Enabling Debugging for a Feature
To enable debugging for a feature, type enter the debug command in EXEC or administration EXEC
mode and then enable the feature for debugging. For example:
RP/0/RSP0/CPU0:router# debug
RP/0/RSP0/CPU0:router(debug)# aaa all
RP/0/RSP0/CPU0:router(debug)# exit
You can also enter the complete command from EXEC mode, as shown in the following example:
RP/0/RSP0/CPU0:router# debug aaa all
Displaying Debugging Status
Enter the show debug command to display the debugging features enabled for your terminal session.
The terminal session is labeled tty and represents your connection to the router through a specific port,
which might be the console port, auxiliary port, or Management Ethernet interface. In the following
example, the command display indicates that debugging is enabled for two features (AAA and ipv4 io
icmp) from a terminal session on the console port of RSP1:
RP/0/RSP0/CPU0:router# show debug
#### debug flags set from tty 'con0_RSP1_CPU0' ####
aaa all flag is ON
ipv4 io icmp flag is ON
RP/0/RSP0/CPU0:router# no debug aaa all
RP/0/RSP0/CPU0:router# show debug
