WM Access Domain Services
WM Access Domain Services (WM-AD) provide a versatile method of mapping wireless networks to
the topology of an existing wired network.
When you set up WM Access Domain Services (WM-AD) on the Summit WM series switch you are
defining subnets for groups of wireless users. The WM-AD definition provides the binding between
WM-AD IP topology configuration (Routing, DHCP policy) and the RF configuration parameters that
advertise and control network access (SSID, Privacy policy: WEP and WPA). This technique enables
policies and authentication to be applied to the groups of wireless users on a WM-AD, as well as the
collecting of accounting information on user sessions that can be used for billing.
When a WM-AD is set up on the Summit WM series switch:
One or more Altitude APs (by radio) are associated with it
A range of IP addresses is set aside for the Summit WM series switchs DHCP server to assign to
wireless devices
If routing protocol is enabled, the Summit WM series switch advertises the WM-AD as a routable
network segment to the wired network and routes traffic between the wireless devices and the wired
network. The Summit WM series switch WM200/2000 also supports VLAN-bridged assignment for
WM-ADs. This allows the controller to directly bridge the set of wireless devices associated with a WM-
AD directly to a specified core VLAN. The Summit WM series switch WM200/2000 can support up to
64 WM-ADs.
The AP radios can be assigned to each of the configured WM-ADs in a system. Each AP can be the
subject of 8 WM-AD assignments (corresponding to the number of SSIDs it can support). Once a radio
has all 8 slots assigned, it is no longer eligible for further assignment.
Static routing and routing protocols
Routing can be used on the Summit WM series switch to support the WM-AD definitions. Through the
user interface you can configure routing on the Summit WM series switch to use one of the following
routing techniques:
Static routes Use static routes to set the default route of a Summit WM series switch so that
legitimate wireless device traffic can be forwarded to the default gateway.
Open Shortest Path First (OSPF, version 2) (RFC2328) – Use OSPF to allow the Summit WM series
switch to participate in dynamic route selection. OSPF is a protocol designed for medium and large
IP networks with the ability to segment routes into different areas by routing information
summarization and propagation. Static Route definition and OSPF dynamic learning can be
combined, but a static route definition will take precedence over dynamic rules.
Next-hop routing – Use next-hop routing to specify a unique gateway to which traffic on a WM-AD
is forwarded. Defining a next-hop for a WM-AD forces all the traffic in the WM-AD to be forwarded
to the indicated network device, bypassing any routing definitions of the controller's route table.
Packet filtering policy
Policy refers to the rules that allow different groups of users access to the network. The Summit WM
series switch, access points, and WLAN switch software system can link authorized users to user
groups. These user groups then can be confined to predefined portions of the network.
