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 debugging 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.
