After this command is performed to end the public key edit procedure, the system
will check the validity of the key before saving the input public key. If the public
key string contains any illegal character, the system will prompt the failure of the
configuration and the configured key will be discarded; otherwise, the key is valid
and will be saved to the user public key list.

Syntax
rsa local-key-pair create

Parameter
None
Description
Use the
rsa local-key-pair create
command to generate the RSA key pair
(including the host key and server key) of the server.
When configuring by this command, if the RSA key pair already exists, you receive
get a warning asking if you want to replace the existing one. Note that the host
key and the server key must have a difference of 128 bits at least, and that the
minimum and maximum lengths for the host key and the server key are 512 bits
and 2048 bits respectively.

Generating the RSA key pair of the server is the first step to perform after SSH
login. You will not need to generate the RSA key pair after rebooting the Switch.
login. You will not need to generate the RSA key pair after rebooting the Switch.
Related command:
rsa local-key-pair destroy
.
Example
To generate the local RSA key pair, enter the following:
[SW4500]rsa local-key-pair create
[SW4500]rsa local-key-pair create
The key name will be: SW4500_Host
The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Input the bits in the modulus[default = 512]:1024
