WEC8050 / WEC8500 Operation Manual
Operator can also configure fallback to return to the original APC from the backup APC
during the service. If the fallback operation is configured, the AP periodically performs
health check to check whether the primary APC can be connected. When the connection is
required, it can immediately perform fallback according to the fallback option or can
perform fallback on a specified time. The reason why configuring fallback time zone is to
minimize the service interruption due to fallback by making it happens when the load is
low.
In an APC, operator can configure the primary and backup APCs of an AP in the following
steps.
1) Register APCs to the APC list.
In the 'APC List Management', how to add the APC list is described.
2) Add the APCs in the APC list to redundancy.
If necessary, configure the fallback function.
And then, operator can configure the APCs added to redundancy as the primary,
secondary, or tertiary server of an AP.
3) Configure a primary, secondary, and tertiary server per AP. To make an AP operate in
redundancy configuration, configure the Discovery Type of the AP as 'APC Referal'.
Use the Multi-Set function of WEC to configure several APs at the same time.
Configuration using CLI
1) By referring to the 'AP List Management', add the APC list that will be used as a
backup APC.
2) After entering into the configure  redundancy mode, add or delete the APCs in the
APC list. If necessary, configure the fallback function.
