is Enabled.<br />

Public Key Algorithm<br />

HMAC-RSA Use the pull-down to enable or disable the HMAC (Hash for Message Authentication<br />

Code) mechanism utilizing the RSA encryption algorithm. The default is Enabled.<br />

HMAC-DSA Use the pull-down to enable or disable the HMAC (Hash for Message Authentication<br />

Code) mechanism utilizing the Digital Signature Algorithm encryption. The default is<br />

Enabled.<br />

Authentication Algorithm<br />

Password This parameter may be enabled if the administrator wishes to use a locally configured<br />

password for authentication on the Switch. The default is Enabled.<br />

Public Key This parameter may be enabled if the administrator wishes to use a publickey<br />

configuration set on a SSH server, for authentication on the Switch. The default is<br />

Enabled.<br />

Host-based This parameter may be enabled if the administrator wishes to use a host computer for<br />

authentication. This parameter is intended for Linux users requiring SSH<br />

authentication techniques and the host computer is running the Linux operating<br />

system with a SSH program previously installed. The default is Enabled.<br />

Click Apply to implement changes made.<br />
