  • Page 31: Stacked Controller Configuration

    Management VLAN and Data VLAN Strategies If your network includes 10 or more access points, NETGEAR recommends that you set up at least two 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: •...
  • Page 32 ProSafe 20-AP Wireless Controller WC7520 Figure 10. 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.
