Enabling Debugging for a Feature

To enable debugging for a feature, enter the debug command in EXEC or administration EXEC mode 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

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 RP1:

RP/0/RP0/CPU0:router# show debug

#### debug flags set from tty 'con0_RP1_CPU0' ####

aaa all flag is ON

ipv4 io icmp flag is ON

RP/0/RP0/CPU0:router# no debug aaa all

RP/0/RP0/CPU0:router# show debug

#### debug flags set from tty 'con0_RP1_CPU0' ####

ipv4 io icmp flag is ON

The preceding example is for a Cisco CRS-1 router. On a Cisco XR 12000 Series Router, the slot number of the tty ID is 0 or 1 instead of RP0 or RP1.
