Managing Configuration Sessions

F I N A L D R A F T — C i s c o C o n f i d e n t i a l

In the following example, the user configures an interface but does not commit it. After reviewing the changes to the target configuration with the show configuration command, the user decides to remove the changes and start over by entering the clear command:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# interface Gi 0/3/0/1

RP/0/RSP0/CPU0:router(config-if)# description this is my interface

RP/0/RSP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0

RP/0/RSP0/CPU0:router(config-if)# shutdown

RP/0/RSP0/CPU0:router(config-if)# exit

RP/0/RSP0/CPU0:router(config)# show configuration

Building configuration...

interface Gi0/3/0/1 description this is my interface ipv4 address 10.1.1.1 255.0.0.0 shutdown

end

RP/0/RSP0/CPU0:router(config)# clear RP/0/RSP0/CPU0:router(config)# show configuration Building configuration...

end

Committing Changes to the Running Configuration

The changes in the target configuration do not become part of the running configuration until you type the commit command. When you commit a target configuration, you can use the commit command to do either of the following:

•Merge the target configuration with the running configuration to create a new running configuration.

•Replace the running configuration with the target configuration.

Note If you try to end a configuration session without saving your changes to the running configuration with the commit command, you are prompted to save the changes. See the “Ending a Configuration Session” section on page 3-31for more information.

To commit target configuration changes to the running configuration, type the commit command by itself or with one or more of the options described in Table 3-5.

Table 3-5 Commit Command Options

Command	Description
commit	(Default) Merges the target configuration with the running configuration
	and commits changes only if all changes in the target configuration pass
	the semantic verification process. If any semantic errors are found, none
	of the configuration changes takes effect.
commit best-effort	Merges the target configuration with the running configuration and
	commits only valid changes (best effort). Some configuration changes
	might fail due to semantic errors.
