• Has 802.1x authentication
• Requires filtering rules for group filter IDs and default filter. A definition of
group filter IDs is optional. If a filter is not specified or not returned by the
Access-Accept response, the default filter group is applied.
• Has WEP and WPA privacy
• HiPath Wireless Controller is involved in authenticating users. 802.1x
packets for AAA assignment are forwarded by the Wireless AP to the
HiPath Wireless Controller through to the RADIUS server.
Traffic behavior types
There are 4 traffic types available when setting up your VNS:
• Tunneled to controller
• Bridged at AP
• Bridged to VLAN at controller
• Wireless Distribution System (WDS)
The Wireless APs are assigned to the VNS by radios. A Wireless AP radio is
available for VNS assignment until it has been assigned to a maximum eight
VNSs with the exception of WDS VNS that can handle maximum of seven VNSs.
For more information, see Section 6.17, “Wireless Distribution System”, on page
229.
The HiPath Wireless Controller can support the following:
• C2400 – Up to 64 VNSs
• C20 – Up to 8 VNSs
Once a VNS definition is saved, the HiPath Wireless Controller updates this
information on the Wireless AP. The VNS broadcasts the updates during beacon
transmission, unless the SSID beacon is suppressed on the Topology tab.
The Wireless AP Configuration page lists defined VNSs and which radio each
has been assigned to.
On the Topology tab, define parameters for DHCP for IP address assignment.
DHCP IP assignment is not applicable to Bridged at AP mode. DHCP assignment
is disabled by default for Bridged to VLAN mode. However, you can enable DHCP
server/relay functionality to have the controller service the IP addresses for the
VLAN (and wireless users).
You can also configure this VNS for management traffic or for third-party APs.
