ProSafe 20-AP Wireless Controller WC7520 Reference Manual After the survey is complete, use the collected data to set up an RF plan. For more information, see RF Planning Overview on page 36. Before You Configure a Wireless Controller These sections assume that you have deployed at least one wireless controller in your network and are ready to configure the wireless controller. For information about how to deploy the wireless controller in your network, see the WC7520 ProSafe Wireless Controller Installation Guide at http://kb.netgear.com/app/products/model/a_id/13060. For many configurations, you can use the wireless default settings. The IP address, VLAN, DHCP server, client authentication and data encryption settings are specific to your environment. Following are short sections that discuss these settings (with the exception of IP address settings, which are self explanatory). For information about how to configure these settings, see the links to the chapters. VLANs Management VLAN The management VLAN is the dedicated VLAN for access to the wireless controller. All traffic that is directed to the wireless controller, including HTTP, HTTPS, SNMP, and SSH traffic, is carried over the management VLAN. If the management VLAN is also configured as a tagged VLAN (the most common configuration), the packets to and from the wireless controller carry the 802.1Q VLAN header with the assigned VLAN number. If the management VLAN is marked as untagged, the packets that are sent from the wireless controller do not carry the 802.1Q header, and all untagged packets that are sent to the wireless controller are treated as management VLAN traffic. Note: Use a tagged VLAN or change the tagged VLAN ID only if the hubs and switches on your LAN support 802.1Q. If they do not, and you have not specifically configured a tagged VLAN with the same VLAN ID on the hubs and switches in your network, IP connectivity might be lost. The wireless controller must have IP connectivity with the access points through the management VLAN. If the wireless controller and the access points are on different management VLANs, external VLAN routing must allow IP connectivity between the wireless controller and the access points. For information about how to configure management VLANs, see Configuring IP and VLAN Settings on page 57. Chapter 2: System Planning and Deployment Scenarios | 23
