Upgrading to a New Cisco IOS Release
Note You can press Ctrl-Z in any mode to immediately return to enable mode (Router#), instead of entering
exit, which returns you to the previous mode.
Note In the Cisco IAD2430 series IADs, the controller port syntax is x/y, where
slot can be 0 (where 0 is the T1/E1 controller on a VWIC) or 1 (the onboard T1/E1), and
port can be 0 (the first port) or 1 (the second port).
See the “Port Numbering Conventions” section on page 1-5.
Undoing a Command or Feature
If you want to undo a command you entered or disable a feature, enter the keyword no before most
commands; for example, no ip routing.
Saving Configuration Changes
You need to enter the copy running-config startup-config command to save your configuration
changes to NVRAM, so the changes are not lost if there is a system reload or power outage. For example:
Router# copy running-config startup-config
Building configuration...
It might take a minute or two to save the configuration to NVRAM. After the configuration has been
saved, the following appears:
[OK]
Router#
Upgrading to a New Cisco IOS Release
