CAUTION:
■
When SSH protocol is specified, to ensure a successful login, you must
configure the AAA authentication using the
authentication-mode scheme
command.
■
The
protocol inbound ssh
configuration fails if you configured
authentication-mode password
or
authentication-mode none
. When
you configure SSH protocol successfully for the user interface, then you cannot
configure
authentication-mode password
or
authentication-mode none
any more.
Generating or destroying RSA key pairs
This configuration task is used to generate or destroy the server RSA key pair,
including the host RSA key pair and the server RSA key pair.
■
The name of the host RSA key pair is in the format of switch name plus _Host,
for example, 3Com_Host.
■
The name of the server RSA key pair is in the format of switch name plus
_Server, for example, 3Com_Server.
n
Server RSA key pair (3Com_Server) is not used in SSH2.0; therefore, when the
rsa
local-key-pair create
command is executed, the system only prompts you the
host RSA key pair (3Com_Host) is generated, and does not inform you the
information about the server RSA key pair even if the server RSA key pair is
generated in the background for the purpose of SSH1.x compatibility. You can use
the
display rsa local-key-pair public
command to display the generated key
pairs.
After you configure the
rsa local-key-pair
command, the system prompts you to
define the key length.
■
In SSH1.x, the key length is in the range of 512 to 2,048 (bits).
■
In SSH2.0, the key length is in the range of 768 to 2,048 (bits).

CAUTION:
■
For a successful SSH login, you must generate a local RSA key pair first.
