Issue Description

After the upgrade from V1 to V5, customer can’t login with SSH, how to solve it?

Solution

For the V5 version, the length of the SSH key pair must be greater than 2048. And this requirement does not apply to V1.
So customer can re-create the RSA key with follow commands:
[sysname] rsa local-key-pair destroy
[sysname] rsa local-key-pair create
