Configuring the SSH Server to Be 
Compatible with SSH1 Clients

Exporting the RSA or DSA Public Key 
Optional 
If a client does not support first-time

the server’s public key and configure 
the key on the client. 
 
 
The SSH server needs to cooperate with an SSH client to complete the interactions between them. For 
SSH client configuration, refer to 
Configuring the SSH Client. 
 
Configuring the User Interfaces for SSH Clients 
An SSH client accesses the device through a VTY user interface. Therefore, you need to configure the 
user interfaces for SSH clients to allow SSH login. Note that the configuration takes effect at the next 
login.
