Management VLAN and Data VLAN Strategies

If your network includes 10 or more access points, NETGEAR recommends that you set up
at least 2 VLAN groups, a management VLAN group, and a data VLAN group. If your network
is large, you should create a number of data VLAN groups. Setting up data VLANs for clients
allows you to:
Segregate traffic by category of user
•
Set up different policies, such as access, based on the category of user
•
The following illustration shows a simplified view of how you can use VLANs to segregate
traffic by category of user.

Figure 9. Management VLAN and Data VLANs
The wireless controller uses the management VLAN to periodically 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 will reboot.
