7. 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.
8. If you are not synchronizing topology definitions, the availability wizard completes the
configuration.
9. Click Close.
This operation marks the desired topologies 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.
All these configurable elements have a Synchronize check box (on their main/general
configuration tab) that allows for individual control and selection of availability from the main
element configuration page.
Configuring Availability Manually
When configuring availability manually, you configure each SCALANCE IWLAN Controller
separately.
1. On the SCALANCE IWLAN Controller Configuration Availability screen, set up the
SCALANCE IWLAN Controller in Paired Mode.
2. On the VNS configuration window, define a VNS (through topology, WLAN service, policy
and VNS configuration) on each SCALANCE IWLAN Controller with the same SSID. The IP
addresses must be unique. For more information, see “Manually Creating a VNS” on
page 7-21. A SCALANCE IWLAN 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.
3. On both SCALANCE IWLAN Controllers, on the Wireless AP Registration screen, select the
Security Mode Allow only approved Wireless APs to connect option so that no more Wireless
APs can register unless they are approved by the administrator.
4. On each SCALANCE IWLAN Controller, on the Wireless AP configuration Access Approval
screen, check the status of the Wireless APs and approve any APs that should be connected to
that controller.
System AP defaults can be used to assign a group of VNSs to the foreign APs:
– If the APs are not yet known to the system, the AP will be initially configured according to
AP default settings. To ensure better transition in availability, Siemens recommends that
the AP default settings match the desired assignment for failover APs.
