Disabling Debugging for All Services Started at All Terminal Sessions

Use the undebug all all-tty command to turn off debugging for all services that have been started from
all terminal sessions. For example if you enter this command while connected to the router through the
console port on the active RP, all debug sessions started from all ports are disabled. In the following
example, debugging for all services and ports is disabled and then verified:
RP/0/0/CPU0:router# undebug all all-tty
RP/0/0/CPU0:router# show debug
No matching debug flags set

Configuration Failures During a Commit Operation

A target configuration is added to the running configuration of a router when the commit command is
entered. During this operation, the changes are automatically verified by the other components in the
system. If successful, the configuration becomes part of the running configuration. If some configuration
items fail, an error message is returned.
To display the configuration items that failed and see the cause of each failure, type the show
configuration failed command.
The show configuration failed command can be entered in either the EXEC mode or any configuration
Note
mode. In any mode, the configuration failures from the most recent commit operation are displayed.
In the following example, a configuration error occurs when an invalid commit operation is attempted:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# taskgroup alr
RP/0/RP0/CPU0:router(config-tg)# description this is an example of an invalid task group
RP/0/RP0/CPU0:router(config-tg)# commit
% Failed to commit one or more configuration items. Please use 'show configuration failed'
to view the errors
!To display the configuration items that failed, including a description of the error, type the
show configuration failed command:
P/0/RSP0/CPU0:router(config-tg)# show configuration failed
