3.2.6 Fuzzy Match Support
Switch shell supports 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.
