Add More Cluster Nodes

Add or replace the Firewall Threat Defense cluster node in an existing cluster. When you add a new cluster node in FXOS, the Firewall Management Center adds the node automatically.

Note

The FXOS steps in this procedure only apply to adding a new chassis; if you are adding a new module to a Firepower 9300 where clustering is already enabled, the module will be added automatically.

Before you begin

  • In the case of a replacement, you must delete the old cluster node from the Firewall Management Center. When you replace it with a new node, it is considered to be a new device on the Firewall Management Center.

  • The interface configuration must be the same on the new chassis. You can export and import FXOS chassis configuration to make this process easier.
