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.
DHCP Server (Dynamic Host Configuration Protocol) (RFC2131) – A server
that assigns IP addresses, gateways, and subnet masks dynamically. IP
address assignment for clients can be done by the DHCP server internal to
the HiPath Wireless Controller, or by existing servers using DHCP relay. It is
also used by the Wireless APs to discover the location of the HiPath Wireless
Controller 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 Siemens solution relies on registering
“siemens” 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.
HiPath Wireless Controller, Access Points and Convergence Software relies
on the DNS for Layer 3 deployments and for static configuration of Wireless
APs. The controller can be registered in DNS, to provide DNS assisted AP
discovery. In addition, DNS can also be used for resolving RADIUS server
hostnames.
Web Authentication Server – A server that can be used for external Captive
Portal and external authentication. The HiPath Wireless Controller 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.
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 HiPath Wireless Controllers
for the following features to operate successfully:
Availability
Mobility
Mitigator for detection of rogue access points
Some features also require the definition of static routes.
