3Com Switch 4500 Family - Ssh Authentication-Type Default

1-20
After execution of this command, the system automatically transforms the public key file into PKCS
format, and imports the peer public key. This requires that you get a copy of the public key file from the
peer through FTP/TFTP.
z Only public key files in the format of SSH1 or SSH2 are supported.
z Currently, only public keys with the modulues being in the range 512 to 2048 bits can be imported
to the switch.
z You may use this command to configure an SSH peer’s public key on the current switch. After you
issue this command, the system will automatically identify the format of the public key, transforms
the public key into the PKCS format, and saves the public key locally. This public key configuration
method requires that the public key file be uploaded to the current switch through FTP or TFTP.
Examples
# Transform the format of client public key file abc and configure a public key named 123.
