Use the Add Sensor Host Key dialog box to import the host keys of managed appliances into the Central Management System global host-key database. You can import keys from managed appliances and appliances that are not currently being managed by the Central Management System appliance.
Important
The key you import must start with the appliance IP address and it must not be enclosed in double quotation marks. If the key starts with the hostname, replace the hostname with the IP address.

Alternatively, you can import the key for a specific appliance as part of the connection settings. You can edit the settings of an existing managed appliance in the Edit Sensor dialog box, or import the key while you are configuring the initial connection with an appliance in the Add New Sensor dialog box. (See Adding an appliance using the Web UI and Modifying managed appliance information using the Web UI for instructions.)
Caution
If compliance mode is not enabled, global host-key authentication is optional. If you choose to use global host-key authentication, you must explicitly enable it in addition to importing the global host key. For details, see Enabling Strict and global host-key checking using the CLI .
Important
Before you perform this procedure, you must obtain the host key from the managed appliance. For appliances running Release 7.6.0 or later, you can obtain this key from the appliance Web UI or CLI. For appliances running an earlier release, you must obtain this key from the CLI. For details, see Obtaining a host key using the Web UI or Obtaining a host key using the CLI .
