1.使用puttygen.exe计算RSA
2.保存公钥和私钥
公钥：pub.key 注意：公钥上传到交换机（FTP等方式）。
私钥:private.ppk
3.配置交换机
<Switch> system-view
[Switch] public-key local create rsa
The range of public key size is (512 ~ 2048).
If the key modulus is greater than 512, it will take a few minutes.
Press CTRL+C to abort.
Input the modulus length [default = 1024]:
