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 information about the command syntax for configuring the command
history buffer, see history size.
To display the history buffer, see show history.
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 guide describes the negation effect
for all applicable commands.
Command Completion
An appropriate error message displays if the entered command is incomplete or invalid; or has
missing or invalid parameters. This assists in entering the correct command.
