ProSAFE Wireless Controller WC7600 Access Point Discovery Guidelines You must run the Discovery Wizard for the wireless controller to discover supported NETGEAR access points on the LAN or WAN. The wireless controller can discover access points that are still in their factory default state and access points that are already deployed in a standalone configuration. Both access points in factory default state and deployed standalone access points run standalone firmware. For information about the minimum required standalone firmware versions, see NETGEAR ProSAFE Access Points on page 16. After the access points are discovered, you can add them to the Managed AP List, enabling the wireless controller to automatically upgrade the standalone firmware of the access points to managed-mode firmware. You can then use the wireless controller to configure, manage, and monitor the managed access points. General Discovery Guidelines An access point must run at least its initial firmware release or a newer version. For firmware requirements, see NETGEAR ProSAFE Access Points on page 16. No other firmware requirements exist for the access point to function with the wireless controller. Access points in factory default state that are in the same Layer 2 network can have the same IP address and still be discovered. Depending on the configuration of the DHCP server, these access points are discovered in parallel or sequentially. DHCP option 43 (vendor-specific information) must be enabled on an external DHCP server. Specifying an internal DHCP server on the wireless controller automatically enables DHCP option 43 with the IP address of the wireless controller. Layer 3 Discovery Guidelines The following are the requirements for autodiscovery of local access points across Layer 3 networks: • All standalone access points must have SNMP and SSH enabled. (This is the default setting for access points.) • UDP port number 7890 must be unblocked in the firewall. • Each access point must have a unique IP address. (This requirement does not apply to Layer 2 discovery.) If more than one access point has the same IP address, only one of them is discovered at a time. You must add the access point to the managed list, change its IP address, and run discovery again to discover the next access point with that IP address. • DHCP option 43 (vendor-specific information) must be enabled on an external DHCP server. Specifying an internal DHCP server on the wireless controller automatically enables DHCP option 43 with the IP address of the wireless controller. Discover and Manage Access Points 120
