Summit WM Series WLAN Switch and Altitude Access Point Software Version 4.1 User Guide
246
Langley Langley is a Summit WM series switch, access points, and WLAN
switch software term for the inter-process messaging infrastructure on
the Summit WM series switch.
Mobility manager (and
mobility agent)
The technique in Summit WM series switch, access points, and WLAN
switch software by which multiple Summit WM series switches on a
network can discover each other and exchange information about a
client session. This enables a wireless device user to roam seamlessly
between different Altitude APs on different Summit WM series
switches, to provide mobility to the wireless device user.
One Summit WM series switch on the network must be designated as
the mobility manager. All other Summit WM series switches are
designated as mobility agents. Relying on SLP, the mobility manager
registers with the Directory Agent and the mobility agents discover
the location of the mobility manager.
Summit WM series switch The Summit WM series switch is a rack-mountable network device
designed to be integrated into an existing wired Local Area Network
(LAN). It provides centralized control over all access points (both
Altitude APs and third-party access points) and manages the network
assignment of wireless device clients associating through access
points.
Summit spy The Summit spy is a mechanism that assists in the detection of rogue
access points. The feature has three components: (1) a radio frequency
(RF) scanning task that runs on the Altitude AP, (2) an application
called the Data Collector on the Summit WM series switch that
receives and manages the RF scan messages sent by the Altitude AP,
(3) an Analysis Engine on the Summit WM series switch that processes
the scan data.
WM-AD WM Access Domain Services (WM-AD). Extreme Networks’ means of
mapping wireless networks to the topology of an existing wired
network. When you set up WM-AD on the Summit WM series switch,
you are defining subnets for groups of wireless users. This WM-AD
definition creates a virtual IP subnet where the Summit WM series
switch acts as a default gateway for wireless devices. 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. 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 switch's
DHCP server to assign to wireless devices.
