Commit Options - Cisco CRS-1 - Carrier Routing System Router Getting Started Manual

Managing Configuration Sessions
In the following example, the user first displays the active configuration, then makes the necessary
configuration changes, and displays the "merged" configuration. The merged configuration provides a
preview of what the new active configuration will be after the commit command is executed.
The "merged" configuration shows what the new running configuration will look like after the changes
Note
from the target configuration are committed. It does not represent the actual running configuration.
Display the currently running configuration:
Step 1
RP/0/RP0/CPU0:router# show running-config
Building configuration...
!! Last configuration change at 16:52:49 UTC Sun March 10 2004 by lab
!
hostname router
shutdown
end
Open a target configuration session and enter configuration changes:
Step 2
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface POS 0/3/0/3
RP/0/RP0/CPU0:router(config-if)# description faq
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0
Display the "merged" configuration before committing the new settings:
Step 3
RP/0/RP0/CPU0:router(config-if)# show configuration merge
Building configuration...
hostname router
interface POS0/3/0/3
description faq
ipv4 address 10.1.1.1 255.0.0.0
shutdown
end

Commit Command Options
Description
(Default) Commits only valid changes (best effort). Some configuration
changes might fail due to semantic errors.
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.
(Optional) Assigns a comment to a commit. This text comment is
displayed in the commit entry displayed with the show rollback points
[detailed] command.
The line argument is the text for the optional comment or label.
