Summit Wm Controller, Access Points And Software And Your Network - Extreme Networks Summit WM20 User Manual

Overview of the Summit WM Controller, Access Points and Software Solution
Integrates with existing network – A Summit WM Controller can be added to an existing enterprise
●
network as a new network device, greatly enhancing its capability without interfering with existing
functionality. Integration of the Summit WM Controllers and Wireless APs does not require any
reconfiguration of the existing infrastructure (for example, VLANs).
Offers centralized management and control – An administrator accesses the Summit WM Controller
●
in its centralized location to monitor and administer the entire wireless network. From the Summit
WM Controller, the administrator can recognize, configure, and manage the Wireless APs and
distribute new software releases.
Provides easy deployment of Wireless APs – The initial configuration of the Wireless APs on the
●
centralized Summit WM Controller can be done with an automatic "discovery" technique. For more
information, see
Provides security via user authentication – Uses existing authentication (AAA) servers to
●
authenticate and authorize users.
Provides security via filters and privileges – Uses virtual networking techniques to create separate
●
virtual networks with defined authentication and billing services, access policies, and privileges.
Supports seamless mobility and roaming – Supports seamless roaming of a wireless device from
●
one Wireless AP to another on the same Summit WM Controller.
Integrates third-party access points – Uses a combination of network routing and authentication
●
techniques.
Prevents rogue devices – Unauthorized access points are detected and identified as harmless or
●
dangerous rogue APs.
Provides accounting services – Logs wireless user sessions, user group activity, and other activity
●
reporting, enabling the generation of consolidated billing records.
Offers troubleshooting capability – Logs system and session activity and provides reports to aid in
●
troubleshooting analysis.
Offers Dynamic Radio Management – Automatically selects channels and adjusts Radio Frequency
●
(RF) signal propagation and power levels without user intervention.
Summit WM Controller, Access Points and Software
and Your Network
This section is a summary of the components of the Summit WM Controller, Access Points and
Software solution on your enterprise network. The following are described in detail in this guide, unless
otherwise stated:
Summit WM Controller – A rack-mountable network device that provides centralized control over
●
all access points (both Wireless APs and third-party access points) and manages the network
assignment of wireless device clients associating through access points.
Wireless AP – A wireless LAN fit access point (IEEE 802.11) that communicates only with a Summit
●
WM Controller.
RADIUS Server (Remote Access Dial-In User Service) (RFC2865), or other authentication server –
●
An authentication server that assigns and manages ID and Password protection throughout the
network. Used for authentication of the wireless users in either 802.1x or Captive Portal security
modes. The RADIUS Server system can be set up for certain standard attributes, such as filter ID,
and for the Vendor Specific Attributes (VSAs). In addition, Radius Disconnect (RFC3576) which
permits dynamic adjustment of user policy (user disconnect) is supported.
