Guidelines for Using Debug Commands Read the following guidelines before using debug commands to ensure appropriate results. • All debug commands are entered in privileged EXEC mode. • To view debugging messages on a console, enter the logging console debug command. • Most debug commands take no arguments. • To disable debugging, enter the undebug all command. • To use debug commands during a Telnet session on your router, enter the terminal monitor command. Caution Debugging is assigned a high priority in your router CPU process, and it can render your router unusable. For this reason, use debug commands only to troubleshoot specific problems. The best time to use debug commands is during periods of low network traffic so that other activity on the network is not adversely affected. You can find additional information and documentation about the debug commands in the Cisco IOS Debug Command Reference. debug atm errors Command Use the debug atm errors command to display ATM errors.

ATM Troubleshooting Commands
Table 14-2
describes some of the fields shown in the command output.
debug atm Commands
Use the
debug
commands to troubleshoot configuration problems that you might be having on your
network. The
debug
commands provide extensive, informative displays to help you interpret any
possible problems.
Guidelines for Using Debug Commands
Read the following guidelines before using debug commands to ensure appropriate results.
•
All debug commands are entered in privileged EXEC mode.
•
To view debugging messages on a console, enter the
logging console debug
command.
•
Most
debug
commands take no arguments.
•
To disable debugging, enter the
undebug all
command.
•
To use
debug
commands during a Telnet session on your router, enter the
terminal monitor
command.
Caution
Debugging is assigned a high priority in your router CPU process, and it can render your router unusable.
For this reason, use
debug
commands only to troubleshoot specific problems. The best time to use debug
commands is during periods of low network traffic so that other activity on the network is not adversely
affected.
You can find additional information and documentation about the
debug
commands in the
Cisco IOS
Debug Command Reference
.
debug atm errors Command
Use the
debug atm
errors
command to display ATM errors. The
no
form of this command disables
debugging output.
Example 14-4
shows a sample output.
