The following illustration shows a simplified view of how you can use VLANs to segregate
traffic by user category.
Management VLAN 100 Ethernet traffic
Finance VLAN 10 Ethernet traffic
Employee VLAN 20 Ethernet traffic
Deploy the wireless controller
on a trunk port if you use the
internal DHCP server

Figure 13. 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 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.
