One day the engineer configures the terminal (SSH client) and the router building remote connection on NE5000E (Version NE5000E-VRP5.30-22002W08) and the terminal enables the client software supporting SSH1.5. Execute rsa local-key-pair create under system mode and the device prompts failure.
Change sysname name and change "××××NE5000E" as "××××NE5KE", and then the problem is solved.
rsa local-key-pair create is to create local RSA host key pairs and server key pairs. The naming of key pairs is router name _server and router name _host. The minimum length of server key pairs and host key pairs is 512-bit and the maximum length is 2048-bit. If sysname of the router is too long, the execution of the command will fail.
