If you are synchronizing topology definitions, the Topology Definitions
screen is displayed. Do the following:
a) In the Synchronization Settings section, complete the topology
properties that are missing. Any topology that did not already exist on
the peer controller will have missing properties on the Topology
Definitions screen.
The fields configured are actual parameter values that are configured
at the remote Controller with respect to associated topologies chosen
for synchronization. Some of these parameters are: Interface IP
address, Netmask, L2 port, VLAN ID, DHCP range, etc.
b) Click Finish.
If you are not synchronizing topology definitions, the availability wizard
completes the configuration.
7. Click Close.
This operation will mark the desired topologies as desired for synchronization.
The two controllers exchange information and the configuration is applied to the
remote controller.
On the local controller, the "Enable Synchronization of System Configuration"
becomes selected. This can be double checked by navigating to VNS
Configuration, Global and then Sync Summary. This tab also lists all Topologies,
Policies, WLAN Services and VNSes with their synchronization status (on or off).
The Sync status for any of these elements can also be changed from this tab.
Moreover, all these configurable elements have a check box called "synchronize"
(on their main/general configuration tab) that would allow for individual control
and selection of availability from the main element configuration page.
7.3 Configuring availability manually
When configuring availability manually, you configure each HiPath Wireless
Controller separately. One method is as follows:
1. On the HiPath Wireless Controller Configuration Availability screen, set up
the HiPath Wireless Controller in Paired Mode.
2. On the VNS configuration window, define a VNS (through topology, WLAN
service, policy and VNS configuration) on each HiPath Wireless Controller
with the same SSID. The IP addresses must be unique. For more information,
see Section 6.8, “Configuring a Topology”, on page 296. A HiPath Wireless
Controller VLAN Bridged topology can permit two controllers to share the
same subnet. This setup provides support for mobility users in a VLAN
Bridged VNS.
