Enabling Debugging for a Feature

To enable debugging for a feature, enter the debug command and then enable the feature for debugging.
For example:
RP/0/RP0/CPU0:router# debug
RP/0/RP0/CPU0:router(debug)# aaa all
RP/0/RP0/CPU0:router(debug)# exit
You can also enter the complete command from EXEC mode, as shown in the following example:
RP/0/RP0/CPU0:router# debug aaa all
Disabling Debugging
Use the no form of the debug command to turn off debugging for the service or subsystem.
The undebug all or no debug all command is used to turn off all debugging on the system. For example:
RP/0/RP0/CPU0:router# undebug all
RP/0/RP0/CPU0:router# show debug
No matching debug flags set
In the following example, the no debug command is used to disable debugging for the AAA feature:
RP/0/RP0/CPU0:router# no debug aaa all
RP/0/RP0/CPU0:router# show debug
####
ipv4 io icmp flag is ON
You can also turn off debugging from the undebug mode, as shown in the following example:
RP/0/RP0/CPU0:router# undebug
RP/0/RP0/CPU0:router(undebug)# aaa all
RP/0/RP0/CPU0:router(undebug)# exit
