■
You just need to execute the command once, with no further action required
even after the system is rebooted.
■
If you use this command to generate an RSA key provided an old one exits, the
system will prompt you whether to replace the previous one or not.
Creating an SSH user
This configuration task is used to configure an SSH user.
Note that: an SSH user created in this way adopts the default authentication type
if you do not use the
ssh user authentication-type command to specify an
authentication type for this user.
Configuring authentication type
New users must specify authentication type. Otherwise, they cannot access the
switch.
Note that:
■
Use the ssh authentication-type default command to configure the default
authentication type for all users.
■
Use the ssh user username authentication-type command to specify the
authentication type for a user.
■
When the two commands are configured simultaneously, and the
authentication types configured for the user (specified by
username ) are
different with each other, comply with the configuration of the ssh user
username authentication-type command.
c
CAUTION:
■
If RSA authentication type is defined, then the RSA public key of the client user
must be configured on the switch.
