on a trunk port on your switch.
