960 CHAPTER 72: CONFIGURING SSH VERSION 2.0

Configure the authentication timeout time, number of attempts, and server key

update interval as default values.

Then, you need to run the SSH2.0-capable client software on the terminal

connected to the switch, configure the IP address of the reachable interface of the

SSH server (switch) to 192.168.0.1, configure the protocol type as SSH, and

configure the protocol version to 2. Launch the SSH connection, and enter the

username “client001” and password “aabbccddeeff” as prompted. Then, you can

enter the configuration interface of the switch.

client001@192.168.0.1’s password:

3 Configure the RSA authentication mode for the SSH user

# Configure AAA on the user interface.

[Switch] user-interface vty 1

[Switch-ui-vty1] authentication-mode scheme

# Set the remote user login protocol on the switch to SSH.

[Switch-ui-vty1] protocol inbound ssh

# Set the privilege level to 3 for the user.

[Switch-ui-vty1] user privilege level 3

[Switch-ui-vty1] quit

# Set the authentication mode to RSA for the remote user "client001" on the

switch.

[Switch] ssh user client001 authentication-type rsa

Then, you need to generate an RSA key pair (including public key and private key)

at random on the SSH2.0-capable client software, and configure the RSA public

key (the RSA public key is a PKCS-compliant hexadecimal string that is encoded by

the SSHKEY.EXE software) to the specified rsa peer-public-key on the SSH server.

# Set an RSA key on the switch.

[Switch] rsa peer-public-key Switch001
