Network assignment and authentication for a WM-AD
Summit WM-Series WLAN Switch and Altitude Access Point Software Version 1.0 User Guide
63
The key choice for a WM-AD is the type of network assignment, which determines all the other factors
of the WM-AD. There are two options for network assignment:
SSID:
has Captive Portal authentication, or no authentication.
requires restricted filtering rules before authentication and, after authentication, filtering rules for
group Filter IDs.
is used for a WM-AD supporting wireless voice traffic (QoS).
is used for a WM-AD supporting third-party APs.
has WEP and WPA-PSK privacy.
AAA (Authentication, Authorization and Accounting)
has 802.1x authentication
requires filtering rules for group Filter IDs and default filter.
has WEP and WPA privacy.
In the Topology screen, you assign the available Altitude APs (by radio) to the WM-AD. An Altitude AP
radio will appear in the list as available for WM-AD assignment until it has been assigned to four WM-
ADs. After that, it will no longer appear in the list.
After a WM-AD definition has been saved, the Summit WM-Series Switch updates this information on
the Altitude AP. Each radio acquires up to four SSIDs (one for each WM-AD it is part of), and
broadcasts these during beacon transmission (unless the SSID beacon is suppressed in the Topology
screen).
You can view (in the Altitude AP Configuration screen) a list of defined WM-ADs to which each radio has
been assigned.
In the To po log y area of WM Access Domain Configuration, you also define other aspects of the WM-AD,
such as the parameters for DHCP for IP address assignment. You might also configure this WM-AD for
management traffic only, or for Third-Party Access Points, or for Voice Traffic. (These are described in
detail later in this Guide.)
Network assignment and authentication for a WM-AD
The second step is to configure the authentication mechanism for the WM-AD. The authentication
mechanism depends on the network assignment. In addition, all WM-AD definitions can include
authentication by MAC address.
Authentication with SSID network assignment
If SSID was selected, there are two authentication options:
None: The wireless device connects to the network, but can only access specified network
destinations (defined in the Non-Authenticated Filter). No authentication is performed.
Captive Portal: The wireless device connects to the network, but can only access specified network
destinations (defined in the Non-Authenticated Filter). One of those destinations is a web page logon
screen (the portal in which he is captive), where the user must input an ID and a password. This
