Using debug Commands
This section provides details regarding debug commands used for an ATM SPA.
General debug Commands
Along with the other debug commands supported on the Cisco ASR 1000 Series Routers, you can obtain
specific debug information for SPAs on the Cisco ASR 1000 Series Routers using the debug hw-module
subslot privileged exec command.
Caution Because debugging output is assigned high priority in the CPU process, it can render the system unusable.
For this reason, use debug commands only to troubleshoot specific problems or during troubleshooting
sessions with Cisco technical support staff. Moreover, it is best to use debug commands during periods
of lower network traffic and fewer users. Debugging during these periods decreases the likelihood that
increased debug command processing overhead can affect system use.
The debug hw-module subslot command is intended for use by Cisco Systems technical support personnel.
For more information about the debug hw-module subslot command and about other debug commands that
can be used on a Cisco ASR 1000 Series Routers, refer to the
your specific software.
ATM debug Commands
The following debug commands can be useful when troubleshooting specific ATM problems on an ATM
interface or subinterface:
• debug atm errors—Displays errors that occur on an ATM interface, such as encapsulation and framing
• debug atm events—Displays information about events that occur on the ATM interfaces, such as changes
Note The output of debug atm events can be extremely verbose and can cause problems if large numbers of
ATM VCs are configured. The command should only be used when a few VCs are configured.
• debug atm oam—Displays the contents of ATM operation and maintenance (OAM) cells as they arrive
