Caution:
z If RSA authentication type is defined, then the RSA public key of the client user must
be configured on the switch.
z By default, no authentication type is specified for a new user, so they cannot access
the switch.
z For the password-publickey authentication type: SSHv1 client users can access
the switch as long as they pass one of the two authentications. SSHv2 client users
can access the switch only when they pass both the authentications.
z For the password authentication, username should be consistent with the effective
user name defined in AAA; for the RSA authentication, username is the SSH local
user name, so that there is no need to configure a local user in AAA.
IV. Configuring server SSH attributes
Configuring server SSH authentication timeout time, retry times, server keys update
interval and SSH compatible mode can effectively assure security of SSH connections
by avoiding illegal actions such as malicious password guessing.
