user entered a correct command under corresponding modes and the execution is successful.

current mode

3.2.6 Fuzzy Match Support
Switch shell support fuzzy match in searching command and keyword. Shell will recognize commands or
keywords correctly if the entered string causes no conflict.
For example:
1) For command "show interfaces status ethernet1/1", typing "sh in status ethernet1/1" will work.
2) However, for command "show running-config", the system will report a "> Ambiguous command!"
error if only "show r" is entered, as Shell is unable to tell whether it is "show run" or "show
running-config". Therefore, Shell will only recognize the command if "sh ru" is entered.
Explanation

error in parameter scope, type or format.
At least two interpretations is possible basing on
the current input.
The command is recognized, but no valid
parameter record is found.
The command is recognized, but this command
can not be used under current mode.
The command is recognized, but the prerequisite
command has not been configured.
Quotation marks are not used in pairs.
