SSH Authmode and Algorithm Settings
The SSH Algorithm window allows the configuration of the desired types of SS H algorithms used for authentica tion
encryption. There are four categories of algorithms listed and specific algorithm s of each may be enab led or disabled
by checking the boxes. All algorithms are enabled by default.
To view this window, click Security > SSH > SSH Authmode and Algorithm Settings as shown below:
Figure 5 - 32 SSH Authmode and Algorithm Settings window
The following algorithms may be set:
Parameter Description
SSH Authentication Mode Settings
Password This parameter may be enabled if the administrator wishes t o use a locally configured
password for authentication on the Switch. The default is enabled.
Public Key This parameter may be enabled if the administrator wishes to us e a publ ic k ey conf igurat ion
set on a SSH server, for authentication on the Switch. The default is enabl ed.
Host-based This parameter may be enabled if the administrator wishes to us e a host computer for
authentication. This parameter is intended for Linux users req uiring SSH authentication
techniques and the host computer is running the Linux operating s ystem with a SSH
program previously installed. The default is enabled.
Encryption Algorithm
3DES-CBC Check the box to enable the Triple Data Encryption Standard e ncryption algorithm with
Cipher Block Chaining. The default is enabled.
Blow-fish CBC Check the box to enable the Blowfish encryption algorithm with Cipher Block Cha ining. The
default is enabled.
AES128-CBC Check the box to enable the Advanced Encryption Standard AES128 encrypti on algorithm
with Cipher Block Chaining. The default is enabled.
AES192-CBC Check the box to enable the Advanced Encryption Standard AES192 encrypti on algorithm
with Cipher Block Chaining. The default is enabled.
AES256-CBC Check the box to enable the Advanced Encryption Standard AES-25 6 encryption algor ithm
with Cipher Block Chaining. The default is enabled.
ARC4 Check the box to enable the Arcfour encryption algorithm with Cipher Block Chaining. The
default is enabled.
