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 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: 1-120 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; Default:768)
- 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.
Web – Click Security, SSH, Settings. Enable SSH and adjust the authentication
parameters as required, then click Apply. Note that you must first generate the host
key pair on the SSH Host-Key Settings page before you can enable the SSH server.
