Standard Key Authentication

An authentication key must be generated before the switch can accept incoming SSH2 sessions. This can be done automatically by the switch, or you can enter a previously generated key.

To have the key generated by the switch, use the following command:
configure ssh2 key

The key generation process can take up to one minute.

For the switch to use the newly generated key, the exsshd process needs to be restarted using the restart process [class cname | name {msm slot}] command with "exsshd" for name.
To use a key that has been previously created, use the following command:
configure ssh2 key {pregenerated}

The switch prompts you to enter the pregenerated key.
Note
The pregenerated key must be one that was generated by the switch. To get such a key, you can use the command show ssh2 private-key to display the key on the console. Copy the key to a text editor and remove the carriage return/line feeds. Finally, copy and paste the key into the command line. The key must be entered as one line.

The key generation process generates the SSH2 private host key. The SSH2 public host key is derived from the private host key and is automatically transmitted to the SSH2 client at the beginning of an SSH2 session.
