By default, the SSH2.0 server is compatible with the SSH1.X server. If the client of SSH1.3
to SSH 1.99 should not be allowed to log in, you must run the undo ssh server
compatible-ssh1x enable command to disable the earlier version-compatible function. After
that, the SSH client that has the version number greater than 1.3 and smaller than 1.99,
including 1.3 and 1.99 cannot log in to the router.
