Summit WM series switch, access points, and WLAN switch software and your network

during the initial registration process. For SLP, DHCP should have Option 78 enabled. Option 78
specifies the location of one or more SLP Directory Agents.
Service Location Protocol (SLP) (SLP RFC2608) – Client applications are User Agents and services
that are advertised by a Service Agent. In larger installations, a Directory Agent collects information
from Service Agents and creates a central repository. The Extreme Networks solution relies on
registering “extreme” as an SLP Service Agent.
Domain Name Server (DNS) A server used as an alternate mechanism (if present on the
enterprise network) for the automatic discovery process. Summit WM series switch, access points,
and WLAN switch software relies on the DNS for Layer 3 deployments and for static configuration
of Altitude APs. The controller can be registered in DNS, to provide DNS assisted AP discovery.
Web Authentication Server – A server that can be used for external Captive Portal and external
authentication. The Summit WM series switch has an internal Captive portal presentation page,
which allows Web authentication (Web redirection) to take place without the need for an external
Captive Portal server.
RADIUS Accounting Server (Remote Access Dial-In User Service) (RFC2866) – A server that is
required if RADIUS Accounting is enabled.
Simple Network Management Protocol (SNMP) – A Manager Server that is required if forwarding
SNMP messages is enabled.
Check Point Server (Check Point Event Logging API) – A server for security event logging that is
required if a firewall application is enabled. Checkpoint ELA certification for OPSEC is provided.
Network infrastructure – The Ethernet switches and routers must be configured to allow routing
between the various services noted above. Routing must also be enabled between multiple Summit
WM series switches for the following features to operate successfully:
Availability
Mobility
Summit spy for detection of rogue access points
Some features also require the definition of static routes.
Web Browser – A browser provides access to the Summit WM series switch Management user
interface to configure the Summit WM series switch, access points, and WLAN switch software.
SSH Enabled Device A device that supports Secure Shell (SSH) is used for remote (IP) shell access
to the system.
Zone Integrity – The Zone integrity server enhances network security by ensuring clients accessing
your network are compliant with your security policies before gaining access. Zone Integrity Release
5 is supported.
Network traffic flow
Figure 3 illustrates a simple configuration with a single Summit WM series switch and two Altitude
APs, each supporting a wireless device. A RADIUS server on the network provides authentication, and
a DHCP server is used by the Altitude APs to discover the location of the Summit WM series switch
during the initial registration process. Network inter-connectivity is provided by the infrastructure
routing and switching devices.
