network
2.2.1 Components of the solution: a summary
The following is a summary checklist of the components of the Controller, Access Points and
Convergence Software solution on your enterprise network. These are described in detail in
this guide.
● The HiPath Wireless Controller, providing 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.
● The Wireless AP is a wireless LAN thin access point (IEEE 802.11) that communicates
only with a HiPath Wireless Controller.
● RADIUS Server (Remote Access Dial-In User Service) (RFC2865), or other
authentication server. Assigns and manages ID and Password protection throughout the
network. Used for authentication of the wireless users in either 802.1x or Captive Port
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).
● DHCP Server (Dynamic Host Configuration Protocol) (RFC2131). Assigns IP addresses,
gateways and subnet masks dynamically. IP address assignment for clients can be done
by the DCHP server internal to the HiPath Wireless Controller, or by existing servers using
DHCP relay. 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 are advertised by Service Agents. 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.
Offers troubleshooting
capability
Controller, Access Points and Convergence Software logs system
and session activity and provides reports to aid in troubleshooting
analysis.
Offers dynamic RF
management
Controller, Access Points and Convergence Software can
automatically select channels and adjust Radio Frequency (RF)
signal propagation power levels without user intervention.
