The user EXEC commands are not saved when the switch reboots.

For example, you must enter the nameif command for an interface first because many subsequent commands use the name of the interface. Global Configuration mode : Global configuration commands apply to features that affect the device as a whole. The following is partial sample output from the more nvram:startup-config begin privileged EXEC mode command that begins unfiltered output with the first line that contains the regular expression ip.
