Authentication Algorithm 
Password 
This field may be enabled or disabled to choose if the administrator wishes to use a 
locally configured password for authentication on the Switch. This field is Enabled by 
default. 
Public Key 
This field may be enabled or disabled to choose if the administrator wishes to use a 
publickey configuration set on a SSH server, for authentication. This field is Enabled 
by default. 
Host-based 
This field may be enabled or disabled to choose if the administrator wishes to use a 
host computer for authentication. This parameter is intended for Linux users requiring 
SSH authentication techniques and the host computer is running the Linux operating 
system with a SSH program previously installed. This field is Enabled by default.
