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.
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.
• 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.
• 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 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.
• Web Browser – A browser provides access to the HiPath Wireless Controller
Management user interface to configure the Controller, Access Points and
Convergence Software.
• SSH Enabled Device – A device that supports Secure Shell (SSH) is used
for remote (IP) shell access to the system.
