◆ Default Gateway — The default gateway is the IP address of the
router for the access point, which is used if the requested destination
address is not on the local subnet.
If you have management stations, DNS, RADIUS, or other network
servers located on another subnet, type the IP address of the default
gateway router in the text field provided.
◆ Primary and Secondary DNS Address — The IP address of Domain
Name Servers on the network. A DNS maps numerical IP addresses to
domain names and can be used to identify network hosts by familiar
names instead of the IP addresses.
If you have one or more DNS servers located on the local network, type
the IP addresses in the text fields provided.
After you have network access to the access point, you can use the web
browser interface to modify the initial IP configuration, if needed.
If there is no DHCP server on your network, or DHCP fails, the access point
will automatically start up with a default IP address of 192.168.1.1
RADIUS SETTINGS
Remote Authentication Dial-in User Service (RADIUS) is an authentication
protocol that uses software running on a central server to control access to
RADIUS-aware devices on the network. An authentication server contains a
database of user credentials for each user that requires access to the
network.
PRIMARY AND
SECONDARY RADIUS
S
ERVER SETUP
A primary RADIUS server must be specified for the access point to
implement IEEE 802.1X network access control and Wi-Fi Protected Access
(WPA) wireless security. A secondary RADIUS server may also be specified
as a backup should the primary server fail or become inaccessible.
In addition, you can configure a RADIUS Accounting server to receive user-
session accounting information from the access point. RADIUS Accounting
can be used to provide valuable information on user activity in the
network.
This guide assumes that you have already configured RADIUS server(s) to
support the access point. Configuration of RADIUS server software is
beyond the scope of this guide, refer to the documentation provided with
the RADIUS server software.
