Asanté IntraCore 36000 Series 

CLI 

This example generates a host-key pair using both the RSA and DSA algorithms, stores the keys to flash 
memory, and then displays the host’s public keys. 

Console#

ip ssh crypto host-key generate 

 

Console#

ip ssh save host-key

 

Console#

6.4.3 Configuring the SSH Server 

The SSH server includes basic settings for authentication.  

Field Attributes 

SSH Server Status – Allows you to enable/disable the SSH server on the switch. (Default: Disabled) 

Version – The Secure Shell version number. Version 2.0 is displayed, but the switch supports management 
access through SSH either Version 1.5 or 2.0 clients. 

SSH Authentication Timeout – Specifies the time interval in seconds that the SSH server waits for a 
response from a client during an authentication attempt. 

(Range: 1 to 120 seconds; Default: 120 seconds) 

SSH Authentication Retries – Specifies the number of authentication attempts that a client is allowed before 
authentication fails and the client has to restart the authentication process. (Range: 1-5 times; Default: 3) 

SSH Server-Key Size – Specifies the SSH server key size. (Range: 512-896 bits) 

•

 

The server key is a private key that is never shared outside the switch. 

•

 

The host key is shared with the SSH client, and is fixed at 1024 bits.
