Configuring supported protocols
c
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 SSHv2.0; 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 SSHv1.x compatibility. You can
