The failed configuration is loaded into the target configuration, minus the errors that caused the startup
configuration to fail.
RP/0/RP0/CPU0:router(config-bgp)# commit
Use the show configuration failed command to display failed items in the last configuration commit,
including reasons for the error.
In any mode, the configuration failures from the most recent commit operation are displayed.
The show configuration failed command can be used in EXEC mode and configuration mode. The
command is used in EXEC mode when the configuration does not load during startup. The command is
used in configuration mode to display information when a commit fails.
The following example shows the show configuration failed command.
RP/0/RP0/CPU0:router(config)# interface pos 0/6/0/4
RP/0/RP0/CPU0:router(config-if)# no vrf
RP/0/RP0/CPU0:router(config-if)# commit
% Failed to commit one or more configuration items during an atomic operation, no changes
have been made. Please use 'show configuration failed' to view the errors
RP/0/RP0/CPU0:router(config-if)# exit
RP/0/RP0/CPU0:router(config)# show configuration failed
Wed May 2 13:14:08.426 EST EDT
!! CONFIGURATION FAILED DUE TO SEMANTIC ERRORS interface POS0/6/0/4 no vrf !!
% The interface's numbered and unnumbered IPv4/IPv6 addresses must be removed prior to
changing or deleting the VRF !
Note The show configuration failed command in configuration mode only exists as long as the configuration
session is active. Once you exit configuration mode, the command cannot be used to display the failed
configuration.
Commit Configuration Failed
The following example shows an invalid task ID configuration that fails to commit. The show
configuration failed command provides information on why the configuration failed.
RP/0/RP0/CPU0:router(config)# taskgroup isis
