Examples To configure a user for public key authentication:
switch:admin>

To set up SSH public key authentication on a switch for incoming connections:
1. Generate a private/public key pair on a remote host (accept default directory and file name):
2. Import the public key from the remote host to the local switch:
Fabric OS Command Reference

genkey prompts for user input on the following parameters:
passphrase
Accepts a string of arbitrary length. This operand is optional, but creating a
pass-phrase is strongly recommended. Good pass phrases are 10-30
characters long, are not simple sentences or otherwise easily guessable and
contain a mix of upper and lowercase letters, numbers, and
nonalphanumeric characters. There is no way to recover a lost pass phrase. If
the pass phrase is lost or forgotten, a new key must be generated and copied
to the corresponding public key to other machines.
Exports the public key from the switch to a specified remote host to support
outgoing connections from the switch to a remote host. This option can only
be performed by a configured user. The successfully exported public key must
be appended to the authorized_keys file on the remote host. Use the cat
~/.ssh/outgoing.pub >> ~/.ssh/authorized_keys command to append the
file.
exportpubkey prompts for IP Address, remote directory, login name and
password. Refer to importpubkey for a description of these parameters.
Deletes the private key for outgoing connection from the switch. This option
can only be performed by a configured user. Deletion of a configured user's
private keys effectively blocks outgoing connections initiated by this user that
rely on public key authentication with a remote host.
