4. Configure the parameters as needed. The parameters are described
below:
Status
Enables or disables the feature. Choose from one of the following:
Disabled - Disables the SSH server. You must set this field to
Disabled when configuring SSH. This is the default.
Enabled - Enables the SSH server. Select this value after you have
finished configuring SSH and want to log on to the server.
Note
You cannot disable the SSH server when there is an active SSH
connection.
Host Key ID
Specifies the key ID of the encryption key pair to act as the SSH
host key. The key pair must already exist on the switch.
Server Key ID
Specifies the ID of the encryption key pair to act as the SSH server
key. The key pair must already exist on the switch.
Server Key Expiry Time
Specifies the time, in hours, for the server key to expire. This timer
determines how often the switch generates a new server key. 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 Telesyn recommends you set this
field to 1. With this setting, a new key is generated every hour.
The default is 0 hours which means the server key never expires.
The range is 0 to 5 hours.
Login Timeout
Specifies the amount of time a switch waits before releasing the
SSH server from an incomplete SSH client connection. Enter a
time in seconds. The default is 180 seconds (3 minutes). The range
is 60 to 600 seconds.
5. When you have finished setting the parameters, click Apply.
6. To permanently save the change, select the Save Config menu
selection.
