Use the

 command to specify the public key of the 

server to connect with on the client, so that the client authenticates if the server is 
trustworthy.

Use the 

 command to cancel the specified 

relationship with the public key of the server.

To specify abc as the public key name of the server with IP address 192.168.0.1 on 
the client, enter the following:

[SW4500]ssh client 192.168.0.1 assign rsa-key abc

Use the 

 command to set the SSH client to 

perform the first-time authentication of the SSH server to be accessed.

Use the 

 command to cancel the first-time 

authentication.

The first-time authentication means that when the SSH client accesses the server 
for the first time in the case that there is no local copy of the server's public key, 
the user can proceed to access the server and save a local copy of the server's 
public key; when the client accesses the server next time, it uses the saved public 
key to authenticate the server.

If the first-time authentication is not supported, when there is no local copy of the 
public key of the connected server, the client assumes that the server is illegal and 
will refuse to access the server. The user can save a copy of the server's public key 
locally by other means beforehand.

By default, the client perform the first-time authentication.

To set the SSH client to perform the first-time authentication of the SSH server to 
be accessed, enter the following:
