General Troubleshooting Information
This section provides the following general information for troubleshooting ATM SPA cards and their SPA interface processor (SIP) carrier cards:
Interpreting Console Error and System Messages
Refer to Cisco IOS XE System Messages document.
System error messages are organized in the documentation according to the particular system facility that produces the messages. The SIP and SPA error messages use the following facility names:
Cisco ASR 1000 Series SIP:
Cisco WebEx Node SPA:
Cisco WebEx Node SPA Service Engine:
- SPA Online Insertion and Removal—SPA_OIR
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.
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 Cisco IOS Debug Command Reference for 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 errors, as well as any errors that might occur during configuration of the ATM interfaces.
- debug atm events—Displays information about events that occur on the ATM interfaces, such as changes to the ATM SPA and ATM interface configuration, card and interface resets, and PVC creation.
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 from the ATM network.
Use the no debug all command to turn off all debugging displays.
For more information about these commands, see the Cisco IOS Debug Command Reference for your specific software release.
Using show Commands
There are several show commands that you can use to monitor and troubleshoot the SIP and SPA cards on Cisco ASR 1000 Series Routers. For more information on these commands, see the Performing Basic Interface Troubleshooting section and Verifying the Interface Configuration section in Configuring the ATM SPAs chapter.
