By default, the history buffer system is enabled, but it can be disabled at any time.
For more information on enabling or disabling the history buffer, refer to the history
command.
There is a standard default number of commands that are stored in the buffer. The
standard number of 10 commands can be increased to 216. By configuring 0, the
effect is the same as disabling the history buffer system. For more information on
configuring the command history buffer, refer to the history size command.
To display the history buffer, refer to the show history command.
Negating the Effect of Commands
For many configuration commands, the prefix keyword no can be entered to
cancel the effect of a command or reset the configuration to the default value. This
Reference Guide provides a description of the negation effect for each CLI
command.
Command Completion
If the command entered is incomplete, invalid or has missing or invalid parameters,
then the appropriate error message is displayed. This assists in entering the
correct command. By pressing Tab after an incomplete command is entered, the
system will attempt to identify and complete the command. If the characters
already entered are not enough for the system to identify a single matching
command, press ? to display the available commands matching the characters
already entered.
