Configuring the switch as an SSH server SSH server configuration task list Task Generating DSA or RSA key pairs Enabling the SSH server function Configuring the user interfaces for SSH clients Configuring a client public key Configuring an SSH user Setting the SSH management parameters Setting the DSCP value for packets sent by the SSH server Remarks Required Required Required Required for publickey authentication users and optional for password authentication users Optional Optional Optional Generating DSA or RSA key pairs In the key and algorithm negotiation stage, the DSA or RSA key pairs are used to generate the session key and session ID and for the client to authenticate the server. Configuration guidelines • To support SSH clients that use different types of key pairs, generate both DSA and RSA key pairs on the SSH server. • The public-key local create rsa command generates a server RSA key pair and a host RSA key pair. Each of the key pairs consists of a public key and a private key. The public key in the server key pair of the SSH server is used in SSH1 to encrypt the session key for secure transmission of the key. As SSH2.0 uses the DH algorithm to generate the session key on the SSH server and client, no session key transmission is required in SSH2.0 and the server key pair is not used. 180
