General Troubleshooting Information
This section describes general information for troubleshooting SIPs and SPAs.
Interpreting Console Error Messages
System error messages are organized according to the particular system facility that produces the messages. The SIP error messages use the following facility names:
Using debug Commands
Along with the other debug commands supported on the Cisco Aggregation Services Router 1000 Series, you can obtain specific debug information for the SIP on the Cisco ASR 1000 Series Routers using the debug hw-module command in privileged EXEC mode.
The debug hw-module command is intended for use by Cisco technical support personnel.
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 will affect system use.
For information about other debug commands supported on the Cisco Aggregation Services Router 1000 Series, refer to the following:
Using show Commands
There are several show commands that you can use to monitor and troubleshoot the SIP and SPA on the Cisco ASR 1000 Series Routers. This chapter describes using the show hw-module subslot command to perform troubleshooting of your SPA.
