TCP Port Number
(1-65535)
Specifies the TCP port used to communication between SSH client and server. The default
value is
22 .
Rekey Timeout
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 .

SSH Authmode and Algorithm Settings
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 checking the boxes. All algorithms are enabled by default.

The following algorithms may be set:
Parameter Description
SSH Authentication Mode Settings
Password
This parameter may be enabled if the administrator wishes to 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 use a public key configuration
set on a SSH server, for authentication on the Switch. The default is enabled.
Host-based
This parameter may be enabled 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. The default is enabled.
Encryption Algorithm
3DES-CBC
Check the box to enable the Triple Data Encryption Standard encryption algorithm with
Cipher Block Chaining. The default is enabled.
Blow-fish CBC
Check the box to enable the Blowfish encryption algorithm with Cipher Block Chaining. The
default is enabled.
AES128-CBC
Check the box to enable the Advanced Encryption Standard AES128 encryption algorithm
with Cipher Block Chaining. The default is enabled.
AES192-CBC
Check the box to enable the Advanced Encryption Standard AES192 encryption algorithm
with Cipher Block Chaining. The default is enabled.
