The fields that can be configured for SSH Authentication Mode are described below:
Parameter Description
Password
This may be enabled or disabled to choose if the administrator wishes to use a
locally configured password for authentication on the Switch. This parameter is
enabled by default.
Public Key
This may be enabled or disabled to choose if the administrator wishes to use a
public key configuration set on a SSH server, for authentication. This parameter is
enabled by default.
Host-based
This 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 parameter is enabled by
default.
