Setting Up the Switch to Run SSH

Follow these steps to set up your switch to run SSH:
1.
OL-23400-01
Local authentication and authorization (for more information, see the
Local Authentication and Authorization" section on page
The switch supports Rivest, Shamir, and Adelman (RSA) authentication.
SSH supports only the execution-shell application.
The SSH server and the SSH client are supported only on DES (56-bit) and 3DES (168-bit) data

An RSA key pair generated by a SSHv1 server can be used by an SSHv2 server, and the reverse.
If you get CLI error messages after entering the crypto key generate rsa global configuration
command, an RSA key pair has not been generated. Reconfigure the hostname and domain, and then
enter the crypto key generate rsa command. For more information, see the
to Run SSH" section on page
When generating the RSA key pair, the message
you must configure a hostname by using the hostname global configuration command.
When generating the RSA key pair, the message
must configure an IP domain name by using the ip domain-name global configuration command.
When configuring the local authentication and authorization authentication method, make sure that
AAA is disabled on the console.
