Introduction
Two Wireless LAN (WLAN) controllers are clustered together for redundancy and resiliency. As such, the cluster can only
be formed between WLAN controllers of like model. For example, a WM3600 can only be clustered with another WM3600,
not a WM3700 or WM3400.
Clustering enables redundancy for features such as AP Adoption, License Aggregation, AP failover, DHCP and AP load
balancing. Unlike previous versions of WM3000 Series software (four and below), clustering now truly uses a single
configuration across cluster members (not including device specific items). The configuration of the cluster or adopted AP
can be modified through the GUI of either cluster member. AP and AAP licenses are shared across the cluster. However
the advanced Security and Advanced WIPS licenses will need to be installed per WLAN controller.
Three scenarios will be explored in this document to build a cluster.
•The first will put two WLAN controllers in the same Layer-2 network. The cluster is built with a mix of CLI
(command line interface) commands and GUI modifications.
•The second scenario captures how to configure the cluster strictly through the CLI on both WLAN controllers,
but still in a Layer-2 network.
•The third configuration leverages the CLI again, but the controllers will reside in unique VLANS (L3 topology).

•Copy the running configuration from WM3600-1 and it load into WM3600-2
•Reboot WM3600-2
•Confirm Cluster
L2 Topology – CLI Only
•Set Management IP address, VLAN, and Cluster information for WM3600-1
•Add WM3600-2 as a device to WM3600-1
•Set Management IP address, VLAN and Cluster information for WM3600-2
•Add WM3600-1 as a device to WM3600-2
•Confirm Cluster
L3 Topology – CLI Only
•Set Management IP address, VLAN and Cluster information for WM3600-1
•Add WM3600-2 as a device to WM3600-1
•Set Management IP address, VLAN and Cluster information for WM3600-2
•Add WM3600-1 as a device to WM3600-2
•Confirm Cluster
AP Adoption and Failover Testing
•Disable Port 38 in Switch2
•Plug in all APs
•APs adopt to the Cluster
•Enable port 38 on Switch2
•Reboot WM3600-1
•Ensure all APs failover to WM3600-2

Manual Set-up (CLI & GUI) – L2 topology
A cluster will be built of two WM3600s. The configuration file from WM3600-1 is copied across to WM3600-2 and it is
rebooted into the same configuration that WM3600-1 is running. This will establish the cluster.
Once again, the procedure will use both the GUI and CLI.
MGMT IP Address
1. Assign an IP address to the management interface (me1) on WM3600-1.
2. Assign an IP address to the management interface (me1) on WM3600-2.
3. Determine the Base Ethernet MAC address of WM3600-2 controller with the command: show version.

Set Country Code
1. Login to WM3600-1 using a web browser (https://172.16.0.1)
2. Set the Country Code for the cluster. In this example it is set to US. Click Configuration > RF Domains>
Default > Edit.
