each command mode or a list of associated keywords and arguments for any command.
Table 5-4 Help commands
Reversing a command or disabling a function
When you want to reverse the action of a command that you previously issued or disable a
feature or a function, use the no form. For example, running no shutdown in interface
configuration mode as follows reverses the shutdown of an interface:
CIGESM1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
CIGESM1(config)#interface g0/17
CIGESM1(config-if)#no shutdown
Also, you can disable the command by recalling the command (use the up and down arrow
keys) and simply adding no at the beginning of the line.
Saving a configuration
To save the configuration or changes that you made, enter this privileged EXEC command:
Switch# copy running-config startup-config
This command copies the current configuration set in the flash memory to NVRAM as the
startup configuration set. If the command was not issued or if it failed, the changes you made
will be lost the next time the switch reloads.
