Using the CLI To Implement Configuration Changes
How To Cancel Changes You Have Made to the Running-Config File.
If you use the CLI to change parameter settings in the running-config file, and
then decide that you don’t want those changes to remain, you can use either
of the following methods to remove them:
■ Manually enter the earlier values you had for the changed settings. (This
is recommended if you want to restore a small number of parameter
settings to their previous boot-up values.)
■ Update the running-config file to match the startup-config file by reboot-
ing the switch. (This is recommended if you want to restore a larger
number of parameter settings to their previous boot-up values.)
If you use the CLI to change a parameter setting, and then execute the
boot
command without first executing the
write memory command to save the
change, the switch prompts you to specify whether to save the changes in the
current running-config file. For example:
ProCurve(config)# interface e 1 disable
Disables port 1 in the running configuration, which causes port 1 to block all traffic.
ProCurve(config)# boot
Device will be rebooted, do you want to continue [y/n]? y
Do you want to save current configuration [y/n]?
Press [Y] to continue the rebooting process.
You will then see this prompt.
Figure 6-2. Boot Prompt for an Unsaved Configuration
The above prompt means that one or more parameter settings in the running-
config file differ from their counterparts in the startup-config file and you need
to choose which config file to retain and which to discard.
■ If you want to update the startup-config file to match the running-config
file, press
[Y] for “yes”. (This means that the changes you entered in the
running-config file will be saved in the startup-config file.)
■ If you want to discard the changes you made to the running-config file so
that it will match the startup-config file, then press
[N] for “no”. (This
means that the switch will discard the changes you entered in the running-
config file and will update the running-config file to match the startup-
config file.)
