To create a controller cluster, you must first define the root master controller and set an IPsec key or select a
certificate for communications between the cluster root and cluster members.
You must use the command-line interface to configure certificate authentication for cluster members. The WebUI
supports cluster authentication using IPsec keys only. If your master and local controllers use a pre-shared key for
authentication, they create the IPsec tunnel using IKEv1. If your master and local controllers use certificates for
authentication, the IPsec tunnel is created using IKEv2.
Creating a Cluster Root
Use the WebUI to identify a controller as a cluster root, and use an IPsec key to secure communication
between the cluster root and cluster members. Use the command-line interface to create a cluster root using
an IPsec key, factory-installed certificate, or custom certificate.
In the WebUI
To create a cluster root:
1. Access the WebUI of the controller you want to identify as the cluster root, and navigate to Configuration
> Controller.
2. Click the Cluster Setting tab.
3. For the cluster role, select Root.
4. In the Cluster Member IPsec Keys section, enter the controller IP address of a member controller in the
cluster. If you want to use a single key for all member controllers, use the IP address 0.0.0.0.
5. In the IPsec Key and Retype IPsec Key fields, enter the IPsec key for communication between the
specified member controller and the cluster root.
6. Click Add.
7. Optional: repeat steps 4-6 to add another member controller to the cluster.
8. Click Apply.
In the CLI
To create a cluster root, access the command-line interface of the controller you want to identify as the root of
the controller cluster, then issue one of the following commands:
l To authenticate cluster members using a custom certificate:
(host)(config) #cluster-member-custom-cert member-mac <mac> ca-cert <ca> server-cert <cert>
suite-b <gcm-128|gcm-256>]
l To authenticate cluster members using a factory-installed certificate:
(host)(config) #cluster-member-factory-cert member-mac <mac>
l To authenticate cluster members using an IPsec key:
(host)(config) #cluster-member-ip <ip-address> ipsec <key>
The <ip-address> parameter in this command is the IP address of a member controller in the cluster, and the <key>
parameter in each command is the IPsec key for communication between the specified member controller and the
cluster root. Use the IP address 0.0.0.0 in this command to set a single IPsec key for all member controllers, or
repeat this command as desired to define a different IPsec key for each cluster member.
Creating a Cluster Member
Once you have identified the cluster root, you must then identify the member controllers in the cluster.
Use the WebUI to identify a controller as a cluster member, and use an IPsec key to secure communication
between the cluster member and the cluster root. Use the command-line interface to create a cluster member
