SSH Algorithm

The SSH Algorithm window allows the configuration of the desired types of SSH algorithms used for authentication encryption.
There are four categories of algorithms listed and specific algorithms of each may be enabled or disabled by using their
corresponding pull-down menus. All algorithms are enabled by default. To open the following window, click Security
Management > Secure Shell (SSH) > SSH Algorithm:
The following algorithms may be set:
Parameter
3DES-CBC
Blow-fish CBC
AES128-CBC
Allows the Administrator to set the maximum number of attempts that a user may try to log on
to the SSH Server utilizing the SSH authentication. After the maximum number of attempts has
been exceeded, the Switch will be disconnected and the user must reconnect to the Switch to
attempt another login. The number of maximum attempts may be set between 2 and 20. The
default setting is 2.
Using the pull-down menu uses this field to set the time period that the Switch will change the
security shell encryptions. The available options are Never, 10 min, 30 min, and 60 min. The
default setting is Never.
