How to configure the AC cluster of EWS4502 ?
The EWS4502 with highest priority in the same cluster becomes the Cluster Controller.
If the priority is the same, the switch with lowest IP address will be the Cluster Controller.
And the highest cluster priority is 255.
AC cluster Scenario
How to configure the cluster priorty ?
Manage Page: System -> WLAN -> WLAN Configuration -> Global
1. Configure the cluster priority of EWS4502-1 192.168.1.30 to 255.
*The highest cluster priority is 255, thus EWS4502-1 will become the Cluster Controller.
2. Configure the cluster priority of EWS4502-2 192.168.1.31 to 1.
How to check and ensure the cluster priority applied ?
Manage Page: System -> WLAN -> Status/Statistics -> Peer Switch
Users can know which AC is the current cluster controller and which AC will manage AP.
1. Peer switch status of Cluster Controller EWS4502-1 192.168.1.30.
2. Peer switches status of slave AC ECW4502-2 192.168.1.31.
*By default, AP will be managed by AC Controller first.
Troubleshooting
Q: Why Cluster Controller and Slave AC displayed the same AP ?
Manage Page: System -> WLAN -> Status/Statistics -> Managed AP
A: The Cluster Controller collects status and statistics from all the other AC in the cluster, including information about the APs peer switches manage and the clients associated to those APs.
Thus if the AP managed by Slave AC then the user will see this situation.
*By default, AP will be managed by AC Controller first.
Q: What kind of situation the AP will be managed by Slave AC ?
A: The users configure the AP to find the Slave AC to manage first.
For Example:
Users specify the IP address of AC manually.
AP obtains the IP address of AC from the DHCP server. (Option 43)
