Configuring the SSH Server

USER AUTHENTICATION

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.

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 via either SSH 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)
