To add a FortiClient license to each cluster unit

Normally you would add FortiClient licenses to the FortiGate units before forming the cluster. However, you can can use the following steps to add FortiClient licenses to an operating cluster.

Contact your reseller to purchase FortiClient licenses for your cluster units. Each cluster unit must have its own FortiClient license.

When you receive the license keys you can log into https://support.fortinet.com and add a FortiClient license key to each licensed FortiGate unit. Then, as long as the cluster can connect to the Internet the license keys are downloaded from the FortiGuard network to all of the FortiGate units in the cluster.

You can also use the following steps to manually add the license keys to your cluster units from the CLI. Your cluster must be connected to the Internet.

1. Log into the CLI of each cluster unit using its reserved management interface IP address.

2. Enter the following command to the unit’s serial number:

get system status

3. Enter the following command to add the license key for that serial number:

execute FortiClient-NAC update-registration-license <license-key>

4. Confirm that the license has been installed and the correct number of FortiClients are licensed.

execute forticlient info

Maximum FortiClient connections: unlimited. Licensed connections: 114

NAC: 114

WANOPT: 0

Test: 0

Other connections: IPsec: 0

SSLVPN: 0

5. Repeat for all of the cluster units.

You can also log into the primary unit CLI and use the execute ha manage command to connect to each cluster unit CLI.
