Parameter Description
SSH Authentication Mode Settings
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.
Encryption Algorithm
3DES-CBC
Use the check box to enable or disable the Triple Data Encryption Standard encryption
algorithm with Cipher Block Chaining. The default is enabled.
Blow-fish CBC
Use the check box to enable or disable the Blowfish encryption algorithm with Cipher
Block Chaining. The default is enabled.
AES128-CBC
Use the check box to enable or disable the Advanced Encryption Standard AES128
encryption algorithm with Cipher Block Chaining. The default is enabled.
AES192-CBC
Use the check box to enable or disable the Advanced Encryption Standard AES192
encryption algorithm with Cipher Block Chaining. The default is enabled.
AES256-CBC
Use the check box to enable or disable the Advanced Encryption Standard AES-256
encryption algorithm with Cipher Block Chaining. The default is enabled.
ARC4
Use the check box to enable or disable the Arcfour encryption algorithm with Cipher
Block Chaining. The default is enabled.
Cast128-CBC
Use the check box to enable or disable the Cast128 encryption algorithm with Cipher
Block Chaining. The default is enabled.
