Cisco CRS-1 Series Carrier Routing System Getting Started Guide
Chapter 2 Cisco IOS XR Basic Configuration Management
Managing Configuration Sessions
In the following example, the configuration commit encounters an error:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# taskgroup bgp
RP/0/RP0/CPU0:router(config-tg)# description this is a test of an invalid taskgroup
RP/0/RP0/CPU0:router(config-tg)# commit
% Failed to commit one or more configuration items. Please use 'show configurati
on failed' to view the errors
To display the configuration items that failed, enter the show configuration failed command. The output
from this command includes a description of the error:
RP/0/RP0/CPU0:router(config-tg)# show configuration failed
!! CONFIGURATION FAILED DUE TO SEMANTIC ERRORS
taskgroup bgp
!!% Usergroup/Taskgroup names cannot be taskid names
!
To display the configuration items that failed without the errors, enter the show configuration failed
noerror command:
RP/0/RP0/CPU0:router(config-tg)# show configuration failed noerror
!! CONFIGURATION FAILED DUE TO SEMANTIC ERRORS
taskgroup bgp
!
Clearing All Changes to a Target Configuration
To clear changes made to the target configuration without terminating the configuration session, enter
the clear command in global configuration mode. This command deletes any configuration changes that
have not been committed.
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/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface POS 0/3/0/1
RP/0/RP0/CPU0:router(config-if)# description this is my interface
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0
RP/0/RP0/CPU0:router(config-if)# shutdown
RP/0/RP0/CPU0:router(config-if)# exit
RP/0/RP0/CPU0:router(config)# show configuration
Building configuration...
interface POS0/3/0/1
description this is my interface
ipv4 address 10.1.1.1 255.0.0.0
shutdown
end
RP/0/RP0/CPU0:router(config)# clear
RP/0/RP0/CPU0:router(config)# show configuration
Building configuration...
end
