Description (partial)


When a 'speed 10' command is used for some fex ports and the user downgrades to a lower version, the software does not provide a warning message to the user to remove the command nor does it prevent the downgrade from happening.

The user configures 'speed 10' for some fex interfaces and tries to downgrade to a lower version of software than 7.0(1)N1(1).
