Chapter 4 Configuring General Router Features

Managing Configuration Sessions

Starting a Configuration Session

When you place the router in global configuration mode or administration configuration mode using the configure command, a new target configuration session is created. The target configuration allows you to enter, review, and verify configuration changes without impacting the running configuration.

Note The target configuration is not a copy of the running configuration; the target configuration contains only the configuration commands entered during the target configuration session.

While in configuration mode, you can enter all Cisco IOS XR software commands that are supported in that configuration mode. Each command is added to the target configuration. You can view the target configuration by entering the show configuration command in configuration mode. The target configuration is not applied until you enter the commit command, as described in the “Committing Changes to the Running Configuration” section on page 4-34.

Target configurations can be saved to disk as nonactive configuration files. These saved files can be loaded, further modified, and committed at a later time. For more information, see the “Saving the Target Configuration to a File” section on page 4-33.

Examples

This example shows a simple owner SDR configuration session in which the target configuration is created and previewed in global configuration mode:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# interface POS 0/2/0/1

RP/0/RP0/CPU0:router(config-if)# description faq

RP/0/RP0/CPU0:router(config-if)#ipv4 address 10.10.10.10 255.0.0.0

RP/0/RP0/CPU0:router(config-if)# show configuration

Building configuration...

interface POS0/0/0/1 description faq

ipv4 address 10.10.10.10 255.0.0.0 end

The following example shows a simple administration configuration session in which the target configuration is created and previewed in administration configuration mode:

RP/0/RP0/CPU0:router# admin

RP/0/RP0/CPU0:router(admin)# configure

RP/0/RP0/CPU0:router(admin-config)# sdr test

RP/0/RP0/CPU0:router(admin-config-sdr:test)# location 0/1/SP

RP/0/RP0/CPU0:router(admin-config-sdr:test)# show configuration

Building configuration...

sdr test location 0/1/SP

!
