Adding FortiClient licenses to cluster units with no reserved management interface
If you have not set up reserved management IP addresses for your cluster units, you can still add FortiClient license keys to each cluster unit. You must log into the primary unit and then use the execute ha manage command to connect to each cluster unit CLI. For example, use the following steps to add a FortiClient license key a cluster of three FortiGate units:
1. Log into the primary unit CLI and enter the following command to confirm the serial number of the primary unit:
get system status
2. Add the FortiClient license key for that serial number to the primary unit:
execute FortiClient-NAC update-registration-license <license-key>
You can also use the web‑based manager to add the license key to the primary unit.
3. Enter the following command to log into the first subordinate unit:
execute ha manage 1
4. Enter the following command to confirm the serial number of the cluster unit that you have logged into:
get system status
5. Add the FortiClient license key for that serial number to the cluster unit:
execute FortiClient-NAC update-registration-license <license-key>
6. Enter the following command to log into the second subordinate unit:
execute ha manage 2
7. Enter the following command to confirm the serial number of the cluster unit that you have logged into:
get system status
8. Add the FortiClient license key for that serial number to the cluster unit:
execute FortiClient-NAC update-registration-license <license-key>
