Import Client’s Public Key to the Switch – Use the
copy tftp
public-key
command
to copy a file containing the public key for all the
SSH client’s granted management access to the switch. (Note that these
clients must be configured locally on the switch with the username
command as described on page 4-34.) The clients are subsequently
authenticated using these keys. The current firmware only accepts
public key files based on standard UNIX format as shown in the
following example for an RSA Version 1 key:

4.
Set the Optional Parameters – Set other optional parameters, including
the authentication timeout, the number of retries, and the server key
size.
5.
Enable SSH Service – Use the
ip ssh server
command to enable the
SSH server on the switch.
6.
Configure Challenge-Response Authentication – When an SSH client
attempts to contact the switch, the SSH server uses the host key pair to
negotiate a session key and encryption method. Only clients that have a
private key corresponding to the public keys stored on the switch can
gain access. The following exchanges take place during this process:
a.
The client sends its public key to the switch.
b.
The switch compares the client's public key to those stored in
memory.
c.
If a match is found, the switch uses the public key to encrypt a
random sequence of bytes, and sends this string to the client.
