Use the Sensor Management page to configure authentication parameters for the remote user the Central Management System appliance uses to log in to an appliance to establish the connection. This is an existing "admin" user on the managed appliance.
When you add an appliance using the Web UI, you must configure a username and password, so the Central Management System appliance initially uses password authentication. After the appliance is connected, you can select an SSH-DSA2 or SSH-RSA2 key, which changes the authentication type accordingly.
Important
After you configure SSH-DSA2 or SSH-RSA2 authentication, the only way to return to password authentication using the Web UI is to delete the appliance and then add it again.

In the Action column for the appliance, click Use CMS Public Key to Connect. The Password field is replaced by the CMS Public Key field.
Click the Select a Key drop-down list.
To configure SSH-DSA2 authentication, do one of the following:
Select an existing key.
Select No dsa keys. Create One, and then select the dsa-admin key that is created.
To configure SSH-RSA2 authentication, do one of the following:
Select an existing key.
Select No rsa keys. Create one, and then select the rsa-admin key that is created.
Click Update Sensor.
Note
The connection will be interrupted briefly. Error messages and indicators will be displayed, but they will clear as soon as the connection is reestablished.
Verify that the key is displayed in the Public Key Used column for the appliance.
