Netgear WC7600v2 – ProSAFE Wireless Controller 사용자 설명서

UDP port 7892. Used for access point registration with the wireless controller 
after discovery.

UDP port 7893. Used for access point registration with the wireless controller 
during multicast discovery.

Enable DHCP option 43 (vendor-specific information) on the DHCP server. Specify the 
wireless controller’s IP address to allow the access points to receive the wireless 
controller’s IP address and the DHCP server to assign IP addresses to the access points.

The DHCP server on the wireless controller automatically enables DHCP option 43 with 
its own IP address.

Convert access points behind a NAT router to managed access points and then install 
them behind the NAT router.

Assign each access point an IP address. All access points that are the same model ship 

with the same default IP address. Except for access points in the factory default state that 
are in the same Layer 2 network at the remote site, if two or more access points are 
assigned the same IP address, then only one of them is discovered at a time. You must 
add the access point to the managed list, change its IP address, and then run discovery 
again to discover the next access point with that IP address.

An access point must run at least its initial firmware release or a newer version. No other 

firmware requirements exist for the access point to function with the wireless controller.

For management and monitoring purposes, make sure that you give 
remote access points at one site the same location name and that you 
create and assign meaningful building and floor names. For information 
about creating building and floor names, see 

The following limitations apply after remote access points are discovered:

Seamless Layer 2 roaming is supported for the clients of a remote access points, but 
seamless Layer 3 roaming is not supported for the clients across remote access points. 
When clients move from one IP subnet to another at the remote site, they are 
disconnected from their access point and must reconnect to another access point.

If a remote access point is disconnected from the wireless controller, for example, 
because the VPN connection goes down, the following occurs:

The remote access point uses its last known configuration and functions as a 
standalone access point while continuously attempting to reconnect to the wireless 
controller.

If the access point uses WPA-PSK, WPA2-PSK, or WPA-PSK & WPA2-PSK 
authentication, it can continue to accept new clients. If the access point uses RADIUS 
authentication with the local RADIUS server of the wireless controller instead of an 
external RADIUS server, the access point can no longer accept new clients.
