Note
You cannot create encryption keys from the web browser interface,
but you can from the menus and command line interfaces.
Server Key ID
Specifies the ID number of the encryption key for the SSH server. The
key must already exist on the switch. The default is Not Defined.
Server Expiry Time
Sets the time, in hours, for a server key to expire. This timer
determines how often a server key is regenerated for security
purposes. A server key is only valid for the time period configured in
the Server Key Expiry (Expiration) Time timer. Allied Telesis
recommends setting this field to 1 to regenerate the key every hour.
Login Timeout
Specifies the time in seconds it takes to release the SSH server from
an incomplete SSH client connection. The default is 180 seconds (3
minutes). The range is 60 to 600 seconds.
