8.1
Availability overview
The HiPath Wirelesss Controller, Access Points and Convergence Software system provides
this feature to maintain service availability in the event of a HiPath Wireless Controller outage.
The availability feature links two HiPath Wireless Controllers as a pair, to share information
about their wireless APs. If one controller fails, its Wireless APs are allowed to connect to the
backup controller. The second HiPath Wireless Controller provides the wireless network and a
pre-assigned VNS for the wireless AP.
From the viewpoint of a wireless AP, if a HiPath Wireless Controller or the connection to it fails,
the wireless AP begins its discovery process. The wireless AP is directed to the appropriate
backup controller of the pair. This connection may require the wireless AP to reboot. Users on
the wireless AP must log in again and be authenticated on the second HiPath Wireless
Controller.
