Use the ssh client first-time enable command to enable the first authentication function. 

Use the undo ssh client first-time command to disable the function. 

By default, the function is enabled. 

With first-time authentication, when an SSH client not configured with the server host public key 

accesses the server for the first time, the user can continue accessing the server, and save the host 

public key on the client. When accessing the server again, the client will use the saved server host 

public key to authenticate the server. 

Without first-time authentication, a client not configured with the server host public key will deny to 

access the server. To access the server, a user must configure in advance the server host public key 

locally and specify the public key name for authentication. 

Note that as the server may update its key pairs periodically, clients must obtain the most recent public 

keys of the server for successful authentication of the server.
